I mean back-flow preventor, same thing as a check valve. Yes, I would use the Apex to sense the pump failure, so it could turn on the back up pump. I was thinking the check valves would be at the inlet , just because of the way the two pumps plumbed together. I was thinking that I had to have the check valves at the inlet side, but the more I think about it, the outlet side makes more sense. I just worry about stagnant water in one of the pumps getting into the tank. |
