the tubing/piping before connecting to the tailpiece.
NOTE:
If soldering, remove unions and gaskets from valve body prior to
soldering to prevent damage to valve from excessive heat.
6. Flush piping again, install valve using filter gasket on
hot and cold water inlets and fiber gasket on mixed
water outlet.
7. Turn on the cold and hot water. If any leaks are observed,
tighten connections as necessary to stop leak
