I was having issues with our fresh water tank filling up, so I reinstalled an old regulator I had laying around. It was installed originally on our rig.
After re-installing the POS, the water pressure plummeted so far that we couldn't use the shower without using the water pump.
I ordered this one from Amazon: Valterra Stainless Water Regulator
for $25.00 after reading reviews from other owners.
I installed it today and I have to tell you that it is the best 25 bucks I ve spent on this old coach in quite some time.
Our water pressure is fantastic, no need for using the pump what so ever for anything. If anything, it seemed to increase
the pressure from before I reinstalled the POS regulator a few weeks ago.
I'd rate it a 10.
