check valve placement on 31' rear bath?
Hello all, just about to finish the new pex crimp job,but before i put it all together.......
On the rear bumper, i've got my city water hookup, then check valve, then drain, then distribution to lavs, HW heater, etc.
Uder the sink, i've got fresh water tank, then pump, THEN check valve, then drain, then distribution. Is this the proper order?
I read something saying to put check valve before pump, just wondering if it matters on the order there?
