8. Check Operation of Valves
WARNING: Risk of personal injury. Wrap a towel around the
pipe plug to prevent water spray. Water will purge from the
supply tube when you remove the plug.
Thread a 3/8" pipe plug into the top of the spout supply tube.
Ensure that the valves are closed (cold = fully counterclockwise;
hot = fully clockwise).
Turn on the main water supply and check the complete
installation for leaks with the valves closed and open.
Repair leaks as needed.
Close both valves and turn off the main water supply.
Carefully loosen the pipe plug to remove pressure.
Thread the pipe plug back into the spout supply tube.
Install cardboard plaster guards over both valves and the spout
supply tube.
