Pond Boss Forums AERATION Systems questions Check valves

Also if you have the compresor on a timer where it is on & off each day, an engineer at GAST (compresor mfg) told me that it is important for extending the life of the compressor not to have to push water out of the air line each time it restarts. Some uses place a check valve at the diffuser and at the pump.

Pressue relief valves are also imperative during blockages in the air line.
