PEX psi rating is dependent on temperature

100# @180*F
160# @74*F

so your RV plumbing can easily handle 50 psi.
BUT pressure isn't the only thing to consider......volume (flow rate) is what really matters.
The common in-line 'regulators' have a very low flow rate.
Use a good quality adjustable regulator with a flow rate of 3.5-4 gpm and set it for 50# static pressure (no flow). Watts Brand are top notch.

Also remove and flow restrictors in shower hose, handle and/or head.


Is it time for your medication or mine?

What I meant to say was PEX is rated for between 40-60 PSI in TRAILERS. I know it's rated much higher for other applications. I just didn't want a newbie to get any wild ideas and crank it up to 80 PSI or whatever.

I'd like to see where you get that.


Yep, actually drove to all of these places---in the last eight years. Missed Rhode Island and New Jersey.

If you're talking about a pressure regulator, they should be hooked up at the other end, where the on/off valve is.

While I understand connecting it at the source would also protect the hose, it would appear to me the trailer would see no difference. Is there a reason I'm not seeing why it "should" be connected there?

Thanks,

About those Watts regulators,they are great and well worth the price...but....Don't leave it behind when you move. (No need for me to admit to anything here.)If you need to buy a second one,it makes the total cost really high. 'Nuff said?


That's why I connect the regulator directly to the water inlet on my fiver. It stays connected there all the time. I have heard that I will blow out my hose by doing this but I can tell you that in all the years I've been doing this it has NEVER happened.

I'm just thinking of wear and tear of the water inlet screw on the RV. Probably not a huge issue.

Our shower head had this plastic disk washer looking thing with a little hole in it.

I removed this little plastic disc between the shower head and hose. This made a world of difference.
Also, you can't beat an Oxegenic shower head and a Watts water regulator.

Have not used or needed a pressure regulator since we starting RVing in 2008. But only in AL, GA, FL, MS, LA, and TX.

We were at Fishing Bridge RV campground in Yellowstone a couple of weeks back. The pressure would exceed 100 psi at times. Glad I had a water pressure regulator.

I have stayed at many parks with pressure greater than 75 psi. I have a gauge installed on the incoming line of my regulator.
