Back wall in deepend. The three capped PVC pipes on the deck in the rocks were about 15 inches high connected to a air filter, all positioned under the diving board my insurance company made me take out. Each set of 4 jets has its own control valve at the pumping station. my signature has what I'm putting in, this week. Anybody want to take a stab at why you would but 8 jets so close to each other on a 40ft pool???
