max water pressure

[gserve]

Does anyone know the max water pressure allowed with the plumbing in my RV ? 2014 Rockwood mini lite 2502s

Most systems 50 to 55 max. Did you check your owners handbook? They say some for 60. But I gauge mine down to 45 to 50. Hope this helps

Lowest fitting rating I've seen is 100 psi, most are 125. Manuf recommend 60 psi, reducers for hose inlet are 40-50 psi which may be low for some people based on piping layout. Pex piping is way up there near 200 cold. Best follow the mfg and max out at 60 psi or less.

The problem is not your plumbing, it can hold the pressure. It is the cheap plastic fixtures. They are not the same as your home. They are mostly held together with O rings and will blow at 65 PSI. If you changed them to household type you wouldn't have a problem the pex is strong enough. Same as the hoses that connect to your water pump. Same hose as you buy at the stores. the same hose as you connect to your city water. then it go's to pex. The shower and bathroom sink are the worst, they will blow first. The weak point of the pex is at the Tee's with the clamp fittings, but still that is not the real problem. You really need to stay between 45 and max 55 psi. and that's because of the fixtures.

Use a regulator whenever you hook up to a city water supply. They're cheap and you won't have to worry about pressure.

Good adjustable full flow regulators like watts with a gauge are not cheap, but are worth it.

This new one may be an exception for those who don't need adjustable or with a gauge.

NEW PRODUCT!! Fairview 55 psi inline regulator with great flow. This is what everybody has been waiting years for. Expect little difference from what the spigot can put out. Not adjustable or repairable like the Watts units, but very economical with high performance for those not willing to go with the more expensive units.$24.95

Know, I have been. Do you need to replace them after a while? The one I have is over 7 years old.

The cheap one just have an orifice that reduces pressure and flow, and they may become clogged or reduced in flow more than normal, but if it is working for you, why worry.
