– provide minimal friction loss
• Locate water heater so that any leakage from
the tank or water connections will not cause
damage to the area adjoining the water heater
or to lower floors in the structure.
– When such a location is unavoidable, a
suitable drain pan with adequate drainage,
should be placed under the water heater.
