Water pressure regulator

Hi guys,

I have an 83 Tioga by fleetwood on a Ford E350 chassis. Being that the rig is pretty old I was wondering if I should buy an adjustable water pressure regulator? I've already done some repairs on small leaks I've found. When plugged into shore water, Is it a good idea to run less pressure on an older system to reduce the risks of leaks. Also, around what PSI is my on board 12volt pump running at? The pressure regulators that are not adjustable obviously come preset to a certain PSI so I'm just wondering if I can pick up one of those or if I should get an adjustable. Thank you for your help!

This is what I use, got everything from Lowe's, gauge can be used to check campground pressure and for setting pressure at the regulator. I keep mine set at 60PSI. Would never hurt to set it lower if you can put up with the lower pressure

Your onboard water pump maintains system pressure at about 45 psi, so your plumbing has to be able to handle at least that much. If you get an external regulator, you could set it the same. The non-adjustable RV regualtors are typically factory set for around 40 psi, but they also restrict the volume of flow a lot, so one of the larger ones suggested by others would be better. I run mine at about 60 psi.

FWIW I'd run 45 if I was running park water. I don't run park water. The first unit we had was an older high milage unit to see if we liked the camping style. One night the toilet developed a slow leak on city water. No extra noise but quite a mess. Now even with the new one we run off the internal pump. No surprises over over filled tanks and the pump makes enough noise to catch my attention if there is a problem. ;-)

Old or new.. Get one of the following

A pressure gauge, if you can not find an "Inline" model then add a "Y" connector This goes on the OUTLET side of the next item:
Pressure Gauge w/Garden Hose Adaptor -

I actually do not like WATTS gauges all that much.

Watts, 1/2 or 3/4 inch adjustable regulator with hose adapters or a
Zurin 1/2 or 3/4 inch adjustable regulator with hose adapters.
WATTS Pressure Regulator, 3/4 In, 10 to 25 psi - G5308773 at Zoro

NOTE: links in this post are EXAMPLE only so you know what to look for..I shop local plumbing supply, Lowes, HomeDepot,Mennards for these products.. Though you may find the odd CW that has a bag with all the needed stuff in it.

OR; (Skip the pressure gauge if you get this one: Valterra A01-1117VP Brass Lead-Free Adjustable Water Regulator: Automotive

Amazon listing,if viewing long time from now may have expiered

I have used Watts and Zurin, when new they are fantastic, When aged you start to loose pressure, but rebuild kits exist.
Home is where I park it!
