Abstract
A water delivery system is provided, comprising at least one sink with a faucet device comprising a cold water faucet part and a hot water faucet part, a cold water line to the at least one sink, a hot water line to the at least one sink, and a valve associated with the at least one sink allowing in an open state the transport of water between the hot water line and the cold water line and inhibiting in a closed state the transport of water between the hot water line and the cold water line, wherein the open state and the closed state of the valve depend solely on whether a differential pressure across the valve is below or above a threshold value.

Water delivery system, comprising:
- at least one sink with a faucet device comprising a cold water faucet part and a hot water faucet part;
- a cold water line to the at least one sink;
- a hot water line to the at least one sink;
- and
- a valve associated with the at least one sink allowing in an open state the transport of water between the hot water line and the cold water line and inhibiting in a closed state the transport of water between the hot water line and the cold water line;
- wherein the open state and the closed state of the valve depend solely on whether a differential pressure across the valve is below or above a threshold value.
Valve for a sink, said valve comprising:
- a hot water inlet;
- a cold water inlet;
- wherein the hot water inlet and the cold water inlet are operatively connected;
- and
- a closing device for closing the connection between the hot water inlet and the cold water inlet if a differential pressure reaches a threshold value.
