Water pressure regulators

I have the el cheapo pressure regulator and my water flow inside the trailer isn't adequate for either the inside or outside showers. I was thinking of spending the money for an adjustable regulator.
Would one of these Amazon.com: Valterra A01-1117VP Brass Lead-Free Adjustable Water Regulator: Automotive
do the job of increasing the water flow?

Hi Teach!

That's the regulator that we use. It doesn't seem to affect the flow very much. The Amazon price is also $12.00 cheaper than CW. FWIW, CW does sell a high-flow regulator. It is much less expensive, than the adjustable.

Clicky...

Hi Teach,

Before that one came out by Camco, I created one similar out of parts form Lowes.

This one, http://www.lowes.com/pd_368035-18701-LFN45BM1-U+3/4_0__?productId=3503148&Ntt=watts+pressure&pl=1§tU RL=%3FNtt%3Dwatts%2Bpressure&facetInfo=

That Watts regulator has no issues with flow. It is bigger capacity then anything I would ever be able to flow in the camper. I had to buy adapter fittings, a tee and a gauge. The end result cost was a little more then the one you linked. If you want a pic of the setup, let me know I'll dig one up.

I tried to find any kind of spec sheet on the Camco to compare the compare flow rate, but I cannot locate anything on the web.

The Watts one I have is here under Specifications: LFN45B Lead Free* Water Pressure Reducing Valves , Water Pressure Reducing Valves - Standard Capacity, Water Safety & Flow Control - Watts

That said, I agree the one you are looking for is a better actual regulator then the restricter types which are for all practical purposes, a flow restricter which drops pressure, not a regulator. It will be better then you have now and will actually regulate to the same pressure in the camper with regardless if you are hooked to 50psi, 60 to 80 pis incoming pressure.

Hope this helps

John

I'm looking at this Valterra unit.

Valterra (A01-1122VP) Lead-Free Water Regulator Price:$17.95



According to most of the comments, it seems to regulate at 55 psi, plus or minus. That's around 10 psi higher than the low end Camco regulator. Is this an acceptable level for an '03 Sunliner? Many of the comments mention that it is for newer RV's but no one says how new.

As far as pressure, your 2003 has PEX tubing good to 150psi as is the setting for the safety relief valve in the hot water heater. Which is good it will not burst until over that pressure, however the rubber compression washers used in this vintage PEX could handle that pressure when new. As they get older it is questionable as they become more brittle. Every now and then I have to tighten a fitting due to either vibration from towing or age of the rubber.

If you get a real 55 psi, it will not harm the system just be aware any pressure higher then your "normal" use to be, can sometimes create a drip at a weak fitting. All it needs is a few psi more then it use to and a drip will start. You really cannot do a lot for it until it starts, other then checking for loose fittings, but again just be aware at all times.

These types of re-stricter pressure reducers are not the stablest regulators, meaning the water will fluctuate more in pressure, but they do help protect the camper. The regulators with a spring and diaphragm hold pressure stable much better and they cost at least twice as much most times.

The one you picked will work. Just the spring type work better.

Hope this helps

John

We have both, the cheaper and the more expensive (the cheaper first). Under high pressures, the cheaper unit shuts the pressure to a trickle. I don't know if it was a malfunction or expected under very high pressures. We have been to some campsites with a LOT of pressure. Our house pressure is 60 PSI and we have seen what I estimate to be much higher than that (maybe not double, but much, much higher). We have had a sink fitting failure in one case when not using a regulator.

I have not used the newer "better" much and not under such extreme pressures.
