Hot and cold connection solutions are available with options for unique installation needs, including isolation valves, vacuum relief valves, and expansion tank service valves. All kits feature FIP dielectric unions for connection to the water heater and press or sweat options for connection to system piping. All products are forged from lead-free dezincification-resistant brass.
