Pressure regulator at source vs. destination

Consistent pressure/flow regardless of where you go
Easy to flip switch off when going to bed, leaving RV.
Pump short cycles......find the leak!


I do use reg (Watts adjustable) on hose to fill fresh water tank

You'll need a VERT GOOD hose if you permanently mount your pressure regulator. Year ago, there used to be a vendor known as the "Water Filter Man" at many of the big RV shows. He sold great hoses for $1 a foot plus $6 for solid brass ends. I bought a couple from him and then bought some of the hose and made some more. They still look like new some 10 years later. Unfortunately, I haven't seen the Water Filter Man is years but here's a link to the bulk hose he cut his from:

K6155-08X300 Kuriyama Kuri Tec K6155 Series High Purity Non-Toxic PVC Potable White Water Hose - 1/2" ID - .750" OD - 300ft

300ft may be more than you can use but if you make a few in several different lengths to meet your needs (10', 15', 25' and 50' - you've gone through 100' already), you probably wouldn't have any problem making up a few extra and selling them to your friends when they see how nice they are. I don't have a source on the solid brass fittings that he crimped on.

I put my regulator on the spigot even though I always use these hoses. The sad thing is, I buy whole house 3/4" regulators and adapter them to male/female hose fittings. The whole thing runs around $50 and occasionally I leave them behind for the next camper - I really hate when I do that!

I can only tell you how I do it. I have a 6' hose from the spigot to a whole house water filter. Then I put the Watts regulator, then the hose to the RV.

I also prefer water in the tank ad use the pump. No pressure problems.

I just remembered a story a guy told me. He said he was warned that he needed a pressure regulator when he checked in. He parked and hooked up. He attached his regulator behind the filter. Later in the afternoon he heard small explosion. Went outside to find the top blown off his filter.

I recently purchased a semi-expensive adjustable water pressure regulator with gauge. I would rather have it at the RV end of the water hose than the spigot end. I'm not sure if it even makes a difference. My rig has an enclosed compartment for all the water and sewer hookups so it would be ideal to be able to keep it there.

Is this just a stupid question or does it make a difference which end of the hose I place the regulator?

One of the places I park (actually 2 0f them) have measured pressure at 120 PSI or more (Saw the gauge myself at the one I only visited once).. That kind of pressure can blow your hose up.. Just like in the cartoons.

So put it first.

I put the regulator after the filter. Sediment can destroy that new regulator. My setup goes like this;

faucet
wye
hose
sediment filter
regulator
hose
RV

The other side of the wye gets an expandable hose (Think Pocket Hose but better). In case of fire the wye is opened and within seconds the expandable hose is ready to use. Some campgrounds actually require there to always be a hose ready for fires. I hook one up as standard practice required or not.

I also use brass quick connect fittings everywhere except the faucet.

If that pressure is after the Watts regulator then it has failed. I had to replace mine because it had failed so I am surprised you haven't blown out a toilet fill valve or something.

No, it’s after the gauge, which is “street pressure”

After unhooking the hose from the faucet and discovering that night the pressure regulator was still on the faucet back at the campground, I now put the pressure regulator on the RV end. I have yet to see a hose burst, and a couple cheap hoses are still less than a good adjustable pressure regulator.

That’s my experience. You find a lot of regulators in campgrounds.

I place the regulator at the park bib. Hoses may weaken and fail over time if you place it on the RV end. Either way the RV is protected. I left mine once on the park pipe and now am careful what I am taking off. Just another mental check list item.
