  • proper backflow device for pool fill.

    I'm doing a piping remodel on one of our school's pools. Besides running new supply and return piping for the skimmers I have to run a new auto pool fill. The Director of school maintenace thinks a simple vacuum breaker can be used to separate the domestic water from the auto pool filler. I'm thinking a Zurn double check backflow is the correct one. What are your guys take on it?

    This is what we would use here. Maybe the rules are more relaxed where you are though.

          Thanks for the info. Zurn is made locally here so that is what is most available. I'll pick up a RPBV next week.

            The pools I've seen around here typically have the autofill device dumping into a receptor with a 2" airgap, seems pretty bulletproof to me as there is no need for the fill line to be pressurized, this is of course assuming the pump room is above the pool.

              I agree, a physical air gap would be best if you can work it in. It would be excellent protection at zero maintenance.

                In our area the air gap has to be inspected by a licensed backflow tester annually, I think they're afraid the air gap will get altered after the inspection.

                No, it's not rocket science, it's plumbing and unlike rocket science it requires a license.

                  Thanks (Button) They don't do that here but it makes sense, and I wish they did...
