Boltigen Handle Adjustable RV Water Pressure Regulator Valve, Brass Lead-Free Reducer with Gauge 160PSI and 4 Inlet Screened Filters,for RV Camper, Travel Trailer, or Garden (Gold-Handle Adjustable)

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.

easy ti install easy to operate

Good product came with everything you need including Teflon tape and extra screens/washers.

Highly recommend for RV use, I lowered the pressure to 25 PSA to protect hoses/fittings in a 5-year old RV.

It reads accurately…adjustable.
