Water pressure and volume suggestion

Hi there everyone,

DW and I live in a 2003 Allegro bus. We have been struggling with water Volume ever since we put a pressure regulator on. At the holding tank for the RV park, the gauge says 50 to 55 PSI. Below 50, the compressor kicks in and increases the pressure to 55. We've tried two different styles of 'Campco' pressure gauges and they both say the pressure is between 75 and 80 PSI without a regulator.

We are wondering if anyone has any suggestion for an accurate way to measure the water pressure at our rig? when we put a 'Pressure Regulator' in the water line, though the pressure comes down to at or below 50 PSI on the Campco gauges, the volume is almost not enough to keep the shower valve diverted when we take a shower in the morning. I was thinking of maybe making a 'Pressure Vessel' to go between the RV and the faucet, but fluid dynamics is not my strong suit.

We'd welcome anyting that anyone can share with us.

Thank you very much to anyone for your help!

Respectfully,

Eric and Carol Anderson

If you are talking about one of the camco regulators like this:

Camco Brass Water Pressure Regulator with Gauge - Walmart.com

You problem is probably the regulator. You want something like a Watts that is adjustable and has a guaranteed flow. You are probably looking at $50-100.

FWIW why not just keep water in your tank and use your pump instead. That way you have a constant setup for pressure and limited damage if there is a leak.

If you are using one of those little inline regulators my guess is that's your problem.
A little more money, but a good Adjustable Regulator will give you full volume at set pressure. There are other makes but I use this one and it does the job well.

Water pressure and volume suggestion

X2 on nothermark and Dennis. Those fixed Camco "regulators" are primarily big time flow restrictors. You need either a Valterra 1117 or a Watts 263. Both are good quality adjustable residential pressure regulators that allow a good robust flow.

These guys have the right idea. Those inline pressure reducers greatly reduce volume, just look inside it and see how small the holes is. I bought a home regulator and screwed hose ends onto it. It also had a gauge port that I put a pressure gauge in. It's adjustable too I set it at 45 lbs. there is a place online called rvwaterfilterstore.com that sells them already setup for RV's, they range from $25-$100. I'm not affiliated with them but they are only place I have found that sells them already set up for what we need as RV owners, there may be others though.

I think I would first get a better understanding the pressure at the RV. If the system is regulated at 55 psi, ow the devil are you seeing 75-80 at the coach? Are you at the bottom of a substantial hill with respect to the source?

But given that the 75 psi is accurate, the right answer is as above: get a decent quality "whole house" regulator from Watts, Wilkins, etc. (available at most hardware or home stores). Most of those will need adapters for hose thread fittings, but that's only a few dollars more.

This is what we use. I think I paid $55 for it.

I wouldn't worry too much about the hose, it's the interior plumbing you need to worry about.

I once had a hose look like a snake that ate a large meal and spraying a pinhole size stream of water. I had mounted the regulator in the wet bay putting the hose at the mercy of the unknown pressure. I moved the regulator to the hose bib after that. Nobody has stolen my regulator since I've been rv'ing but I do wonder from time to time about my poor regulator left to fend for itself.

Water pressure and volume suggestion

Another mistake I see often is people using a 1/2 inch hose. That will make a significant reduction in volume versus. 5/8 inch hose. Combine the small hose and a cheap pressure regulator and low volume is almost guaranteed.

I just replaced an old Valterra with a Watts 263. It seems to work well with better flow than the old one (just wouldn't adjust anymore). The link below had what I needed, and quick shipping.
