Review on Camco Brass Water Pressure Regulator with Gauge - Safeguard RV Plumbing & Hoses from High-Pressure City Water - Easy-to-Read Gauge, Lead Free (40064) by Richard Carroll

When the water pressure dropped on our bus we didn't know if it was a low pressure source, a bad regulator, a clogged hose or something else lay water filter needed. We decided to replace the regulator to find and fix the problem. We found it with a pressure gauge offered on the same Revain page as the basic regulator. For a few bucks more it seemed like the way to go. Source pressure is not unknown. We think it was a good choice. Both the pressure gauge and the regulator worked perfectly. (It turned out that the filter needed to be replaced. We weren't expecting such an easy solution. It was too soon to change the filter, but the water must have been too thick when it came in from the previous park that we were.)
