Pond Boss Forums AERATION Systems questions help tweaking current aeration system

The Vertex diffusers need 1/2 psi to open. They have a backflow valve built into them.

We typically use 1" poly line when running to a manifold box, but do the calcs if running a long distance to see if it needs to be upsized. We used 2" at one pond because the electric was 1/2 mile from the pond.......

Vertex uses ball valves in all their manifolds and I've never had a problem balancing out the flow to each diffuser.

Good idea on using a dump valve to bleed off excess pressure for the winter. I have a remote manifold box at my pond and have an extra ball valve in it to do just that for the winter.
