I went to the RV water filter store online because I did not know what a watts regulator was. This statement was on their site.
Quote: Excessive pressure can cause your plumbing to leak or even rupture. It doesn't take long at high pressures to cause damage, even a fairly brief "spike" can do it. Pressure regulators are installed in your water supply line to limit the water pressure going into your RV. RV plumbing is normally rated at 125 psi, but you certainly don't need to use that much. However, 60-65 psi is a very comfortable pressure for faucets and showers. Parks don't always have that much, but when they do, having a regulator designed for good flow and pressure adjustability will allow you to take advantage of that better pressure without creating a problem with standard RV plumbing systems. Many higher end RV pumps that come on RVs have 65 to as much as 85 psi. New RVs often have their plumbing systems tested to 100 psi, or so, during the manufacturing process, but we recommend regulating incoming pressure to around 60-65 psi to provide a very nice operating system. "unquote"
As you can read it considers what is normal pressure for RV,s. I use the regulator that is a fixed adjustment that can be purchased at any RV store. I wonder why many of you want to buy the adjustible type that costs 4 to 5 times more? I am sure that you cannot adjust more water pressure if there is not enough and having the more simple regulator will protect the system from spikes.

Have not verified the information, but have been told by techs, etc that the RVIA standard is a minimum of 100PSI. Myself I have a Watts with a gauge from 'rvwaterfilterstore.com' set to 65PSI. Have not experienced any problems with leaks, etc. Have experienced go water flow for the shower.

I bought a Watts N45BU ...it is a 3/4" bore "whole-house" regulator. I bought the hose bib adaptors for each end and use quik-connects for easy installation. I got a separate gauge so I can check pressure before or after the regulator as desired.

I also have used a Shureflow 5.7gpm "Extreme series" water pump for the past years that supposedly puts out 65psi...

Why is a Watts household regulator better than something like this? It is also adjustable.

Just curious...

That unit would be fine if the internal passage diameter is as big as the one the Watts has. I think my Watts is 3/4 inch.
Rebuild kits are available for Watts regulators. Don't know about the Valtera.
I don't know how important that is though. My Watts is nine years old and still working fine.

Buy a cheap one and when you get the Watts regulator keep the cheap one for emergencies, like when a fellow camper forgets theirs.
Happy Trails.
Those 9.99 "regulators" are nothing but flow restrictors. Calibrated holes. They do not regulate pressure at all.

The Watts unit will flow 4-4.5 gallons per minute (Model 263A), which is about as good as it gets for these types of units and more than enough for an RV. The 263A, particularly with the stainless steel kit already installed, is all the water pressure regulator any RVer could ever need and with the stainless steel kit, corrosion proof. I can't find any information on the Valterra's flow rate, but, I would be surprised if it were as high as the Watt's. The Valterra website does show that their regulator should be set to 45-50 psi max, while the Watt's is recommended to be set at 60-65 psi for RV use...I've always kept mine at 60 psi and never had a problem with my plumbing at that pressure and I've had this Watts through three different trailers. As mentioned above, a rebuild kit (if it is ever needed) can be had for the Watts, the Valterra website does not indicate a rebuild kit as being available...they may have one available through their service department and just don't list it on their website though.

As for running "unregulated" at 60 psi...you should be fine. My brain is old and I no longer remember change dates, but, I believe older trailers were tested to 85 psi, while newer units are tested to 125 psi for integrity of the hardware and connectors. As mentioned above, I wouldn't rely on the 60 psi you have now (unregulated) as being a reliable constant. I stayed at a campground once that spiked to 128 psi, it can happen

Thanks for the info. Does anyone have any photos of how they have their Watts regulator set up for RV use?

In my case, I did it because I found the cheaper restrictors to limit the water flow too much for my liking.

HI,

60 lbs is too high for a rv as it should be around 45 maybe 50 but no higher. The Watts regulator is great and gives plenty of water volume while lowering the pressure.

If you don't want to build one yourself you can go to Camping World and they have a watts regulator with a meter so you can adjust the pressure to 45 lbs.

Be safe not sorry and lower your pressure for sure.

I don't have any photos handy but I mounted mine on my water softener with gauges to monitor pressure on the inlet and outlet.

Sorry to be the one, but I must say this statement is not true. I have always used the 40-50psi preset regulators from Camco.

Walmart.com: Camco Brass Water Regulator: Automotive

I have to replace them when they get clogged or start chattering.

I also have a water pressure gauge in line, and the gauge shows the pressure drops down to 40psi.

When I turn on a faucet, the pressure drops to 37psi for a split second, then right back to 40psi. , even while running the water.

I don't know how it works internally, but it does work.

I just installed a new one last night because 6mo old one was chattering, and I was worried about not using one because of the dreaded pressure 'spike' people have mentioned.
