I do agree that a quality regulator like the Watts series is the best choice, but I'll also note that the "cheap ones" like the Camco barrel regulators, do indeed regulate the pressure properly. I've tested several of them using before and after gauges, and while they may not be as accurate as a Watts, they do get the job done they're supposed to do. If they simply reduced flow, there would be all sorts of complaints about them since the pressure would still reach the incoming line pressure when there was no flow, possibly blowing out fittings or hoses.

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.

B.O.

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.

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

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.

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

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.

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