A temperature sensitive safety valve assembly includes a housing for mounting at a faucet outlet and a safety valve element consisting of a rigid cap and an elastic bellows containing a body of temperature sensitive material. Below a predetermined temperature, the bellows has a first condition permitting flow of water towards the faucet outlet. Above the predetermined temperature, the bellows has a second condition restricting flow of water. The bellows also has a third condition, actuated by loss of at least a portion of the body of temperature sensitive material, in which a seal surface of the cap engages with an opposed seat surface of the housing to restrict flow of water towards the faucet outlet.
