What have you double check folks been using for the flush test valves?  Got
a system with a 700ish demand no pump.  So I'm thinking the 2" main drain
isn't big enough.  Does someone make a FDC like thing with male threads?
Then I'd have a 4" BFV on the inside to control the flow?  Sound right?
Could I just straight pipe a 3" but then I'd have no way to put a hose
monster on?  Hose monster to dissipate flow as I don't think we need to
actually measure and record flow.
