Can anyone tell me the difference between a backflow preventer and a check valve? Don't they both do the same thing? A check valve is a lot cheaper though. I need a backflow preventer on my supply line, and thought I could just use a check valve instead.
Also does anyone have recommendations on what size circulators to use. I need one for the EKO 40 and one for the 4 zones. I'm using Taco ECV zone valves for the zones. My start-up kit came with a Taco 007-F5.
