Water Pressure Regulator

I still have a lot of questions so please be patient with me. I am a sponge for knowledge on the Alpine I just purchased. When connecting to water do I need to install a pressure regulator?

Thanks

Here's what I did.

Pressure Regulator Install



Here it is at work.



The Valterra adjustable regulator is available at many RV supply stores.

I added the Norgren gauge to observe the incoming pressure from the park spigot.

FWIW

I had the Valterra regulator. It wasn't robust and began leaking after a few months of use. I replaced it with a Watts household regulator.

Do I need to install a pressure regulator?

Most motor homes are labeled something like 45 (or 50) PSI max on the city water inlet... Now I have two parks I stay at in the summer, both are 55 PSI or less on the water mains.

The reason for this is not the danger of blowing pipes but some of the valve seals epically in some toilets, are only rated for 60 PSI test pressure (That is they blow if you exceed 60 PSI so you want to stay 50 or less in those rigs least bad things happen (Flooded bathroom).

When I had a sticks and bricks the city delived 80 PSI, way above what the safety zone.

The park I'm at now has measured 120 PSI and I've measured over 100 myself.

One person mentioned a park he was in where the park measured ONE HUNDRED SIXTY FIVE psi.

Here, we have had hoses blow apart due to the pressure. So you put a regulator as the FIRST THING coming off the faucet.

I actually have a bunch of them. one (my primary) needs repair just now (It froze when a heater failed, will fix next week, Do not need today since I have controlled pressure by a different method (TURNED IT OFF). It is a Watts 3/4 inch (Easier to screw hose adapters into) 1/2 inch or larger will work fine.. So will a Valterra, the adjustable model with gauge.

My seondary regulator (more on this in a second) is a Sur-Flo.

My opinion of many regulators.

Standard, 3/4" Cylinder, brass or plastic male and female hose ends, non adjustable.. NOT ENOUGH FLOW openings internally are too small. *3*

HIGH FLOW,, like the above but the Camco version has "Wings) It is blue plastic) most other makes have a brightly colored plastic grip on the female end... not much better, still not enough flow. *5*

Sur-Flow,, I give it a 9

The big Watts.. 10+

On the standard scale of 10.

Why 2 Regulators (primary and secondary).

If you use a commercially made water filter (I used to) they too restrict the flow. The primary in this case can be set high, 60-80 PSI, it feeds the filter.. AND the extra pressure (When the park supplies it) pushes water on through.

The secondary is on the filter outlet and protects the rig.

As it stands.. The secondary is now a "Spare" in my rig.

It is hard to add much to the above very comprehensive answer. In my experience parks with high water pressure will tell you when you check in and advise you to use a regulator. Most parks I visit have low water pressure and using a regulator reduces water flow too much so I don't normally use one.

always good to have one installed. as not all parks will have a moderate psi.
