• If stop valves are used, make sure that they are fully open.
• Make sure that the hot and cold inlet pipes are connected properly, and that there are no cross-connections or
leaking stop valves.
• Check the hot water heater output to make sure that it is at least 10° F above the set temperature.
Be sure to close the appropriate shut-off valves prior to disassembly of the valve and reopen the valves after inspection and
