Water Pressure Reduction

Hello All,

Taking the Land Yacht out for our maiden camping trip this weekend. Been looking at the net for info on hooking up etc. My question is, is a pressure reducer needed for the fresh water line going to the camper? Thanks for your input!

Maybe?

My 1975 Sovereign has a built in pressure reducing valve, however I usually use one on the outside line just as a precaution, they aren't that expensive and are cheap insurance in my opinion.

I use a residential quality, adjustable regulator with pressure gauge. Got it here already fitted for RV use.

Camping World sells a unit for around $60 with pressure regulator and gage setup with male and female hose fittings.

If you have an older rig. A regulator is a good recommendation. A simple one works good.

To answer you question, yes it is needed, at least that is my opinion. My trailer comes with a built in one and is set to something like 60 lbs of pressure. More that than has the possibility of damaging your plumbing. So, if you were to hook up to a municipal system where the pressure is much higher than that, you could blow some pipes or some other such damage. I know that the pressure measured at my outside faucet at home is right at 75 pounds.

The regulator gives you peace of mind if nothing else. The external ones sound like a good fix.

When I re-plumbed our 1971, I used 1/2" PEX, a Kohler kitchen faucet and a Sandvik marine single handle shower valve. I used normal home components, which easily cope with 150+ psi. Next time I'm in the bottom of the closet doing plumbing, I'll likely pull the regulator - it really isn't needed with modern parts.

The old copper pipe was clearly capable of handling the same kinds of pressures, but perhaps the fixtures weren't capable of that.

I did the same thing as Bart's. All household plumbing fixtures except for the toilet. Have not had any problems.

Make sure that whatever pressure regulator you get that you put a gage down stream to see if it is working. I removed my old adjustable regulator and installed a new one. Both of them allowed the pressure to creep back to the supply pressure which defeats the whole purpose of having one. I bought one from Lowe's for about $30 and will be taking it back for the $70 one and see if that works.

The ones I posted above have a gauge mounted, but "downstream" of the regulation. IOO, the gauge reads regulated pressure. I do have another "diagnostic" gauge setup in the shop which I can use to verify readings periodically.

Check your Owners Manual, I believe the MH's have a built in regulator. I bought the type of regulator that has the pressure gauge right on it and the couple of times I tried to use it I had very low water pressure inside. I think it was because the water was being double regulated. When I removed it the water pressure was fine.

Pressure reg

The owners manual, now that's a novel idea. I'll look tomorrow. I did buy one and the pressure seems good, but I'll see what's recommended. Thanks!

Turns out it's built in (2005) so I recon I don't need one. Guess I'll keep her in the LY for emergency use or more likely a loaner at a campground. Thanks for the info!
