20 bottles, 1" main lines, 3/4" feeds, and 1/2" risers with 1/8" washers to create a spray. All CPVC. 2700 GPH dirty water pump is WAY overkill. Even with a 3/4" divert line the spray is more than adequate, even without the 1/8" constrictor to create the spray. The Oxiclean TSP mix is foaming quite a bit, but not a problem.
