Are water pressure valves that control the amount of pressure on the interior water supply lines desirable? If yes, should it be placed on the faucet or on the inlet up on the coach. I was told by the dealer to hook it to the faucet, but that does not take into account added pressure from the water/hose created on a hot sunny day. Therefore would it not be better to attach it to the inlet on the coach?

At the very least use a flow restrictor at the water faucet near the power pedestal. The best setup is an adjustable regulator. Like this:

Hi and welcome to the forum!

YES, pressure regulators are desirable and I think your dealer gave you good advice to attach it to the faucet. If it were attached to the coach (at the coach side of the hose) your hose would be exposed to the higher pressures the regulator is designed to protect against and the scenario you describe would be even worse.

If you use our search feature, you'll find a lot of discussion on the topic of regulators. You'll find that many of us gave up on the $10 Camping World versions because they are really more restrictors than regulators and can can reduce the amount and pressure of water available in the rig.

Whole house adjustable regulators such as those made by Watts (and available at Home Depot for about $60) allow you to limit the pressure to 50/60 lbs without limiting flow significantly.

Best of luck.

RickO said it right.

Mine is mounted at the inlet valve of the coach.

It's very important to have and use one. I've measured water pressure at lots of RV parks and have seen over 100 pounds more than once.

I always turn off the water at the campground faucet when we leave the coach to go somewhere. Long story........just as we always retract the awning when we leave for the day......another long story.

I was also tired of the cheapies and after researching this it seems like the popular one is a Watts N55BG at rv water filter store. heres a link www.rvwaterfilterstore.com/PressureRegulators.htm

They are called Pressure Regulators and yes, they are to be desired/used, HOWEVER a short discourse on them:

Standard, Brass or plastic, cylinder about the diamater of a FEMALE hoee connector, one end is such a connector, the other end is a male, about 4-5" long: Recommendation: Leave on shelf or hook in store, DO NOT BUY. Reason: These do not have the capacity for anything more demanding than making coffee. And that includes washing the cup.

High Capacity: Same as above but either a bright plastic grip on the female end or "Wings" If it's a Camco. Much better than above. But same recommendation, They ALMOST have enough capacity.

Sur-Flo This Watts product is often installed as part of the City Water Inlet on Motor homes, This is the MINIMUM capacity for taking a shower in your motor home.

Watts "Whole House" 1/2 inch or larger inlet and outlet with hose adapters: RECOMMENDED. I believe Valterra makes one like it, same recommendation.

These brass units have a bell shaped top housing with a bolt and nut sticking up. This allows pressure adjustment. Very good and have the capacity needed.

NOTE: If you use a water filter.. You might want two of 'em.

I have one set to 60 PSI at the hydrant (Which can break 100 here) and a Sur-Flo at the inlet. (post filter) Reason: Many filters also restrict flow, the higher the inlet pressure, the less you will notice that restriction.

Any RV product that claims it is a Water Pressure Regulator in reality it is NOT. And it doesn't matter whether it has been attached to the coach at the time of manufacture or an aftermarket unit.

What I call all of them are Water Restrictors because that's all they do. They do NOT reduce the actual water pressure.

The only one that I would recommend is made by Watts. You can choose one that works for you from the following web site. They have a variety of styles and prices.

RV Water Filter Store: Standard Filter Canisters for Whole RV

I chose the whole house style and size as the coach is R HOME.

Also, since this is a potable water use item, be sure and get a "lead free" model.

What do you mean by 'capacity'? I don't understand your post at all.

Arch Hoagland · 03-22-2012, 10:57 AM

On a side note.....I have a water pressure meter I leave attached to a faucet in my water bay that's for cleaning out my tanks so I know what the pressure is all the time.

Arch Hoagland · 03-22-2012, 11:02 AM

hamguy..... The capacity means what the GPH is.

For example a low capacity might let you fill a water pail in 1 minute whereas a high capacity would let you fill that same pail in 20 seconds.

Kinda like a 1/2" water hose compared to a 3/4" water hose. More water out of the larger one for the same amount of time.
