Great, clear, instructive video. The presenter doesn't pretend to be a "TV host" with useless time wasting blather. The tutorial was perfectly suited for this repair job. I followed the steps and procedures exactly as the video demonstrates. The repairs worked perfectly. Thank you.

[@todd8155]

Agreed, the precise info needed to carry out the repair presented in a professional manner without wasting my time. Also, this is a Pentair official video so one can trust the information.

[@tedgage8180]

Best, precise instruction guide that I have ever seen on KZbin. Great job.

[@texasrickg]

Not sure how many folks are looking at this video in mid 2021, but I wanted to share my experience. 1. GREAT instructional video for the inner workings and parts of this pump (good job Pentair!) 2. NOTE: this is being demonstrated on a NEW unit, so no calcium build-up, stuck bolts, degraded seals, etc. 3. NOTE: The work is being done on a bench...... much easier access. My experience.. I not only have the main variable speed main pump, but also another pump for the in-floor cleaning system (Wonderful, by the way) However, this put the main pump between the 'in-floor' pump and the main filter tank. 6 inch or less clearance all the way around. Extremely tight, cramped quarters.. much bending, crouching, etc. Also the main 'housing' (with the basket) is glued in place to both the feeds from the skimmer/bottom drain as well as the line to the filter tank.. no moving this.. Where this was an 11 minute video, it took me 5+ hours.. I had ALL tools and part needed 'on-hand'. This is not for the faint of heart... with that being said, without this video, I would not have done the work myself, saving multiple hundreds of $$ I'm sure. If I ever need to do this again, I will definitely just disconnect the wiring, and take as much as I can to my workbench...

[@chuckallen9906]

I just did mine and I agree about the stuck bolts and missing seals but the video is on point about the process except for the backend of that new motor. I have an older pump which I have rehabed with new seals several times over 12 years and it has a fan on the back which makes using a wrench impossible. There is a screwdriver slot in the end of the shaft to hold it, but it is not friendly, and invariably the impeller is hardest part to remove (without breaking it... be prepared). Beyond that this job is a piece of cake and anyone who can follow these instructions (with the proper tools) can do it. Your pump is the tight space is a whold different deal... mine is pool use and sitting on a slab behind my garage...

[@texasrickg]

@@chuckallen9906 Thanks for the words of advice/encouragement. My first attempt didn't work.. 2nd try, disconnected electrical and move the whole thing to the workbench.. same deal with the slot for taking off the impeller, but on the bench I at least could get some leverage! And.. so far, so good!!!

[@texasrickg]

UPDATE: 1st attempt was not successful. Confirmed leak the day after posting this. Just repeated the process, except... I disconnected power and took the whole unit (flange/seal plate) and put it on the workbench. Able to spend the time with all the 'fussy bits' and make sure they were done correctly. So far so good. So if you are needing to fix a leaking pump, it definitely can be done.. just follow the sage advice of working smarter, not harder...

[@MarkNOTW]

One other tip is to break loose the 4 bolts holding the motor to the seal plate BEFORE removing the entire assembly from the main pump. Those are the bolts that get stuck most often.

[@Shadypoolguy]

Why do you think pool guys charge so much now? We can have this done in about 5/10 minutes sometimes more. We work in cramped none desirable conditions, sweating our asses off to get the job done. Having done about 250/300 of these it’s never fun, and usually only Pentair pumps…

[@NicholasLongo]

Just used this video tutorial. Cost me $30 total and it worked like a charm.

[@markherring3404]

Thanks for this amazing video, made the job way easier. I didn’t remove the pump and put it on the workbench but rather did it in the pool house. Other than my bolts being much harder to remove, and some corrosion on one area, it was very easy. It took me just over 2 hours. Could not have done this without this video.

[@WaltGambirazio]

How much??

[@markherring3404]

@@WaltGambirazio in US on Amazon about $30 (Pentair 356198)

[@4Liebmans]

This is by far the best instructional video I’ve ever watched!

[@PlayMoxie]

I live in Florida fort myers and many of these pumps were completely submerged. I put new motors on them and the drives still worked. Amazing

[@gman4dx266]

I'm in Cape Coral and just bought a used IntelliFlo off Facebook marketplace for 300$. The bearings were shot in it. I opened up the drive unit just to check it out - there's never been a spec of dust or drop of water in it! They do an amazing job of sealing these puppies up! I tossed new bearings and a seal set into it and it's running perfect

[@fabp4289]

Thanks for the video very informative 😊helped me very much I am in Houston Texas Heat 112 degrees and this video helped me finish the job pretty quick

[@danielduran3265]

The shaft seal needs silicone? If so which silicone can we use? I did everything as shown but still have a leak around the shaft seal.

[@lannysalisbury6645]

I use GE100% waterproof silicone 2.8 Oz tube. Use the silicone and wait 24 hours before starting the pump.

[@jrviade85]

😂 silly boy lol 😂

[@EduardoEliasCanela]

Use the one that comes with the package directly from pentair

[@todd8155]

The supplied silicone lubricant is not the same as a silicone sealant.

[@Stenn333]

You'll hear different direction from different sources ...the directions that came with my Leslie's/Pentair seal kit say DO NOT USE any lube of any sort on "the mechanical seals" around the shaft...the white ceramic face seal and the black carbon seal, because getting even a trace of lube on these mating surfaces could reduce sealing and degrade the material, even though the back sides of these 2 seals would benefit from the lube (better it was PTFE than Silicone) as they have to be pressed in to their seats. But since you did NOT use lube, your leak could not be from not having it, unless they were damaged during insertion. Are you the only one that's ever serviced this pump ? Remember we have to pry the 2 "mechanical" seals, the white ceramic and it's mating carbon half....if we're too rough in prying, or pried too much all at once at one point, instead of going around prying a little at a time, you could gouge the verticle wall or the bottom mating surface of the housing when prying the old one out....then those marks or gouges, scratches, etc ..could allow a leak and that pump plate might have to be junked.

[@daultonruff2281]

Thanks for the video. It was helpful. Now to stick it on and see if it runs...after it stops raining.

[@haunthunterify]

Great step by step instructions. I was able to did the seal plate rebuild with no issues. Thank You!

EXCELLENT instructions!!!! Thank you!!

The kit comes with a packet of silicone to use on the rebuild. I also have a video on my channel on replacing the motor on a whisperflo, & I rebuild the pump as well as replacing the shaft seal. Here's the link, Thanks 👍 kzbin.info/www/bejne/r4DOqqOXbJmknNk

[@frankriano8309]

You mentioned adding silicone adhesive when placing the new seal in the seal plate. Is it adhesive or lubricant? If adhesive what kind do you use? Thanks

[@albertobu]

Any kind of silicone.. I recomend GE silicone II or Permatex RTV clear

[@TC-bj8pu]

Do you have a part number for the quick kit?

[@markleach2177]

Still have a leak from the pump body to the pump seal plate. I installed a new seal. I used the silicone lubricant.

[@rickbuckskin9385]

In the wiring it say L1 an L2 L2 has a post fir a wire but L1 doesn't , but it has a screw. On the old one both had a post to hook up Will this work if I put the wire on the screw

[@paualv468]

So you put silicone adhesive on the seal before you installed it? I’ve seen so many conflicting things about using anything on the seal! We’re trying to replace ours, and really need to do it right! Can you offer some advice please? Thanks!

[@JustinAlexanderBell]

He puts silicone ADHESIVE only onto the shaft seal lip that is pressed into the seal plate.

[@TooMuch637]

@@JustinAlexanderBell Is there a particular type of silicone adhesive that should be used? Or your basic Loctite brand marine grade good?

[@JustinAlexanderBell]

@@TooMuch637 I used an aquarium grade silicone adhesive as it's in direct contact with the plastic housing. Loctite might be fine but I'm not sure.

[@thormx47]

It comes with lube for the o-rings, not the silicone for the seal

[@jamiewhite1515]

excellent instructions....

[@jyoho55]

What do you do if you follow all the steps and the pump still has a little leak? I've installed 2 seals and there is still a little leak.

[@jadengilliam1494]

Make sure they’re seated properly and make use a little gasket glue (silicone) to hold them in place.

[@motocrosscrack]

has anyone ever had an issue with the rotating shaft assembly being stiff after installing new seals and impeller? I have done this exact replacement on my Whisperflo and once together, before even installing the defuser, the shaft doesn't spin freely. Its like the new seals are so tight that it doesn't rotate as freely.

[@SANDHAPPS]

I am having the same issue and trying to find the solution, have you? Thanks.

[@dwest8245]

Yes! This was perfect! Fantastic step by step

[@arat3807]

very easy to do all he is doing on a new pump and sitting on a Bench.

[@JP-ku3he]

I replaced all these seals seamed perfect but I put it back together and leaking even worse I did notice the propeller seal didn't seat flushed but no room to push it further

[@GunnerAl9]

This is the only video that shows adding silicone to the flange of the seal prior to installation and waiting 24 hours for it to dry. Most other videos just use seal lube. Not saying you're wrong, but I'm not sure who is right?

[@texasrickg]

My 2-cents worth.. I used the seal lube, no wait.. reassembled. All good.

[@totallyfrozen]

Just my opinion, but I think that if the silicon glue is absolutely necessary, it would have been included in the kit. After all, the o-ring lube is included in the kit. So why not the silicon too? I’m guessing it’s optional, but “best practice”.

[@albertobu]

@@totallyfrozen thats because this is expected to be installed by a professional, and they only add the lubricant as courtesy. Yes silicone is a must, its what is used from factory.

[@officerkrupke4966]

If you have a salt water pool, you need a seal that is specifically built for it.

[@lvsfineartssurvey]

need link to order kit, need a link to script. I typed on for myself to keep for future reference. But a good rule of thumb for any tutorial is to provide the script.

[@dharmon531]

Is it possible that this repair could eliminate the air in the basket and coming out of my return jets? Also, can this repair be done without removing the pump from it's location? The pump was installed without the ability to remove it from the system.

[@officerkrupke4966]

The o ring for the removeable suction strainer lid could be the problem. Replace this with a new one that you have applied silicone LUBE on, do not use silicone adhesive. They are two different silicone types. If after doing this you still have air leak, try replacing the o ring on the strainer basket drain plug if equpped, if it still has air bubbles, it probably is a poorly glued suction line fitting. Try pressing your finger around the joints, you may hear a difference in the air leak if you seal it with your finger. This can be fixed easily, just do a youtube search. Repairing pump would have no effect on air in basket. Air in basket is coming from cracked basket housing, or o ring for lid, or any suction line back to pool skimmer and main drains.

[@u2ooberboober]

Might want to get someone to install unions on the supply and return pipes, when the time comes..

[@totallyfrozen]

It could help. I also noticed my suction-side pool vacuum was sucking air through the hoses. So check your pool vacuum hoses and replace as necessary.

[@jeffryobrien3173]

What do I do if I accidentally touch the seal with my finger... or it gets dirty? What can I clean it with?

[@mguerramd]

After you take a few old ones apart, you realize you need to PUT ANTI-SEIZE on every fastener! Especially including the long through bolts that hold the end caps on the motor. When I install a new motor/pump assembly, I take it apart and put anti-seize on all the fasteners before placing it in service. If you have ever had to drill out or hacksaw off stuck fasteners, you know what I mean. Even the little screws that hold on the capacitor cover, ALL of them. One stuck fastener can ruin your whole day...

[@wwcranker]

That's not a 1 inch PVC coupling in the video at 6:16. It's larger than 1 inch. The reason its not a 1 inch is because a 1 inch won't work.

[@totallyfrozen]

1-1/2” ID

[@el1216]

1 1/4” pvc works

[@albertobu]

It is a 1 inch coupling.

[@el1216]

Use 1 1/4” pvc, not 1” (or 1 1/2” as one poster stated)

[@datboispicyg1708]

This is not how you replace a seal on an IntelliFlo, you can’t put a wrench on the motor shaft.
