Camper water pressure
I have a 2017 Keystone Hideout 26RLS and I started using an adjustable water pressure regulator at the city water connection. I have paged through the owners manual, but cannot find what the acceptable pressure recommendations are. I have set it at 30psi, but the toilet does not appear to flush properly and the shower flow is weak. I have heard that newly built campers can be operated at near 60psi. Any recommendations? I hesitate to try pressure above 30psi until I hear different

I was having low shower pressure as well and ditched my cheap non-adjustable unit for a cheap adjustable one with a gauge. It was set for 55 PSI and the pressure at the shower and sink seems better now.

Set it at 45 or 50 and see if that doesn't give you better flow.

45psi seems to be the sweet spot for us.

I think the on-board pump is rated for 55ish PSI?
I have mine set for 55 - 60.

I never dial in over 50#. If that's not enough, you probably have other issues.
Most campers have water restrictors in their plumbing, (faucets / shower heads), so that if you are dry camping, you save water to the point of having a mere drizzle at the tap. but what the HEY, 30 gal. FW lasted all week!
If you CG GLAMP, remove the onboard restrictors, and go for it, using only the hose restrictor! My stick and mortar house is only set for 45#, and it peels skin in the shower if you're not careful, and we're talking sweated copper, not cheap PEC fittings hidden in cheap walls!
Good Luck,

Here is what I use, remember not all adjustable regulators are created equal... It's all about GPM... 4-5 GPM is ideal... many of the other regulators will not flow that rate because of restrictions..

What I am wondering is if I reduced mine when I installed the winterization kit. I had to add 2, 90 degree fittings to keep the main water line from kinking in the pump box.

Pressure would be constant regardless of the elbows.

GPM would not however... always keep the run as straight and as short as possible.. I do doubt that two 90 degree 3/4" elbows reduced anything significantly...

Don't think they have restrictors built in, maybe aereators at each faucet that tend to reduce pressure. There's a back flow preventer at the hose connection on the rv & possibly at the faucet that will reduce flow.
Even with the adjustable regulator, unless it's higher than the preset on the regulator, you'll only get whatever's at the faucet. If you use your onboard pump you only get whatever it's rated at, usually between 40-55 psi depending on the pump. Don't know of any way to increase the pressure without adding a pump to the faucet.
I will say 30 psi is WAY TOO low!
My regulator is set at 55 psi & if the park has at least that it's a good pressure, but most have either very low or very high.

Ours is set at 50 psi and we have not had any water pressure issues. I have no idea how much psi the trailer plumbing can handle.

Howdy All;
Here's the PEX spec. sheet for those that like solid numbers to work from.
Temp. ,flow, pressure, it's all there.

Those fittings are not rated as high as the PEX tubing and the joints/fittings/PEX tubing all get "vibrated down the highway" (think subjected to an earthquake with every mile). So the "strength/reliability" of an RV plumbing system is significantly lower than the PEX specifications.
To answer the OP's first post, I set my adjustable pressure regulator at 45PSI and I've never had any problems with volume or with pressure inside our RV. We do have an aftermarket shower head which makes a significant difference. Our outdoor shower has the OEM shower head and it literally "trickles water" where the indoor shower head provides a satisfactory result, even for washing shampoo out of a "full head of hair"
YMMV

I check the post pressure with a test gauge, if it's less than 60, I don't use the reducer piece. But for showers, I use my on board pump and fresh water tank. I even replaced my onboard pump with the remco aquajet. Significant pressure and flow difference!

Thanks everyone for the advise. We have one more outing left this year at the end of the month so I will give the pressure increase a try. I wasn't sure on how much pressure the lines and fitting in the camper would handle.
