PLUMBVENT, a space-saving, low lead automatic air vent designed and manufactured specifically to vent air from water at high points in plumbing and domestic hot water system piping, is now available from Caleffi. Common applications include air elimination on domestic hot water storage tanks, at the top of plumbing risers and near the inlet of a hot water recirculation pump to reduce the potential for air lock. Available in 1⁄2” NPT male connection, the vent is supplied with a safety hygroscopic cap to protect against potential vent leakage.
