Water heater life depends upon water quality, water pressure and
the environment in which the water heater is installed. Water heaters
are sometimes installed in locations where leakage may result in
property damage, even with the use of a drain pan piped to a drain.
However, unanticipated damage can be reduced or prevented by
a leak detector or water shut-off device used in conjunction with a
piped drain pan. These devices are available from some plumbing
supply wholesalers and retailers, and detect and react to leakage
in various ways:
•
Sensors mounted in the drain pan that trigger an alarm or turn
off the incoming water to the water heater when leakage is
detected.
•
Sensors mounted in the drain pan that turn off the water
supply to the entire home when water is detected in the drain
pan.
•
Water supply shut-off devices that activate based on the water
pressure differential between the cold water and how water
pipes connected to the water heater.
•
Devices that will turn off the gas supply to a gas water heater
while at the same time shutting off its water supply.
CLEARANCES
A minimum clearance of 4" must be allowed for access to replaceable
parts such as thermostats, drain valve and relief valve.
Adequate clearance for servicing this water heater should be
considered before installation, such as changing the anodes, etc.
Electrical Shock Hazard
If the water heater becomes immersed
in water up to or above the level of the
bottom of the element doors, the
heater should be examined by a
qualified service agency before it is
placed in operation.
