After months of searching i finally laid my hands on a nice watts unit, full flow and "love that chicken at popeyes" (no shower flow drop offs when the toilet is flushed
anywho, after three days of piece parts and back and forth to lowes ,
i think i may start making kits, up so folks can get one without all odd attention you get at lowes going back and forth from three rows of plumbing parts to get what you need
i ran a test all week at 70psi on the rv and had zero leakages and great shower flow, then when i installed the regulator i dropped it to 58psi and still have superb shower pressure and flow and also enough pressure to shut off the r/o unit when its full, instead of the drip drip drip
i put this thing together to allow easy winterizing (draining) and quick connects at the supply side,
the panel that has the winterizing nonsense on it also removes to allow me access to the gray tank flusher i installed earlier.
