Cause for Polaris backup valve not cycling

Hi gang,
Glad to have found this forum! I could certainly use the help. My Polaris 280 backup valve was not cycling -- it was outputting a constant stream of water, all the time. So I assumed it was bad and bought a brand new one. Guess what? The new one does exactly the same thing.

Tons of hits on "polaris backup valve not cycling," but they all say to make sure the valve IS cycling, but nothing about what may be the cause for one that is NOT cycling.

Any help you can provide would be greatly appreciated. Thanks in advance,
Terry

Forgot to mention, in case it matters we have a main pump and a dedicated pool cleaner pump.

Hi, and welcome to the forum!!

I have a Polaris 380, and the only time I experienced the steady stream of water from the backup valve, a new one fixed the problem. It only takes a tny crack to cause a problem--have you inspected the new one to make sure it wasn"t alreadycracked or damaged in some way when you bought it?

Hi Janet,
It came in a factory sealed bag, packaged well in the shipping box with plenty of air packing. I can't imagine it was already broken. I'm wondering if it could be a pressure thing, as in too much pressure? I don't know how to check for that. Still searching ...

I would think that if pressure were the problem, it would neverhave worked correctly in the first place. Have you tried calling Polaris and see what they suggest? I'll be interested to hear what the issue is....
