Changing O rings on a Jandy 3 way valve

Changing O rings on a Jandy 3 way valve
Today I found a Jandy Stealth variable speed pool pump, that seemed to be sucking a lot of air. I quickly found the source of the problem being the Jandy 3-way valve right in front of the pump.
So we opened up the valve and changed the two stem o-rings on the valve.
Once that was complete the pump no longer sucked air. Pretty simple job to do you can do it as well.

This happens a lot. Glad I could film it for you.

Im a pool technician for over 17 years.
Good video and very important, the only thing I see wrong is the reinstalling of the screws, you are supposed to screw them one across from the other so that the valve goes down evenly.

Solid video, thanks. I visited Amazon for the o-ring kits on the Jandy valves... I'm also rebuilding my Hayward pump/impeller seals. Hopefully I'll eliminate the air entering my system. I replaced the large cartridge filter and that helped immensely with the filter pressure and pool flow but I was still seeing air get in... I suspect my old gray Jandy valve o-rings are worn, based on how neglected the filter cartridge looked. Learning as I go here in FL, retired from NY.

So helpful, I appreciate the time you took to make this for the novice DIYers such as myself!

my pool has been sucking air and not priming. I replace the pump, the filter. and it was still sucking air... not one person told me about this.... when I went to the pool store they said... make sure you check the check values too. Thanks for the instructions. CROSSING fingers that is the problem... I don't want to pay 300-500 for someone to come tell me something simple

If you have a Pentair valve - Pentair exploded diagram of their valve on their web site shows a small spacer that goes between the 2 small o-rings that go onto the shaft. I just did mine and sure enough, there is a spacer.

Great video. Replacing my o rings today.

Nice job! Is it possible for a problematic 3-way valve to allow sucking air in one position, but work fine in another position? My system is having troubles holding a consistent pressure and there are lots of air bubbles from the jets, BUT ONLY when diverter valve is not in skimmer position.

Does the Jandy have a plastic spacer between the shaft O-Rings like Pentair?

If my cover is not marked, how do know the correct orientation to reinstall it correctly?

[andybrody]

How did you determine that is what was wrong with this pool/system/plumbing?

[callmesunny]

I took the valve lid off and the screws stripped. Now they won't tighten. How do I fix that?
