No lead brass relief valve for cold water installations only. Available in ½” and ¾” Male Threaded Connections. Pre-set at either 75 or 100 psi. Protects pipes and pressure tanks from damage due to excessive pressure. (These valves are NOT the temperature/pressure relief valves that are required with water heaters.) Relief valves must be installed so that they drain into a floor drain, sump, or other safe location with an air break. The outlet pipe must have a diameter at least as large as the relief valve outlet.
