Abstract
A showerhead system with a normally open, temperature controlled first water valve coupled between a hot water source supply inlet and a purge outlet. The first water valve is configured to move from its normally open position to a closed position to restrict water passing from the hot water source supply inlet to the purge outlet when the temperature controlled water valve reaches a predetermined temperature. In a first mode, the first water valve purges water from the hot water source supply inlet through the purge outlet until the thermal actuator reaches the predetermined temperature. In a second mode, the first water valve blocks water entering the first water valve from passing through the purge outlet toward the showerhead outlet. In an optional third mode, a normally closed, manual second water valve is open and passes water through the showerhead outlet.
