Abstract
A water input connection for a faucet includes a body which has a water inlet and a water outlet. There is a chamber within the body and there is a seat adjacent the water inlet. An antisiphon check valve is movable within the body chamber toward and away from the seat to open and close the water inlet connection. There is an antiflow valve movable within the body to open and close the water outlet connection. A spring is positioned within the body and biases both the antiflow valve and the antisiphon valve toward water inlet and water outlet closing positions.
