maximum water pressure allowable

[jpaskell]

I recently purchased a 2013 Coachmen 30 RLS. Anyone know the maximum allowable water pressure? I have a 40 - 50 psi regulator that came with the trailer from the dealer. Pressure a bit low for my shower needs. Old rv unit had a 55 - 60 which was great. Not sure I can use that one but I think it would be O.K. from some of the threads I've read.*

Anyone have any Information that may help? Ideas would be greatly appreciated or a thread that gives me more definite allowable pressure.

Thanks,

Jim

If you are using the simple inline regulator, those are notorious for sometimes reducing the flow rates down too low. You can buy ones made up from Watts household type regulators. They are bulkier but they work great, and would keep you in that 40-ish psi range.

But if your RV can take 55 psi like you are asking, I know there is a Valterra RV inline one for that psi.

If pressure only low for shower, a lot of people change shower head to an Oxygenic which makes all the difference......I have. You can use your old regulator 55-60 also.

X2 - Oxygenic head rocks.
I have been rving for over 30 years and got one installed last year.
Never go back to the OEM head.
Want to buy my OEM shower head and hose?

I have asked that question to FR, They said 65 max. The fitting and pipe will hold way above that PSI. What happens at above 65 is it will blow your faucets off. The RV faucets are held in with o rings only that is the weak point. They told me if I wanted to I should change all mine out to house hold style and it would hold any pressure @ a CG. You house pressure should be higher then 65 PSI. It is probably at 90 PSI. call your Town or city and ask what is the water pressure they supply, unless you have a well and set your own.

The first thing I'd do is either connect the potable water hose directly to the city water bib without the pressure regulator installed and see what kind of pressure you get at the shower. Alternatively, if it's convenient, you could run your water pump (with water in the tank, of course) to see how your shower works on "internal" water pressure.
It may well be your lack of pressure at the shower is caused by manufacturing debris in the line forming a partial clog.

Once you establish that the shower works to your liking, then install a pressure regulator set for no more than 60 psi, since you were happy with that pressure before.

From personal experience I find the toilet will not hold back pressure much above 40 psi. It leaks and eventually will fill the black tank if pressure is not regulated.

I would think you need to check your water valve on the toilet.
It way have a weak spring and not seating well if you have a slow leak there.
Checking and replacement isn't a big deal.

I would love to have 65psi. I am closer to 50psi and that is after installation of the new district water tank. I would hate to be the people at the top of the hill with booster pumps.

Thanks to all that replied. Sounds like I will be O.K. with my old regulator. I will look into the oxygenic shower head, however. Sounds like a lot of folks find this thing "the way to go". Camping world has an Internet special on these for $25.00.

Thanks again to everyone, releives the worries about a 60 psi regulator.

HAPPY HOLIDAYS to everyone..

We installed an oxygenics shower head a couple of months ago and wow what a difference. I also install a regulator with a higher flow rate but the shower head was the key to more water feel from the shower head. All of the faucets flowed good before and after the water regulator. The shower head is pricey but worth it. I only run 50 psi on my unit. Shower head about fifty bucks.

Our Sunseeker often has pressure near 150 psig and I have had no problems. When the water system is closed and the water heats up, the water expands and the water heater relief valve drips. Pressure relief valves are rated to open at the set pressure but will normally begin to leak at about 95% of the rated set point.

One problem that I have is that I can't open the toilet valve when the system is under high pressure. I have to first crack the sink faucet to relieve the pressure.

Once I could not remove the water filter canister while dewinterizing the coach. I had flushed and filled it the previous day. I don't remember why I didn't install the filter then, but I forgot that the water heater was turned on and when I tried to take the water filter canister off it had built up so much pressure that I couldn't turn the canister.

I try to keep an air pocket in the water heater that's supposed to allow enough expansion, but it seems to fairly quickly go away.
