The Caleffi PLUMBVENT is a space-saving, low-lead automatic air vent. It is designed and manufactured specifically to vent air from water at high points in plumbing and domestic hot water system piping. 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. It complies with NSF/ANSI 372, Drinking Water System Components – Lead Content Reduction of Lead in Drinking Water Act, California Health and Safety Code 116875 S.3874 (AB1953), and Vermont S152.
