Heat Trap Nipples
Heat trap nipples are specialized fittings installed on the hot and cold connections of a water heater to reduce standby heat loss. Inside, a ball or flap lets water flow but blocks natural thermosiphoning that would pull heat out of the tank. They improve efficiency and can lower operating costs.
