It's allow to connect the water supply into return pipe with ball valve?,when you use back wash the water in pool is rinsed and need to supply water again.

[@HallmarkPoolSupplies]

The water supply line for filling a pool is usually run separate.

[@fajava83]

Hi Mark, I have a Sta Rite BHR200 Sand filter with this problem. However, I don't seem to find the multi-port valve from this brand anywhere to replace it. What replacement part would you suggest to me to replace the multi-port valve with ? Is there any other compatible brand?

[@HallmarkPoolSupplies]

If you would like to email me some pictures of your system, I will be glad to help.

[@heatheresteubing-fisher9729]

I just experienced this and it is because I didn’t turn my knob off of backwash after turning pump off - there was already a siphon created by the outlets, so the water kept flowing.

[@TeenaSpivey]

Mark, I dropped in a new Key Assembly 714 on my Hayward Sand Filter, put the o-ring on it lubed it before dropping it back in and it seemed to be working fine, however the site glass is full of water, is it suppose to be? I also added a Ball Valve to open during the back wash cycle and I close it afterwards. I went out today and noticed there is water sitting on top of the Key Assembly. What am I missing? and again, is water suppose to be sitting in the site glass?

[@HallmarkPoolSupplies]

If this is a new key assembly it should not be leaking. You will probably have to replace. I would contact Hayward at customer support and they should be able to help. Thanks for watching.

[@jfriedman9613]

Our Heyward is dripping at the bottom of the sand filter where the plastic screw on the bottom is located. Any suggestions?

[@HallmarkPoolSupplies]

Check the drain cap for cracks, and the washer for damage.

[@Relle_Banks]

If you go the wrong way when turning your port you can also cause your gasket to not seat properly simply repeat process the correct way might fix your issue

[@jasmynegreenlee123]

I was losing water in my pool but get this, my DE filter grids were full of DE on the inside and not coating the outside as they normally should despite me recharging them on Filter mode. Is it possible that my multiport valve caused this?

[@HallmarkPoolSupplies]

If you are leaking out of the backwash while running in filter, then you need to check your multiport valve.

[@fawaid1a]

Hello and good day I have a question for you as a professional. I have a Hayward pump with an output of 1.5 HP. Now I wanted to know how many gallon in a minute or hour this filters. I have a pool volume of 22m3. Would look forward to an answer from you and remain with the greetings to you.

[@HallmarkPoolSupplies]

What model pump do you have? Hayward makes several 1.5 HP pumps, (In ground, above ground, variable speed) all of these pumps have different specs.

[@TeenaSpivey]

Mark I just sent a comment but wasnt sure if it went through. I dropped in a 714 Key Assembly, made sure the 0-ring was good, lubed it, and screwed it back in. I added a ball valve to open/close during back wash cycle. I went out today and there is water sitting around the knob of the key assembly, what am I doing wrong? Also, the site glass is full of water, is it suppose to be?

[@HallmarkPoolSupplies]

If this is a new valve it should not be leaking. I would contact Hayward at customer support and they should be able to help. You will probably have to replace the key assembly. Thanks for watching.

[@zamszamundas]

If I forget to close that ball valve and start filtering is there gone be water loss? I forget to close mine and the pool was running on automatic filtering, the next day the water in the pool had decreased quite a bit

[@HallmarkPoolSupplies]

You will only lose water out of the backwash or waste line if your spider gasket is bad or your diverter is not set down properly. If you are leaking out of the backwash when in filter, you need to repair. The valve is just added insurance. Thanks for watching.

[@user-fw2zz1eo3z]

Mark I have a push pull backwash valve. How can I replace it with a multi valve type. I have a DE filter JANDY MODEL DEV48

[@HallmarkPoolSupplies]

According to the manufacturer the multiport valve for this filter has been discontinued. Thanks for watching.

[@Er-ym3ur]

I’m trying to setup an 18ft above the ground pool and I am using the aqua strong sand filter. I have put everything together and when I connect the hoses the hose with the top on it that you can turn on and off is shooting out water. Why is this happening?

[@HallmarkPoolSupplies]

Make sure that the o-ring is in place and not missing. If you have tighten the union on the hose you should be fine, if still leaking then you may need to check for any cracks on the housing or the hose. Thanks for watching.

[@bobgalvan]

SP071620tfv valve and I am looking for the gasket repair kit but have not found one. do you know where I might find one.

[@HallmarkPoolSupplies]

It sounds like you have an older 2” top mount multiport valve. If this valve is no longer made l might still be able to get parts. Email your contact info and some pictures of the valve and l will be glad to help. My email is on my KZbin channel. Thanks for watching.

[@markwashel8500]

I just recently replaced my multi port and when I turn pump on to backwash the water comes out weak instead of shooting out like it used to. Also my psi is only reading 6psi, any suggestions?

[@HallmarkPoolSupplies]

You want to make sure that you have your valve installed correctly. Your valve will have a pump inlet, a return outlet and a waste outlet. If lines are switched this could be the problem. As a test you can run your pump in the recirculate position to see how the flow is. If everything is hooked up properly you may want to check your pump's impeller and make sure it is not clogged. Thanks for watching.

[@Bigwingrider1800]

I have 3 multi valves 1 is 15 ys old, 2nd is 10 but an extra, the 3rd is new today. its still leaking a couple of drops here and there. none out of the sight glass. I replaced the sand last week end back flushed and rinsed twice and still had sand in the pool. flush and rinsed again can to low of sand make this happen? It's a 150 lbs system. tried 2 different laterals and i was feeling sand on the return to pool. Confused PS: this filter has been running on an intex 1800 gal pools for over a decade. sand has been changed 3 times and never had this problem. sand .49/.20 is the sand Thanks in advance

[@HallmarkPoolSupplies]

Low sand will not cause this issue, you may need to check the laterals. The filter sand that you should be using is # 20 silica. Thanks for watching.

[@robinseute-morse7032]

Approximately how much should I be charged if I need a company to add a ball valve

[@HallmarkPoolSupplies]

The ball valve costs about 15 dollars, there is a link down below in the description if you need one. Most homeowners can install themselves, it is pretty easy to do. As for a labor charge you can contact your local pool company or service technician.

[@vicentee2687]

if the gasket is bad in the valve will it cause filtering problems like de blowing back into the pool

[@HallmarkPoolSupplies]

No, it can definitely cause a leak in the backwash/waste line, however if your gasket is bad then you need to replace. You need to backwash and rinse the filter if this problem persists, then you may need to check your filter grids/elements for damage.

[@vicentee2687]

@Hallmark Pool Supplies I just replace all of them today I ensured the manifold was seated properly and I'm still seeing blow back I even replaced the breather tube I'm not sure what the deal is. also I didn't recharge the filter with de I figured I'll just vacuum it up that leaked back into the pool

[@tommys5749]

@@vicentee2687 I'm having this exact issue. What was your issue?

[@vicentee2687]

@tommys5749 I didn't tighten the manifold all the way snug and the pressure was lifting it slightly letting de pass by

[@tommys5749]

@@vicentee2687 Just took mine apart and the manifold was cracked. I put heavy duty epoxy. Hopefully it holds. Thanks

[@fatsilentbob]

never would have though about a valve

[@michellelee5706]

I just bought a brand new filter and if filter is on water pours out backwash. Returned it got another new one and same exact thing

[@HallmarkPoolSupplies]

If this happens, turn off the system and rotate the handle and reset back in filter position. Sometimes the diverter does not set down properly. This should fix it, if you have any questions feel free to contact me I will be glad to help.

[@gregjones1589]

Where is the link in how to fix leak coming out my backwash when filter is on?

@@HallmarkPoolSupplies thank you but I have an older Pentair. I can’t find the model. It has the pvc pipes running into it so you can’t replace the entire unit. Got a gasket and going to try snd replace it. I can’t find anything online on how to replace it. Any help would be appreciated.

Do not do this, bad idea, if you forget to open the valve it will blow you tank apart. I know I did it😩
