You are the man! Saved me from buying another setup. Ive watched a couple of your videos just now just to stay informed and prepared for the future. instead of going into panic mode i now feel confident in repairs and i am no longer ignorant on alot of the pump parts and how they work. I suggest anyone reading this watch his other videos to be prepared because all moving parts fail eventually

[@DAVIDCGRIMES]

By far this is one of the best how to repair video I have ever seen! (and I have seen hundreds). Very straightforward and logical. Great lighting and layout, etc. The host exudes experience! Great job!

[@verticle2612]

What a great instructional tutorial Mark! Walked outside this morning, my pool is gurgling, I flip on the lights, it’s drained to level with the strainer basket, I walk to the pump house and it’s draining from the backwash while in filter position. “Fkn pools broken again honey.” Instead of filling it in with concrete as I’ve threatened to do 18 times in the last 12 years I found you. I guess we’ll make it through season 13 now. Thanks Mark! CW4 Retired, 101st Airborne Division.

[@imaginitivity7853]

Man, that sounds familiar. We've been in this new house, with our first pool less than three months. I'm already approaching being a pool maintenance expert😂

Extremely helpful and detailed how-to-video. Called them to order the individual parts I needed and easily replaced them. The valve that was once so hard to turn is like new again. Thank you, Mark, for these amazing videos!

[@chrisb8288]

Thanks Mark, super helpful video. You have a great way of explaining everything so it’s easy to understand. I wish I had seen this before I replaced my key assembly because it would have been so much easier and less likely to make a mistake. I used a couple of C-clamps to compress the spring with the assembly on a bench to get the handle and pin back in and it worked well but your method looks easier. Great work and glad I found your videos!

[@DougEMac]

Thanks for this video! Saved myself headache and money in replacing just the key/seal assembly. Love learning how all this stuff works too!

[@illanaisme]

Thank you sir! I just did exactly what you said and got a few new o-rings, and the spacer, cleaned and re-lubed, now I can turn the knob to backwash so much easily.

[@MrYu2ube]

Excellent video - I had been told that parts weren't available for these units. Mine now runs like brand new after a clean-up.

[@jimw544]

Thank you Mark! Great info. Both of mine drag/chatter as you turn the handle. No leaks yes.

[@Chadsassou]

Thanks Mark for this detailed video. I replaced the diverter after it broke. But since there’s a slight leak from the backwash line and some sand goes into the pool after each backwash. I made sure to place the diverter in the right position. The window facing the pressure gage when in filter position. Thanks for your help

[@dorothychildrensballard7786]

Brought a new pool and back wash leaked slot spent money got another and it does the same thing . its the second year I've had this and the guy who told me each time that its a defect and I need a new one ,I wish I saw this ,and another one Las year ,we spent so much on this new pool. We had a pool 20 years with no problems ,this pool has been a huge headache ,definitely need a shut off value will be trying you before any other place. Thank you so much

[@brandonsifuentez3699]

This video is so clear and easy to understand I love it!

[@Johnny-cn6li]

Excellent video. I had a problem with turning the handle to the different positions and water leaking out the backwash port. Followed the instruction and everything is working again.

[@juicer52]

Thanks Mark for the tutorial. Side mount on Hayward sand 240 was "crunchy". Knocked out the handle while still mounted. Unlike the other videos that show reassembly with an elephant standing on the top of the key to be able to seat the spring, your technique was simple. Cleaned everything and lubed it all up and now smooth as silk. The spider gasket is showing wear so I have some spares that I will glue in when I get some Permatex 2 sealant. Seated the entire unit with little effort, placing 2 bolts/nuts alongside each other and then pressing down the opposite side to fasten and snug up the rest, and then attached handle afterwards as you show. I was overthinking it and thought if necessary, I could get two longer bolts for opposite sides to pull the unit together but that proved unnecessary. Thanks again for the clear tutorial with no music.

Update: just took my Hayward apart to inspect. Extremely dirty and without lube around the diverter shaft. No wonder it was hard to rotate. My local Pool Store has rebuild parts. Definitely need a new diverted with gasket. I’ll have it repaired and working again very soon. Couldn’t have done it without your videos. Thank you Mark.

[@church1060]

Very thorough.Excellent!!

[@gagirl0324]

I just noticed that all of a sudden ours is leaking pretty bad, so I think we need the o-ring that goes on the shaft/diverter. Can't really tell if it's leaking from the shaft/diverter area or from the area where the screws are installed, which would mean that we need the big O-ring. Thank you so much for this video! It is very easy to follow!

[@lapdawg60]

This was really thorough and to the point. Thank you! I have a sticky valve handle and it's getting worse. The sand filter unit is probably 17 or 18 years old, and I may just get a whole new multi-valve unit, as I'm suspecting I'd be pretty much replacing everything inside in any case. But that said, I haven't looked at cost difference yet. If it's a lot more, I may take it apart and look at it myself. Thank you for this great info and demo!

[@glennmisner8672]

Thanks for the video. Just one issue- on my 714 valve, I was able to relace the valve spider gasket. Mine was leaking to waste - truely wasting water! Was able to remove the old one easily as it wasn't glued in. Got the spider gasket and top o ring for about $11 on amazon.

[@cravenmorpus]

If your spider gasket is in the multiport body after you pull the key assembly off. Then you have the old style 710 valve. The 714 is the replacement. Notice how in the video the tip is perfectly round. After screws are screwed into sockets built into the multiport body, where the old style 710 was a sort of star shaped, with nuts on the bottom of the screws to seal the key assembly into place. You will also notice, on the 714 valve, there is a "bridge" in the spider gasket between two of the webbings, where as the old style valve is just a 5 spoke spider gasket (looks like a wheel with five openings connected to a tiny inner circle. No additional line running from one of the lines to the other. ) I googled the gasket on Amazon by rubron? Or something like that, if you look in the pictures carefully they are clearly deceiving people. They show you two different valves and gaskets, Even in the final photo it has a step 1-3 picture. First two steps are a close up of where the gasket goes, in the bottom of the body of a 710, the third picture shows a 714 valve(it's round around the screw inserts) The gasket that is built into the diverter is completely different from the other, yes people sell that gasket bc some valves have one that looks similar to the Hayward, but those go inside the multiport of different valves. Gasket built into a diverter are almost impossible to completely take out without damaging the diverter. The store on Amazon is a clear deception. Google "Hayward 710T key assembly" Then Google the same thing. Except 714T instead of 710 and look at the difference in the two.

[@BarryHarrellYouTube]

Great video. Mine has a rattle and I wonder if something is in the multiport and this video should help me to take it apart and see if I can find what's causing the issue. Thanks.

[@rosemariemontgomery353]

after working on my pool for two days and woke up to a pool with a low water level, when out of front door and water was draining into street, checked equipment and found no water leaking around equipment. I you tube" water leaking out while pump was in the filer mode: and thanks to Mark I found the problem my valve setting were very hard to move from position to another, I will be going to my pool supply company to purchase the complete assembly. I sure hope this will do the job.

I do carry the complete assembly as well as all the parts for your multiport. There are links in the video for these parts, if you need help feel free to contact me and l will be glad to help. Thanks for watching.

[@annakirschner6230]

You are my HERO. I’ve not seen such a detailed and well presented video on fixing a Hayward valve. Only question I have is; do you lube both sides of the spacer/bearing under the handle when you put it in?

[@HallmarkPoolSupplies]

You can lube both sides that will be fine.

[@mgamga9476]

Thankyou now my handle turns like new again. Amazing what some "O" RING lube will do. Now to figure out how to put sand in and start up for first time.

[@parkertara3483]

Love your videos, Mark! You do a fantastic job getting thru to guys like me. I bought a home with an inground pool with a vinyl liner. The pool has been winterized and covered but never in use for 4 +yrs. (and we had to waive all inspections!) It looked like a black swamp when we pulled the cover, complete with toads, polliwogs and an awful stench. We just got the water clear, and now I have the leak issue with the water coming from the waste line. I have ordered the key assembly, due in Wednesday. That gives me three days in high temps.. I have the pool turned off as it was losing LOTS of water fast. Is it possible to put the pool in recirc or something to keep pool circulating? Or will it always send water thru the leaky gasket? Anything that I should do in the mean time or ok to just wait for the part? Really don't want to lose the ground we have gained here. Thanks again for all the effort you put in to these. They are super helpful.

[@HallmarkPoolSupplies]

If you get a plug and plug the backwash line, then you can run the system in filter and you won’t lose any water. This will get you by until your parts come in.

[@RhettRobinson]

Just bought a house with a pool and found this channel. My handle barely turns so this looks like the right video for me! Other than turning the pump off, is there any other prep before disassembling the valve for repair?

[@HallmarkPoolSupplies]

As long as the filter system sits level or higher than the pool, no. If the filter system sits lower than the pool you may have to shut off the skimmer and drain line(s) as well as plug the return(s). Thanks for watching.

[@emh526]

Great video and everything was so clearly shown and described. One question, should lube be put on the gasket?

[@HallmarkPoolSupplies]

You can lube everything except the diverter gasket (spider gasket). Thanks for watching.

[@user-su2to9ky5f]

Thanks for the helpful videos! I have a brand new Hayward sand filter and am trying to use your videos to fix the leak in the backwash. I've disassembled the valve and have found that there is only one metal spacer and one plastic spacer on the spring of the handle. Should I replace the plastic one with a metal one? I should add that the plastic spacer doesn't seem to fit well at all. Thanks you for your help.

[@HallmarkPoolSupplies]

The non metallic bearing is plastic, this bearing is directly under the handle and allows the handle to turn easily and also helps with lift of the diverter. One of two metal washers/spacers go on top of the spring and the other goes under the spring These washers are a set and can be made in metal or plastic, it does not matter which one you have either will work.

[@akuamcclure4456]

Thank you for sharing this I was about to buy the whole multi port! I do have a question. We are slowly leaking water out of our backwash hose. I thought I heard you say the diverter would be the issue for that? Also, seem to have a leak around the sight glass, what do I do?

[@HallmarkPoolSupplies]

If you are leaking water out of the backwash while in the filter position it would be the gasket on the diverter. If the sight glass is leaking you need to replace the washer on the sight glass. If the sight glass washer is good you want to make sure the sight glass isn’t cracked. Thanks for watching.

[@elsavelaz]

❤ the video. Do you know how I know which part to buy for model Hawyward SP0715G50M ? Basically the sprint does not create compression and there is water leaking from around the valve. Thanks!

[@HallmarkPoolSupplies]

The valve you have is a 2'" valve, in the video I show a 1 1/2" valve. Some of the parts are the same and some parts are different, if you would like to contact me I will be glad to help you so that you can get the right parts.

[@NelsonEstradaSolorzano]

Excellent Tutorial. You get a 10 of 10. I need prices or small parts. The handle on my Vari-Flo Hayward filter (nearly identical to your video) is extremely hard to move. Also I need to know what is a good substitute to the Hayward Lube. I live in Central America and will order those parts and have them sent to my son's New York address but in the mean time, I want to lube the valve. Can I use the W-40?

[@HallmarkPoolSupplies]

All the parts to the Hayward valve in the video are linked in the description. If your valve is different then you can e mail me a picture of what you have and I will be glad to help. As a substitute you can use vaseline to lube, do not use WD-40.

[@doughale3024]

Great video. My problem is the sand filter like the one you're showing won't backwash. It did when i opened the pool a few days ago, but now there isn't any pressure. I clean out the basket strainers in pump & skimmer before backwashing anytime, & shut pump off before moving it from filter to backwash. Filter shows 5 psi (new gauge). Could it be pump instead of valve? Get lots of flow through outlet though. No leaks.

[@HallmarkPoolSupplies]

Put the valve on recirculate, if you have good flow in this position, you may need to backwash and rinse your filter thoroughly. If your flow is weak in the recirculate position then you may have a clogged pump. Here is a link on a video how to unclog your pump. If not, there could be a suction leak causing the pump to not hold full prime. Here is link to a video air bubbles in your pump, dealing with suction leaks. Hopefully this will help. kzbin.info/www/bejne/fXWViHeLlLt9pZI kzbin.info/www/bejne/iZqogHyujtV9a8k

Great information on how to repair and service the valve assembly. Should you put Jacks lube on the spider gasket or just install as is. I'm going to be replacing the diverter. Thanks.

[@HallmarkPoolSupplies]

The spider gasket needs to be glued down with 3M gasket adhesive.

Great video! When I took all screws off the top, it didn't pop up I had to take a flat head and tap end with a hammer to get it off. It doesn't separate. It looks like maybe the spring is rusted some. Could this be what's causing my pool to leak out of the backwash line when on filter?

[@HallmarkPoolSupplies]

Yes, you can replace the key assembly or repair. There are links for all of the parts for this valve in the description of this video. Feel free to contact me if you need help. Thanks for watching.

[@KC-dh3qo]

Excellent video! Question for you. We had our pool installed about a year ago. Basically the same filter. This season the filter isn't working correctly. Looks like it's not filtering the fine dirt. Pressure is fine and I've backwashed once a week. Any thoughts? The pool company came out and changed the sand but that didn't help.

[@HallmarkPoolSupplies]

You may have mustard algae it’s very fine and grows fast. When filtering or vacuuming the pool it can go through the filter back to the pool. Go to your local pool store and have your pool water tested, if you have mustard algae they can treat it. Once the algae is dead you need to vacuum to waste if not it will go back into the pool.

[@KC-dh3qo]

@@HallmarkPoolSupplies thanks for the info!

[@nicolemasterson6257]

May be silly question - but do we have to drain the water to do this? Our handle is stuck on the filter setting so we need to clean/fix it, but wasn’t sure what we needed to do about water levels when doing this! Thanks

[@HallmarkPoolSupplies]

In most cases no, it depends if you have an above ground pool or an in ground pool. If you have an above ground you can plug your skimmer and return. If you have an in ground pool you would not, unless the system is lower than the pool. If you have any questions feel free to contact me.

[@michaelhernandez3054]

Thank you so much for the video. I have a question. When I disassemble the valve, the coil was rusted and broken in half. This is on the valve that’s only one year old. What do you think could have caused this?

[@HallmarkPoolSupplies]

You need to have your water tested, if your balance is off this can be a problem. I do see a lot of damage on equipment due to cyanuric acid, low PH, salt and high chlorine. If you need any parts I will be glad to help. Thanks for watching.

[@jamiehatch3259]

I have a Hayward s310T. It’s at least 15 years old or more. I’ve never had to replace parts on it, but it definitely needs some parts replaced. I would like to replace the whole drop in top .

Do you have a 2" valve? If so you will use a different key assembly for that valve. Feel free to contact me I will be glad to help.

[@digitopdeals1398]

Thank you for the really detailed video. Is it normal to have some slow water flow through the waste line in recirculation mode? No leaks during filteration. But there is a slight air bubbling noise coming from the filter. Not perfect in filteration. Pool is hazy and hard to get total clarity.

[@HallmarkPoolSupplies]

You should not have any water flow out of the waste line while in the recirculate position. The clarity of the pool has nothing to do with the valve, but you may need to test your water or even use a clarifier. If you have done this you may need to change sand or backwash and rinse the filter thoroughly. Thanks for watching.

[@digitopdeals1398]

@@HallmarkPoolSupplies Thank you very much for the reply. I was assuming that a slight leak in the valve may be causing low suction and that could lead to poor filteration. Higest shown in gauge is 20psi.

Hi Mark I am in the process of finding a leak AND replacing the multi port valve as it’s stuck on backwash. Is there a way to force the diverted to the recycle position to get the water moving and slow the leak while I wait on the valve Replacement? Thanks for another outstanding and informative video. Much appreciated.

[@cherylmason8177]

Just a point of clarification, the pool is leaking from inside the pool and was before I uncapped the return jets. Although they could be leaking also. It appears that the concrete fix broke the seal around the steps at the very least. I’m just trying to get my Inground pool with Hayward S210T sand filter up and running for the year and hopefully continue to repair over next sever months. It has been quite a struggle.

[@HallmarkPoolSupplies]

You should be able take the valve apart, then you can clean and lube so you can reset the diverter in filter position. If you are still leaking out of the backwash then plug the backwash line temporarily, now you won’t lose water and you can run the pool until the repair is made.

[@MichaelJohnson-mz8bs]

Do you have a video replacing the whole value/housing ? I had a pressure gage just blowout. I wrapped it with Teflon tape and was able to screw back and it’s sticking. But now I am afraid so I just got a whole new unit but would like to see how it’s done. Not sure if it’s all unions or if I have some pipescemented.

[@Gazuni1]

Mark I have an above ground pool with water leaking from middle of multiport lever, going to rebuild the gaskets and o rings on multiport lever, but my question is I know I shut the power off to the pump and filter but do i move leave lever on filter or close before proceeding to next step? Also, do i bleed the sand filter tank before unscrewing all six screws or will water come gushing out from the top when i remove the muliport?

[@HallmarkPoolSupplies]

Leave the multiport in the filter position but plug the skimmer and return. Now you can remove the screws from the multiport to repair and you won’t get wet. You do not need to bleed the filter to make this repair. Thanks for watching.

[@wwjdcd]

Your videos have helped in many ways, now dealing with water leaking out when its in backwash position with the pump off looks like water is running straight out through the backwash without the pump being on. What could cause this issue?

[@HallmarkPoolSupplies]

Put the handle in the filter position when you are done backwashing. If you leave the handle in the backwash position then the water can continue run out even if the pump is off because the water can siphon out. Thanks for watching.

[@1Reganf]

Great video..... I made a little problem way worst... I stripped a screw and stripped the key insert placement for the screw. Is this fixable?

[@HallmarkPoolSupplies]

It sounds like you may have to replace the valve. I have all the parts to include the valve linked down below in the description of this video. Thanks for watching.

[@jconway-cy4ry]

Hi, Mark! My issue is that a small pinhole leak has appeared in the valve housing (i think you call it the hub.) Is there a way to just replace that outer piece? OR - is there a way for me to disassemble the valve and seal the hole/hairline crack? Any tips would be great! thanks for the super-helpful videos.

[@HallmarkPoolSupplies]

Because the valve is under pressure you can not seal it because it will eventually leak. If the valve has a pin hole or crack in it then you will need to replace the whole valve. Because the hub or body of the valve is damaged, replacing the valve will be cheaper than buying just the body. If you need a valve l do sell the valve as well as all the parts. If you email your contact info, l will be glad to help. My email is on my KZbin channel. Thanks for watching.

[@57FT]

Great video and very informative. I’m currently battling a over pressurization on the sand filter while on the filter position. I changed out the sand, checked the lateral, have great pressure and flow on the recirculating position but keep blowing the top off the sand filter when on filter position. I thought it may be the flow valve moving and causing a blockage but after watching this I don’t believe that’s it. Any pointers?

[@HallmarkPoolSupplies]

What filter brand and model do you have? I am not sure what type of filter you have, but if the top on your filter is threaded you may want to check the threads. If the threads are stripped this could be the problem.

[@57FT]

@@HallmarkPoolSupplies thank you for the reply. It’s a Hayward, so the top cap is a clamp style with a size valve mount.

[@HallmarkPoolSupplies]

A clamp style top is usually secure and does not come off, however you want to check the clamp itself along with the top cap (lid) and the rim on top of the filter to make sure that there is no damage. If there is no damage, re-install lid and see what happens. If you need further assistance feel free to contact me.

[@cravenmorpus]

Make sure you are backwashing for the appropriate amount of time, if your pool is dirty. That could mean multiple times a day, and make sure the sand you put in the tank is #20 silica sand.

You can rebuild, l have all the parts to include the valve itself linked down below in the description of this video. Thanks for watching.

Got all the way to the end and can't get the handle back on. The pin holes on the handle don't seem to line up well with the pin holes on the diverter because there's not enough clearance from the #5 top piece so its going in at an angle. Any suggestions? Also, do you lubricate the spider gasket?

[@HallmarkPoolSupplies]

Once the top is on you can move the handle up or down until the holes line up, sometimes it can be a little tricky but it will go on. As far as the spider gasket, you do not need to lubricate. Thanks for watching.

[@user-vw7ol1uc4q]

Thank you for your quick reply. Finally got the pin inserted after much difficulty. This video was extremely helpful with the rest of the operation. Clear and concise and with good work from your camera person. Saved me $75!

[@lindabradford9591]

The handle on mine doesn't seem like it is down into the say, filter slot. What does it need. Whole filter is only a few years old. Possibly a worn spring under the handle?

[@HallmarkPoolSupplies]

Possible worn spring and may need to lube. I would try lubing first, if it works you may be fine, if not then you may need to replace the spring and the non metallic bearing as well.

[@debbiekarst7710]

is the vari-flow valve supposed to connect to the white pipe of the laterals when reinserted? I still have sand spewing into the pool after replacing the laterals and parts in the valve.

[@HallmarkPoolSupplies]

Yes, if you have sand going back into the pool you may need to check your lateral assembly. In order to check this you will have to remove the sand from the tank. Thanks for watching.

I’m having trouble with that yellow spacer. For some reason I keep damaging them. My filter is 6 months old and I’ve already replaced two. Do you think I’m pressing the handle down to far when on rotating it? I don’t feel any restrictions when I’m rotating the handle

[@HallmarkPoolSupplies]

The handle should rotate smoothly, without having to press the handle all the way down. Lubing your valve will make for less wear and easier operation. Thanks for watching.

[@Derek.Naquin]

@@HallmarkPoolSupplies thanks for your reply. Should I lube the spider gasket also?

[@HallmarkPoolSupplies]

The spider gasket does not need to be lubed.

[@loosestringsholdyou]

If the leak is only at the handle, would an o ring replacement fix it and where do i get one?

[@HallmarkPoolSupplies]

Yes, I have all the parts on my website, the links for these parts are in the description of this video. Thanks for watching.

[@eklypised]

Ours was leaking from the backwash pipe. So we ordered a new vari-flo valve. Now the new ones leaking from the top and back wash. Could it be the gasket or oring?

[@HallmarkPoolSupplies]

Yes, if this is happening on a new valve, try turning off the pump and rotating the valve all the way around and let the valve pop back into position. This should reseat the valve back in position, if not then l would replace the valve especially if it is new. Thanks for watching.

[@tommybouatic6044]

Hey Mark, I’m losing water level pass skimmer and there’s water coming out backwash discharge hose while in filter position

[@HallmarkPoolSupplies]

You need to replace the diverter gasket (spider gasket) if water is leaking out of the backwash while in filter. Thanks for watching.

[@stehimf1919]

I have a question. I replaced the whole top and went to install it and during the install the handle stayed good with compression but as I tightened the screws the handle now has a lot of play.

[@HallmarkPoolSupplies]

@@stehimf1919 Once the key assembly is tightened and installed the handle will have play, this is normal. Thanks for watching.

[@courthawk214]

Is it necessary to release any pressure? My pump is off, but pressure valve is reading max. I don’t know how to receive the pressure though.

[@HallmarkPoolSupplies]

It is not necessary to release any pressure when working on the multiport valve. When the system is off the pressure will drop, if not your pressure gauge may be stuck and you may need to replace the gauge. Thanks for watching.

[@beckistube]

We just received the key/seal assembly and didn’t realize we needed the spacers and the rubber gaskets for it. What all do we need? When we click on the link that says “shaft spacer/o-ring”..it pulls up a picture of an o-ring. My husband says it looks like we need a spacer and 2 o-rings for a 714 Hayward pump. Please help.

[@HallmarkPoolSupplies]

The part you are referring to is SPX0735GA, this is the o-ring / teflon shaft seal set.

[@oofgeg]

I replaced the handle and diverter because my handle had broken. It went smoothly in place but now water slowly leaks up around the handle. Any thoughts?

[@HallmarkPoolSupplies]

You need to check the o-rings on the shaft of the diverter. Thanks for watching.

[@johnmonkey1874]

I have a Vari-Flo Xl. I think it's around 9 or 10 years old. Is there no way to just replace the spider gasket instead of buying a whole new diverter? I have a new gasket, so why can't I just take the old one off and replace, gluing if necessary?

[@HallmarkPoolSupplies]

On the 714 valve the gasket is factory glued to the diverter and you have to replace the diverter if the gasket goes bad. On the 710 valve the gasket is glued down on the bottom of the multiport (not on the diverter), so you can replace just the gasket. It depends on which valve you have, if you have any questions feel free to contact me and I will be glad to help.

[@22mrwillie]

Do you need to drain the filter to take the assembly off?

[@HallmarkPoolSupplies]

No, thanks for watching.

[@leannewilliams6218]

Ime trying to find my o ring for multiport valve for hayward ver flo xl carnt find what size it ie same as the one you are useing in this video can you tell me what size i need please

[@HallmarkPoolSupplies]

If it’s the same one in the video, l have all the parts for this valve linked down below in the description of the video. Thanks for watching.

[@user-ws9pk9tq3p]

Would a bad seal cause poor suction at the skimmer after 10-15 mins of being on? Good suction when it first starts up, then poor suction.

[@HallmarkPoolSupplies]

Your multiport is under pressure, and has nothing to do with suction at the skimmer. It sounds like you need to backwash or you have a suction leak. There are several different things that could cause this, you could have a cracked pump lid, a bad gasket or o-ring on the lid, loose or cracked plumbing fittings or a cracked housing on the pump to name a few, I need more information in order to help. If you would like to check out my patreon page I will be glad to go into more detail on this situation.

[@ray.a7343]

I see now it's the rubber oring on the shaft .do u use a flat head ir just roll it down the shadmft thanks wish there was a video showing you in detail how to replace .I've seen 50 videos no one shows exactly how to replace thanks

[@HallmarkPoolSupplies]

In this video l show how to take the valve apart, how to repair the valve and how to put the valve back together. If you need parts email your contact info and l will be glad to help. My email is on my KZbin channel.

[@hanzberger8751]

Is there a way to add a bleeder valve for air to this filter? Where the guage is?

[@HallmarkPoolSupplies]

Yes, thanks for watching.

[@mikew4837]

Is there any other reason besides broken standpipe or laterals that sand gets into the pool? Replaced sandpiper and laterals and still get sand in the pool. It is correct size sand

[@HallmarkPoolSupplies]

If the stand pipe and laterals are good and you are using silica 20 filter sand then make sure you put the right amount of sand in your tank. To much sand can cause this.

[@mikew4837]

@@HallmarkPoolSupplies ok thanks. I have a hayward s180t and I put in 150 lbs with a size of .45 to .55mm. Very annoying problem 🙄

[@HallmarkPoolSupplies]

@@mikew4837 The amount of sand and size would be correct, however you may need to reinspect your lateral assembly if this continues. Contact me if you have any questions I will be glad to help.

[@ricardoherrera8662]

My filter/valve are around 3 months old. The valve will not budge. I loosened all the perimeter valve screws. The handle is pointing 180 degrees away from where yours is as you are taking it apart. Any suggestions?

[@HallmarkPoolSupplies]

The valve l was working on was for a sand filter, valves for DE filters work the same but the handles are usually 180 degrees opposite. If you have a sand filter, make sure your handle or diverter is set correctly. Thanks for watching.

[@ricardoherrera8662]

My filter is DE. I'll keep checking if any other videos on YT give me some info. When I first contacted Hayward they sent me a link for their services. It was in Canada, and I am in Puerto Rico. No use. I'll try as well at stores where I buy pool supplies. Thanks for taking the time to prepare videos to help us out.

[@ridebmx82]

I am having an issue. I started up my pool and my filter is leaking water where the pressure gauge is. What would cause this to happen.

[@HallmarkPoolSupplies]

Make sure that the pressure gauge is Teflon taped and hand tightened, also make sure that the gauge is not cross threaded. If everything is good you may have to replace the gauge.

[@steveadams8487]

Amazon says they have rebuild kits including the spider gasket. What is the part called that you can’t get the gasket for so I can order it???

[@steveadams8487]

When I search for Cari-flow valve, it always leads me to the whole assembly. All I need is the metal shaft part that has the spider gasket. Why does Amazon say they have just the gasket?

[@steveadams8487]

Vari-flow

[@HallmarkPoolSupplies]

At one time you could order just the gasket for the diverter on a 714 T top mount multiport ,Hayward no longer offers the gasket separate. Today the gasket is molded on to the diverter. If you have a 710 series side mount multiport then you can order the spider gasket by itself. You have to make sure that you are getting the right part or gasket that you need, because there is a difference. If you need help, email your contact info and l will be glad to help. My email is on my KZbin channel. Thanks for watching.

[@steveadams8487]

I just sent you an email, inquiring about the key assembly, how much it costs, and does it have the O rings installed on the shaft, as well as the spider gasket? I live in S Florida, and I need it soon, so I won’t have to fight an algae war after repairing the valve, lol!

[@richardgagalac2601]

Hi Mark how much is the diverter for hayward st220T? And how can i order?

[@HallmarkPoolSupplies]

Here is the link for the diverter. hallmarkpoolsupplies.com/p-1864-spx0714ca-sp0714t-mpv.aspx I also included the link for the key assembly. hallmarkpoolsupplies.com/p-1861-spx0714ba-sp0714t-mpv.aspx

[@rauelb09]

How do you get the glued in gasket out??

[@HallmarkPoolSupplies]

If you have the same valve in the video, that valve is the SP714T. You have to replace the diverter, because the gasket is not sold separately, it is factory glued on the diverter. Most people will replace the key assembly. All the parts for this valve are linked in the description of this video. If you have a different valve, then service and parts will be different. Thanks for watching.
