RV water systems feature very small pipes can’t handle nearly as much pressure as usual home water pipes. Depending on your water hook-up’s proximity to a campground water main, you could receive low or high pressure. Unregulated incoming water pressure increases the chance for havoc to be wreaked upon your camper and a slew of necessary fixes thereafter. This regulator allows you to control the water pressure on its way in, as well as a visual gauge of current water pressure. Made with premium brass and a durable, liquid-filled gauge, it can handle any water source with ease. Plus, it’s designed with your safety in mind, being lead-free and containing a built-in inlet screen to filter out debris. We never hook up to a water connection without having this device first in-line.
