THe campground I usually winter at YOU NEED a regulator. Well they (one year at least) hit the lines with way too much Chlorine and even a month later I could taste it.. So I got the bright idea to fill the on board and let it sit for a few minutes... BIG IMPROVEMENT!!!

And I"ve done it that way ever since.

THe parks I summer at.. Well one the water is rather "Gritty" due to a lot of sand in it. So I only use water from the other park. Same plan. Fill up when I pull in, and when I leave. THe only "Fly" in this is when I next fill... It will be SC water not MI water. So I may have a few days of... Rapid Travel.

Personally would spent the few extra bucks for "QUALITY" Watts PR.

I got my Watts adjustable from Lowes. Check for 3/4 pass thru for good flow.

I will talk about 4 different Reducer products here
Small 3/4 inch (About) Cylinders (1) (Standard) JUNK
Small 3/4 Inch (about) Cylinders (2) With wings or colored plastic grips on the female end (high flow) Junk
Valterra adjustable (with or w/o gauge) supposed to be good. I have never tested
SUR FLO (A Watts corporation) Standard on many RV's I give it a 9 on a scale of 10
Watts or Zurin "Whole house" mine are both 3/4 inch NOTE this is when new.

I hooked up my zurin and the up-side pressore was 100 PSI or more. adjusted to 50 PSI. STATIC. then I opened a shower FULL FLOW and that needle acted like it was welded to the 50 mark. Same for Watts when new. over a decade the rubber inside the thing gets stiff and you need to rebuild it

These units have a bell shaped upper housing .. The bolt that would hold a real bell to the yoke.. That is the pressure adjustment. About 60 bucks with hose adapters. NONE BETTER.

Thanks for your replies. Hopefully we will not be needing it in weather where it will freeze. We would dry camp in those temps.

Another vote for the Watts. If potential for freezing, I put it inside the wet bay (heated) and risk losing the heated hose to excess pressure...

when we purchased our current MH in 2015 we made a ton of custom changes including the fresh water delivery system. we added a power hose reel permanently connected the 25' of hose to the internal plumbing. all i need do now is pull out enough hose to connect to the hose bib (we carry an extra 25'). we also mounted two Watts devices in the wet bay. the first is just a simple pressure gauge to show the unregulated inbound water pressure and a stainless steel oil filled adjustable pressure regulator.

but the cheap ones don’t reduce the pressure, just the flow. do yourself a favor and buy a quality Watts water pressure regulator. check your favorite home improvement store ir online at The RV Water Filter Store.

Yup! And while there buy some QUALITY water hoses that will never need replacing. They coil in cold weather easily.

Another vote for the Watts. If potential for freezing, I put it inside the wet bay (heated) and risk losing the heated hose to excess pressure. Has not happened so far. Had a Valterra regulator with gauge before. Does regulate pressure but restricts flow more that the Watts does.

I learned the hard way that the expensive Watts regulators and their gauges can be damaged if it is left out in freezing weather. Even though I disconnected mine and just left it outside it ruined the gauge.
