Works great for my application
Although it is described as an RV pressure regulator, I repurposed it to provide low-pressure water to a hidden 2-gallon reservoir that is kept full by a small float value. (The reservoir is in the large turquoise pot on the extreme right in the photo showing the birdbath.) Water from that reservoir then provides very low-pressure water to a small birdbath at an adjustable rate, via a small valve, from a drip every few seconds to several per second as needed to keep it full during our summers. I have tried numerous ways that seemed to work at first, but the high heat of our summers and the high supply pressure resulted in various failures (geysers, floods, or a dry birdbath). The ability to dial down the pressure to under 15 PSI and provide that *constantly* makes this a much better option than the spring-based pressure regulators that should only be used once or twice a day (e.g., on a timer to provide water to a drip irrigation system). So far, everything is working and the doves, finches, quail, and others are loving it.

Quality product
Ordered this pressure regulator because we have very high water pressure. The 25 psi pressure reducing valves would not work. This product does the work required.

Works good see review.
This is my 2nd one, I love the pressure regulator it helps when setting up to see what kind of water pressure there is. It's very easy to adjust with no tools. I only gave it a 4 because the 1st one I bought only latest one camping season (about 50 nights) the oil leaked out of the gage area, it would still read the pressure just wasn't sure what it was. 2nd one I have had since June and seems to be working ok.

Excellent product and easy to adjust
This was an excellent upgrade to the fixed pressure regulator I was using for years in my RV. Water pressure at campgrounds varies considerably and getting it right to have a decent shower...and not blow up your water lines..can sometimes be challenging. This device is made very well and the nice feature is how easy it is to adjust. I find setting it up closer to 60 psi is far better than the 40 psi the fixed regulators stick you with. Plus my RV specs allow up to 80 psi....but that high is not necessary. Well made, no leaks, easy to adjust.

Quality is poor. Broke with about 30 days of light use.
Used this about 4 times last summer (2024) and it worked OK. Adjusting it to a specific level ( I like it around 40-45 PSI) and making it stick was a real challenge. I'd hook it up adjust to 45 or so, and come back later and its at 55. Then I re-adjust down, and then the water flow is very low and I'd check it later an it's at 20. So, this unit was hard to dial in. Now, this year I pulled the rig out of storage (BTW,the regulator was stored in the house, so it was not subject to cold temps), and we are on a Memorial day trip, and the oil that was in the gauge leaked out and the pressure needle has somehow found its way over to the wrong side of the rest pin just below the Zero mark (photos included) - I'm speculating that the spring inside broke. So now this gauge is useless. So, we got about 30 days total of use from it. It looks brand new, but is nothing more than a faucet attachment. This is the second one that did this. Move on and buy something else.
