Keep Water Under Control With Pressure Relief Valves & Regulators


Limit the flow of water with a pressure-reducing valve. This device works by limiting how much pressure is inside the valve, causing friction and reducing the speed of the water that travels through. With a pressure relief valve, you can modify your network of pipes so that water doesn't come out of fittings like garden hoses in full force. This valve can also help protect plumbing connections and reduce utility costs.


The inlet size of a pressure relief valve matches the pipe that it's connected for, so they come in a range of sizes. For example, if you want to regulate water from a water heater that has 1-inch pipes, a 1-inch valve makes for a suitable water heater pressure relief valve.


Another crucial part to look for is a water hammer arrestor. This device works to protect pipes by absorbing shock when water in a system suddenly stops flowing. An arrestor works best when installed between the water supply line and the shutoff valve.
