Pressure Reducing Regulator Setting

[TheOneRLP]

I’ve purchase an adjustable Pressure Reducing Regulato for my 2012 Cruiser Fun Finder X-189FBS camp trailer.

I was told I needed one when using the City Water line so as to not be bursting my pipe fittings with too high of City Water pressure coming into my system.

Can someone please tell me what a safe pressure adjustment would be to set the regulator at to not have a bursting fitting problem?

Thanks very much in advance!!!

Another thing or 3
First In-line reaqulators come if a few different "Flavors"
The Cylinderical ones abourt 3/4 inch some have "Wings" some have a bright plastic grip on the female end.. The proper setting for those is "on the store shelf"

Some have a bell shaped upper housing... See thread above for proper settings.

Now the reason for this.. Due to hyper chlornation by the city at one RV park I took to filling the on-board tank. The excess bleach quickly was lost and the water became fit to drink.... No need for pressure regulator as once tank was full the spigot was OFF.. Worked double well when things got COLD out. My rig had heated tanks.

This is what we do.

Many years ago on our boat (fresh water system is essentially the same), we woke up in the night to a hissing noise. Almost rolled over and went back to sleep. Went looking and one of the fittings had cracked and was spewing water in the bilge. In an RV, it could result in thoroughly soaked plywood floors.

We have to dump the tanks every few days when on full hookup anyway, so no major effort to fill the fresh water while draining the waste tanks.

Just checked. They come set at 65 psi.

Airstreams come with built in regulators at the freshwater inlet. I believe they are set for 60lbs. As others have stated, pex is rated for much higher. I think 60 is plenty...

We have ours set at 45

[wa8yxm]

I set mine to 50 (Rig labeled 40 or 45) never had a problem.
I'm told some valves may start leaking over 60... Never saw it but that's what I'm told.

Aside from the setting, I make it habit to turn the water supply off when leaving the RV for any period of time. Small thing to do and mitigates the risk of coming back to a flooded RV if anything does break. This goes for the water pump also if not on city water.

55 PSI

[Bobbo]

Twenty years ago the recommendation by ShurFlo was 45 psi. Today, it is 55 psi.

[ssthrd]

Pex is good for 160PSI, and the crimp joints are as good as the person who installed them. I have used 60PSI on my rv's for the last 15 years with no problems. 80 PSI in my homes.

The last campground we were in, the line pressure was 120PSI............ Good idea to have and use a pressure reducing valve for sure.

I believe that the generic "owner's manual" for the rv's that I have owned mentions 60PSI as a max.

[bob213]

I run my watts regulator at 55 psi. Pex will handle much more but the cheap faucets have lower limits. More than 55 though.

[opnspaces]

45 psi
I believe the off the shelf fixed setting regulators are set to 45 PSI so I would start there.
