How To Replace Spider Gasket on Pentair Pool Filter Multiport Valve | Cedar Park Pool

[@gordonsmith4232]

I’m so glad I’m not the only one with loud ass frogs!!!

[@sergii_swimming_pools]

Thank you so much, finally video on this topic with no shaky camera and annoying voice rumbling!

[@1ebric]

Love the frogs, so relaxing

[@drgolfjim]

It was your video that enabled me to figure out the problem I had been having with my pentair multiport valve for over a year!! Thank you.

[@engineerable]

Nice! Was it a bad gasket?

[@colbyyounger4388]

I love how the old gasket just popped right out of there. I've never seen one do that, they usually have to be scraped out for an hour

[@engineerable]

That's what happens when using RTV silicone to glue it in versus cyanoacrylate super glue as recommended by manufacturer. However, the super glue does keep the gasket glued longer than the silicone.

You saved the start of my swimming season with this one chief thank you so much!

[@engineerable]

Great success!

[@annemariebechand6788]

Great video. Thanks for making it!

[@engineerable]

Glad to help!

May the force be with you

[@honkeyness9427]

What is the name of a gasket glue (?) that you recommend? Thanks

[@honkeyness9427]

Got it

[@engineerable]

I'd recommend super glue instead of the RTV silicone used in this video. The silicone adhesive doesn't last as long, but is a lot easier to cleanup. The adhesive sold for spider gaskets is a cyanoacrylate, which is super glue. It will last longer but is very difficult to scrape clean.

[@honkeyness9427]

@@engineerable Thank you. My gasket came out of the groove and got torn up. I’d hate to have scrape off super glue but maybe it’s what I need. Do you recommend re-lubing the top of the gasket yearly maybe?

Bravo 13 year pool vet

[@rcothron]

How long did you wait before you put the valve back in service?

[@engineerable]

You should wait about 24 hours.

[@crittrgittr]

Do you drain the filter or shut off external valves to prevent pool or hot-tub water from coming back up into housing once you 'pop the top'?

[@engineerable]

Yes, you need to do something to bring the water level below the valve, otherwise water keeps coming up as you try to replace the gasket.

[@bludika]

can you use a silicone caulk instead rated for bath/kitchen instead? it seems like a pain in the ass to always scrape the old adhesive off if using RTV

[@engineerable]

You will have to scrape some off no matter what. You can give it a try. Cyanoacrylate (Super glue) is the main recommended adhesive, but that seems very aggressive. The main thing the adhesive is doing is keeping the gasket in the slot when you lift the valve. Otherwise the gasket can stick to the valve and lift up with it.

[@Mvango1]

How soon after you put it back together can you turn the pump on?

[@engineerable]

The RTV silicone I used in the video had a cute time of 24 hours, so wait at least that long. If you use cyanoacrylate, it will cure within a few minutes, but it is much more difficult to remove.

[@gomezgarcia7609]

do you really need RTV? - seems original gasket was installed without ....#3 Phillips bit would help with bolt removal and replacement

[@engineerable]

If you don't glue in the gasket, it's likely to lift with the valve head when you change the settings. The gasket needs to be glued in somehow, and the manufacturer recommends super glue, but that is a pita to scrape out.

[@userbosco]

I was taught that prior to taking the valve cover off, you should depress, then turn the handle between two positions.

[@engineerable]

Good idea, same as you do for winterize

[@tdhoeffel]

Was it leaking from the top

[@engineerable]

Leaking from the top is a problem with the o-rings, either on the side or out of the valve stem. Watch this video: kzbin.info/www/bejne/hXynaYBrlNNqqas

[@mitchellunruh754]

I’ve been scraping this idiotic gasket for 3 hours already and begging for a different way to do it for my future self. I’ll try your blue glue, cant get worse than this stupid super glue.

[@engineerable]

Yes, any of those alternative glues will be better than super glue.

This has to be one of the worst how-to videos I've ever seen
