Abstract
A faucet includes a faucet body provided with a receiving chamber, a first outlet port and a second outlet port, a first check valve mounted in the receiving chamber of the faucet body and located between the first outlet port and the second outlet port of the faucet body, a water output unit mounted on the faucet body and having an inner portion provided with a receiving space connected to the second outlet port of the faucet body, and a second check valve mounted in the receiving space of the water output unit. Thus, the first check valve co-operates with the second check valve to form a double anti-reverse function to prevent the waste water from flowing backward into the water entrance of the faucet body so as to protect the water source of the faucet.
