The assembly consists of a bronze body with threaded ends, stainless steel ball, bronze disc, and cadmium plated steel loading spring with bronze spring housing.  An adjustment screw protection cap is provided.  The valve is suitable for pressures up to 300 psig at  300° F maximum.

Most of the time, high water pressure isn’t the homeowner’s fault. For example, living close to a fire hydrant can result in higher water pressure. Usually, however, it has to do with your municipal water supply. It has to supply water to a vast area and therefore it pumps water throughout the city at higher pressures than what you want coming into your home. It’s recommended to keep your home’s water pressure between 40 and 60 PSI (pounds per square inch). It should never exceed 60 PSI, or significant damage can occur to your pipes, faucets, and appliances.

We recommend having your new pressure-reducing valve installed by a trained professional, such as one of our master plumbers. Bieg Plumbing has served the St. Louis area for 60 years. Over that time, we’ve seen it all, so don’t hesitate to contact us to schedule an inspection. We’ll find the problem and fix it promptly.

To check your water pressure, you’ll need to attach a pressure gauge to the faucet closest to your water meter. When it’s obvious you have a pressure problem, the fix is usually to install a simple pressure-reducing valve, usually installed near your shut-off valve. This limits your water pressure to a certain range and takes the load off of your plumbing system. If your home was built after 2002, a PRV may already be installed, since that was the year it became required on all new homes. However, a typical PRV’s lifespan is about 7 to 12 years.

The Model R Relief Valve should be used as a safety device to relieve excess pressure and not as a regulating valve to maintain a constant upstream pressure. It is designed to relieve excess pressure in lines containing any grade of fuel oil. It is also suitable for use with water and air. It opens to relieve at the “set” pressure (adjustable) and closes tightly when the pressure drops.
