Water pressure regulator

You should not need to double up on regulators. You may be just finding latent failures in your plumbing do to looseness of fittings and such.
Hopefully you've found them all.

I have often used none with unknown water pressure without any leaks in my Pex.

At one time I used two of the standard RV pressure regulators together, since I had 2 of them, why not?

But then at one KOA park, the manager told us to make sure a regulator as their pressure was extremely high and could blow out our lines.

I really didn't know how effective my (by now older) regulators were, and we just got the new trailer. I decided to fill the fresh water tank and use the on-board pump, as the on-board pump would not spit out more pressure than what it was designed for, and no risk of blown pipes that way.

So, we've been doing it that ways ever since. Even with full hook-up sites, I fill the fresh water tank and pump from there. I'll leave the hose at the spigot as I have it on a real. And just stretch it over and fill the tank when it begins to get low. Been doing it this way for a few years now, and I have peace of mind the pressure is never too much for my trailer! AND, I don't have to buy another regulator.

This is something to consider? Noise of a water pump with the assurance you lines are "safe" or the quiet of garden hose with the uncertainty you lines may blow!

One may cancel the other. You need to fix the leaks. This is the only real solution my friend. Stop spending your money to compensate for poor quality.

If you are using one of those in-line restrictors, be aware that first they are not always very accurate and they have a high rate of failure.

No need to spend $75 for a good adjustable w/gauge as Amazon has one HERE for $49.95 And feee shipping with Prime.

I have been using Camco $10~$12 regulators for more than 25 years and never had one fail (have left a few at CG's by mistake). I do presently have a failed $75 Watt's regulator for my house.
The RV specific regs. marked "high flow" provide enough water for any type of use. I used to keep a gauge on it to monitor pressure but it was always spot on (40psi) so I quit using it.
There's no need to spend a fortune on a regulator.

Also, the PEX lines don't have any issues with much higher pressure but the faucets and toilets do. A reg. is a must for those if pressure is high.

How does it make any sense to save $75 while taking the chance of spending a thousand repairing leaks because you wouldn't spend the $75?

In all the years I've RV'd and the thousands of posts I've read on this forum, I have never read of damage to a RV's water system because of a Camco (or any other brand) regulator failed. I have seen the expensive, whole house regs fail and information about those failures is just a Google away. (and like I wrote, I have one that's bad)
So it makes no sense to me to waste the extra money.

One advantage you would generally get with the more expensive regulators is that they do not restrict water flow as much as the cheap regulators.

I'm sure Amazon has reviews on the regulators and that the Camco brand is good and has been around for many years. But on the other hand... I have friends that don't trust the quality unless they have spent enormous amounts of money on their purchases.
Oh well, Brian
