6.5.6 Water Damage
Criterion
text:
Collectors
and support shall be installed in such a manner that water flowing
off the collector surface will not damage the building or cause
premature erosion of the roof. Water tanks located in or above
the living space shall be installed on a drip pan with a drain
line to a waste line or outside or have other means to safely
remove any excess liquid.
Comments:
This criterion requires that water heaters must include drip pans
when installed in or above living spaces. Drip pans must incorporate
a drain line to remove excess fluid.
Installers
should also understand and follow local code requirements related
to this issue.
The
example in Figure 1 below shows a water heater installed in a
kitchen area. Because of this, the tank must incorporate a drip
pan, which in this case it does not. (The installer did route
the pressure and temperature relief valve outlet out of the kitchen.)
Figure 1
Figure
2 indicates an acceptable water heater drip pan. Note the fitting
allowing the incorporation of a drain line plumbed to the outside,
if need be.
