If your water heater is in a garage
or a non-finished basement where leaking water would flow harmlessly into
a drain, a drain pan is not necessary. However, if the heater is in or
above a living space where leaking could cause extensive water damage,
it is highly recommended to use a drain pan to prevent or minimize property
damage. Pans should be plumbed to a proper drain or to a safe disposal
area. Drain pans are available in various diameters to accommodate all
size water heaters. Pans should be 4" wider in diameter than the diameter
of the water heater. Plastic pans should be used with electric water heaters,
and metal pans should be used for gas water heaters and can be used with
electric water heaters. Codes in some areas require metal pans for all
heaters installed in a living space. |
