Water pressure?

The campground has warned you. Heed the warning. Use your fresh water tank.

PEX Temp/Press Ratings

160 psi at 73°F
100 psi at 180°F
80 psi at 200°F

Note: As temp increases pressure decreases

Water heaters....
Normal Hot water temp is 130*F/140*F depending on Brand
Hi Temp T-stat...open at 170*F/180*F depending on Brand
T&P Relief Valves...Open at 210*F/150 psi

So for safe operations....
Pressure Regulator set at 65 psi MAX (static pressure---no flow)


After having a fitting break while on city water using a Watts Reg set for 50# and flooding which resulted in $6000 in repairs/costs I use nothing BUT pump/fresh water tank
Pumps can be quieted but I prefer to hear it run...cause if it is running W/O demand then I KNOW there is a LEAK

QUALITY adjustable WATTS regulator set to 60psi GOLDEN.

RVs are supposed to be tested to 100 psi at the factory by RVIA standards or NFPA 1192. Can't remember which. Doesn't matter much though, because as mentioned above, it's only as good as the connections done at the factory, and some are NOT done well. I found a leaking PEX tee behind the shower last summer. The cinch clamp hadn't been tightened properly. Not only that, they used the wrong fitting to convert from PEX to the braided vinyl hose for the toilet.

We have a Watts 263A regulator set at 65 psi. I mounted it inside under the kitchen sink. Has a good flow rate, unlike the inline ones. We have seen as high as 140 psi in a CG and have heard some reports as high as 200 psi.

A pressure gauge is good to have too. If you find that your faucets are only putting out a dribble, it's nice to be able to quickly tell if it's the CG pressure that is low.

Oh, and the better regulators can be rebuilt. The inline ones can't be and sometimes plug up due to the small orifice inside.

I know I'm weird but don't like hearing the pump work. I'll get the regulator and use my inline filter. Those 2 things should keep the pressure in a safe zone, I would think.

I think the pex itself is good for around 100, but the elbows, fittings, and fasteners about 60, if all in good condition. I just fill the tank most times, rather than hook up a city hose. At least then, any little leak can be detected. My pump gives good pressure, around 50 psi. Pressure at shower is good, using just the pump.

x2 on an adjustable regulator!

They can rate the water system whatever they want, but the pipes and hoses are thrown together in a crude fashion. I would get a regulator and adjust it to under 50 psi, even then you want to regularly look for leaks.

40 to 50 is safe. 60 causes my rig to leak. I think you're safer using your tank and pump.
