Water Pressure

After experiencing fluctuating water flow at a CG recently, I have ordered a water pressure gauge/regulator. What pressure range is safe when hooked to city water?

Most RV water regulators are set around 45 PSI.

I've seen water pressure regulators anywhere from 40-60PSI. The adjustable ones with the guage let you know exactly where you are at. Remember to put the regulator at the spigot...before your hose leading into the trailer. This way, it not only protects your trailer plumbing....but the hose also.

these modern a/s units are tested up to 90 psi?

and operational at 60 psi.

i agree IF you are gonna use a second reg, install pre hose.

the problem with using 2 regulators is that they can sometimes compete...

resulting in REALLY choppy, water-hammer like flow.

i tried two and couldn't get any smooth flow, with a short hose, and no filter.

the simplest way (4me) to reduce fresh water forces into the trailer is with a cartridge filter outside and a narrower gauge hose...

then IF there is a need for higher flow, just flip on the pump and cycle the tank water.

using pump and shore water at same time

Question,

Does it hurt to run the pump for additional pressure when hooked up to regular shore tap water. Book says not to, but I see no problems.

thanks, richard

What would be the problem about getting water pressure from 2 sources? I had it done lot of times, as well as using the pump to boost the gravity pressure in Mexico.
Some high-end coaches have water supply going thru the tank/pump only. This way they always have the same pressure.

Don't newer Airstreams have a built-in water pressure reducer? (And if I'm right, does anyone know when AS started doing this?) I used to use one at the faucet with our previousl SOB motorhome, and I've tried it a few times with the AS but it felt like it reduced the water pressure too much.

RIGHT!

Most Prevost, Newell and a few other high-end MoHos do not use a city water inlet feed directly into the coach. They have an auto-fill valve on the city inlet that fills the on-board water tank. All water in the coach then comes from the coach's pump.....result is constant, consitent water pressure.

The built-in regulator on my '77 Excella 500 had 45 psi stamped on the tag hanging on it. I have been using an adjustable Watts regulator and have set it on 55 psi. I figure if the built-in regulator in my '86 fails or is set at 45 psi or higher then I am still safe.

My 1965 Safari has build in pressure regulator. I just tried it after about 25 years of non-operation. It is slowing down the pressure raise, but allows it go all the way up to the city pressure.
Can't keep everything original on 43 years old coach

I have heard of people who connect their water pressure regulator at the campground and when they find that the pressure is within an acceptable range, they pull the regulator off. That doesn't make sense to me because pressure in the line when checked may be low and later may be higher than you want it. If the built-in regulator is not working correctly and pressure rises then this is a recipe for a rather wet trailer. I connect the regulator straight off the spigot and leave it there. When I know that I will be away from the trailer for a period of time I also shut the water off at the spigot just in case.

Those RV-style in line regulators are garbage. I used them years ago and the pressure was never right. Putting them at the faucet with long garden hose helped, since the hose worked as a pressure accumulator, but that was just partial help.
Airstream is having copper plumbing, so has my vintage motorhome. At my residence city pressure is 120 psi, raising on the weekends to 150 psi. I have no problem running mine RV directly on that pressure, what makes for very good showers. The only occasional problem is, that water heater safety valve opens at 150 psi.
So I am using pressure regulators, but they are household regulators and I like them set to 80 psi.

Depends on which year model you are talking about. the newer ones (2006 on) state that you may use the internal pump and water to augment city water pressure.
