O.K., I mesed-up on the nomenclature: DCVAs should have 8" of lower clearance, with 12" of gravel sump below., 8" clearance side to side. The RPs should have a "shot-bored" 1/4" per foot drain to a sanitary drain in case the relief valve goes. As I said earlier, with yearly testing and proper book keeping, there are no problems, as the checks and valves should be noted as ready for replacement way before they fail. I wonder how many of you are licensed testers?
