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?
I am, just finished my 3 days of CEU's for renewal last week...

And I can accept a shot bored drain to a sanitary sewer (with a proper air gap) for an RP, if the elevation allows it. I can't accept relying on a sump though.
