Water pressure problem
Need help diagnosing a water pressure problem. In March I installed a dual canister system linked to a water pressure regulator (see photos). Starting about a week ago I found water on the floor of the basement storage area. I traced it to the connection at the valve that sends the water to either the coach or the fresh water tank. I made that repair.
Then I found water again. I noticed the water regulator gauge was showing 100 psi. Using a test gauge I checked the city water connection. It showed 75 psi. I have the regulator set to 57 psi. To check the regulator I put an old Camco restricter (50-55 psi) at the city connection. After about 4 hours the regulator was again showing about 85 psi. I found water leaking from the impeller of the water pump.
At this point I'm lost as to what to do next. I don't understand how a restricter would allow the increased pressure. I've ordered a new regulator. Should I also replace the water pump? I'm looking for ideas to try before spending more $$$. Thanks

I like your setup. Very clean.
When you get the new regulator, put it on the spicket first then attach the hose leading to your rig.
I would guess a failed regulator.
I fill our freshwater tank and use the water from there.
When we leave, we turn off everything. Precludes leaks.

I have our Watts regulator installed at the hose bib, otherwise, in hot weather and high water pressure the hose will fail due to the high pressure. We had one of the lower quality RV adjustable regulators and it only lasted about two years. Got a Watts Series LFN45B-M1 regulator, and it hasn't failed for years.

I do the same as Bob and have the regulator set at 45.

Like rohrmann, a Watts regulator is the way to go. You won't find them in CW nor any other regulator worth anything. Ours regulates pressure without having an affect on volume of flow. We maintain about 60 psi limit.

Water pump recommendation
Looking for suggestions for a replacement water pump. The original was replaced with a Flow Master after the TX freeze back in Feb. The Flow Master is leaking from the impeller.

JDarwin - did you get that Watts regulator at Home Depot?
Rohrman - where did you find that snazzy stainless steel braided section of hose??

The stainless steel braided hose is a water heater flex hose with added fittings so it can connect to a hose bib. https://www.amazon.com/Fluidmaster-B...4&sr=8-37&th=1

Yep, got today and put it together. Now I’m looking to replace the water pump. I did a little investigating and am looking at a Sea Flo 42.

We got a Remco, a big one. One thing to consider is getting a variable speed pump. It reduces the need for an accumulator. Also, strong pumps require more power and in some cases the power supply wiring needs to be upsized. But, it's nice to shower with city like water pressure since it has pressure and volume of flow.

I replaced ours with this one:
https://www.amazon.com/Shurflo-2088-...9413271&sr=8-3
It's the same one we had in our Class C. In four years we have never connected to a campground water supply because the thought of it scares me to death (I've seen at least 4 RV's with water pouring out of them for one reason or another). The sound of the pump is an immediate telltale that water is running somewhere. When we leave we always turn the pump off.
The pump has always worked well.

It's for this very reason I never stay connected to my garden hose. I always fill my fresh water tank and then disconnect the garden hoses, and pump with my on-board pump from the tank. I was warned a long time ago about water pressure being too high and how fickle plumbing is inside campers. I for one did not want repairs, so always, thereafter, use my on-board water pump. This way, I never need a pressure regulator. I've also never had a water line leak.
Long time ago, I had a garden hose connected to the campground faucet and turned on. The sunny temperature that day got near 100, and asphalt was probably closer to 150 or more. The garden hose started expanding, like a gigantic balloon when I saw it, and before I could get the water turned off at the spigot, it exploded. That was an impressive sight, but I sure don't want to experience that ever again!
Nope, after I was told about cheap and/or failing water pressure regulators, and how vulnerable RV water plumbing is to over-pressure.... I said ... NEVER! And it's been Never Again!

I bought a Seaflo series 42 off Amazon. It’ll be here tomorrow. It’s selling points to me were a 700 hour motor, runs continuously at low flow levels, 4 diaphragm chambers and emptying the tank won’t harm the unit. It looks identical to the Shurflo 4008.

What about noise? We still have the stock pump that came from the factory and everyone in the campground knows when it comes on.
I've added some foam to a few of the hoses near the pump that were rubbing, but it hasn't really affected the noise.

The reviews say it is more quiet than the OEM pump. I like the feature of variable flow without the pump cycling.
