Compression Bathtub Faucet Valves

These valves are the least expensive and have been around for quite a long time. In this case, the bathtub faucet has both the hot and cold water handles. To close the water flow, you are required to turn off these handles.

You can only find ball valves in single handle faucets. The valve is designed to resemble a spherical disk which can either block or allow water to pass. With only a quarter turn in the anticlockwise direction, the valve allows the water to pass at the maximum rate. The model does not have washers and leaks are only possible as a result of corrosion. The model is long lasting hence does not require regular replacement.
