Is there a best float valve for autofill?

[tomas21]

Is there a preferred 3/8" float valve that works without subtle hiss/fill never fully closing? Using a MP Industries autofill.

Tried the Stetson Development Inc Pool Pond Spa Water Leveler PVC Auto Fill 3/8" Float Valve but after a couple months doesn't fully shut off even after multiple adjustments.

Curious what others have success with when replacements….

That is the same one I use and haven't had much issue with it although I have had to replace it every couple of years. I did need to clean it once to make sure there was a good seal. Have you inspected the rubber seal? It make have deteriorated for some reason. A little pool lube on the rubber seal might help.

Remove the cotter pin and check out the white rubber seal that sits against inside hole when closed? Looked ok

Also check the hole that the valve sits against, that can get some debris in it and prevent the rubber piece from full contact. Also, make sure it is smooth and not marred in any way. Any defect can prevent sealing.
