It works by giving you more control over the water flow and pressure into your recreational vehicle. The piece of equipment is easy to use and adjust. In fact, you can just use a screwdriver in adjusting the water flow and pressure.

The RV water pressure regulator will activate when the water starts traveling through the end of regulator’s inlet end and just around the flow area’s fixed seat. The water will then enter a cylinder attached to a larger diaphragm close to the end of the outlet.

The pressure will then act on the diaphragm located inside the water pressure regulator, trying to close the area for the flow. The area will just close enough in order to keep the set flow and pressure.

One is the in line barrel type that we’ve discussed earlier. It is not expensive and is made to control between 40-45PSI. The other one is the high flow in line barrel type we’ve talked about earlier. It is chosen for its high rsa rate, but it doesn’t let you adjust water pressure, too.
