I have an alita pump that can run 24 airstones but if I put one of those cheap plastic check valves on it barely any air will flow through. The back pressure will be bad for a diaphragm pump too. I don't use a check valve because of this, have not found a good cheap one. The swagelock check valves would be great but would be expensive to buy 24 of them.
