Check Valve Help!

[TazJMT]

I don't think the back flow from the feeder would be damaging to most filters.

Oh-well then I have to ask-why in the world was it suggested by so many people that I use one if the chlorinated backflow water wouldn't do damage? That's frustrating!

It destroys heaters and any equipment with metal such as a gate valve. It would probably damage an SWCG.

I personally never used check valves when I installed feeders years ago. BUT, in this market pumps usually run 24/7 (afternoon thunderstorms mess pools up on a daily basis), and it wasn't usually an issue.

SWCG? Whats that

Salt Water Chlorine Generator.

SWG is more common, but those devices do NOT generate salt water, so I kinda banned that term here, among the mods.
