The diffuser in the attached photo is part of an effluent sand filter. The filter has a filter plate into which the diffuser is attached so that the diffusers are the only means by which water can get from one side of the filter plate to the other. The sand and anthracite sit on the filter plate with a chamber underneath. The water goes down through the sand and anthracite media and somehow goes through the diffuser to get under the plate to drain out through the chamber, backwards through the backwash pumps. The backwash pumps pump water into the chamber under the plate and water for backwash comes up through the diffusers. A blower also blows air into the chamber under the plate and air also comes out of the diffusers agitation. So this diffuser is supposed to let water and air go up, and filtered water go down, but strain out the sand. Sounds ambitious to me and I don't know that this thing has ever worked.
1. Where could I get some new ones of these?
2. Is there a better designed diffuser that does the same thing that we could replace these with?
