water pressure regulator

[realtor56]

Have a 2017 Georgetown XL369 class A and when I put the water pressure regulator on the incoming hose the water pressure drops so low I don't get enough pressure to flush the front toilet. Does anyone know what pressure I can have without damaging the water system? Could it be a faulty cheap regulator? I'm in a RV campsite, when I take off the pressure regulator the pressure is great. Thanks...

45 psi is ideal. Is tested higher, but 45-50 is what you want.

You can get adjustable regulators with gauges at Amazon.

Do yourself a favor and buy a Watts pressure regulator from http://rvwaterfilterstore.com/. They don't limit flow like the cheap $10-15 ones do.

Following a recommendation from another forum member I got when experiencing the same issue. Couldn't get the pressure right - it was always either too high or too low. So now, I run camp water thru my filter setup into my fresh water tank. Use the RV's water pump - gives perfect water pressure. I just top off the water every couple days.

I have had the cheap brass regulators that had almost water flow that I had to throw away. Just got a Santu that I am excited to try out. Here's the link. https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1

I've had one for a couple of years, and wouldn't leave home without it.

Plumber here... the pipes and fittings on these RVs are the same exact stuff in homes. They can handle up to around 130psi. The week points are the faucets themselves and the connections they use which are plastic. But you’ll be fine up to around 80psi. Buy a water pressure gauge and test the park pressure before hooking up to it and if your lower than 80psi there’s no need to even put a regulator on.

I've had several of them fail and fortunately they have all failed closed. I haven't been able to prove it but I suspect it's from rocks and debris in the water supply. Check the aerator screen in your kitchen sink after a couple of years of use and you might be surprised.

I don't know if anything short of a commercial type regulator could stand up to that. On the other hand that's a lot of hardware to hang off of the parks hose bib and if it's mounted at the coach you're not protecting the hose from the supply.

At ten bucks a pop I just carry a spare. On the third hand, I've picked up several at public campgrounds after the weekenders leave.

Chris, I believe you are correct. They test units at 80 during the assembly process, but recommend running 45-50.

At 50, you have plenty of pressure to run everything. Why could I want it higher? Always like to learn.

In SoCal the average house runs at about 65-70 psi so obviously a home at lets say 2000 square feet you’d need that much psi. Now a rv at lets say 250 square feet 50psi is more than enough. The bigger issue is the these cheap regulators that most RVers have, not only lower pressure but limit volume which really kills the feel of the pressure. I made a home pressure regulator that connects at the parks bib and the hose on the other side and have it set at 65psi. Great pressure and volume in the rv.
