Camco RV Adjustable Brass Water Pressure Regulator (40058)

Works as advertised. I haven't attempted to take it off of the factory setting of about 45 psi. Be careful storing it or you're going to damage the meter. I keep a short length of hose that allows the device and my filter to lay on the ground. Then I just hook my primary hose to the filter and to my rig.

This Camco adjustable brass water pressure regulator is one of those small RV essentials that makes a big difference. It threads on easily, feels solid, and the brass construction gives it a heavy-duty, long-lasting feel compared to cheaper plastic versions. I like that it's adjustable—being able to fine-tune the PSI means I can protect my RV plumbing without sacrificing water flow at the sink or shower. The gauge is clear and easy to read, and the regulator doesn't leak or hiss under pressure. After a few camping trips, it's still holding strong and working perfectly. Definitely worth keeping in every RV toolkit.

the previous one only lasted 8 yrs before having a drip leak. actually that's really good service, I'm happy with it.

I wanted a water pressure regulator with a gauge so I could adjust my sprinkler system water pressure more accurately and you had such a product at a reasonable price.

Works great now my garden hoses won't explode

Works as advertised and easy to use.

Will crack in a freeze. must keep it insulated in the winter ❄️

It should be easier to adjust the pressure. You shouldn't need a screwdriver.

Very hard to get a true reading when used on my hose fitting. I was trying to get it adjusted down to 10psi to use a plumbing bladder, and it took forever to get it adjusted to around 15psi. I don't think the regulator likes to go that low.

My first one was good. It bounced around for 2 years of ft travel, but the glass broke. This one has water leaking inside the gauge dial within the first week, which makes it inaccurate. I saw the same thing on the RV park next to me. I guess they don't make them like they used to.
