water heater pan

[Ken Meyer]

Commercial inspection, small office building. The hot water heater is in the attic space directly over the kitchen area. I was told that they had problems with the water heater leaking, so they put a pan under it. Good idea, especially since the WH is 20+ years old. They ran 3/4" PVC down from the pan to the kitchen sink. It comes down the interior wall and with two 90 degree els, hangs over the edge of the sink. Is this wrong, or just ugly?

Shoulda taken a picture, but didn't.

Residential requirements. 2006 IRC states that a separate 3/4 wast line be run and terminate over a suitably located indirect

waste receptor or shall extend to the exterior of the

building and terminate not less than 6 inches and

not more than 24 inches above the adjacent

ground surface.

P2801.5 Required pan. Wherewater heaters or hotwater storage

tanks are installed in locations where leakage of the tanks

or connections will cause damage, the tank orwater heater shall

be installed in a galvanized steel pan having a minimum thickness

of 24 gage (0.016 inch) (0.4 mm) or other pans for such

use. Listed pans shall comply with CSA LC3.

P2801.5.1 Pan size and drain. The pan shall be not less

than 11/2 inches (38 mm) deep and shall be of sufficient size

and shape to receive all dripping or condensate from the

I think it's just ugly.

Why do they need a large water heater? Most small office buildings can get along just fine with a mini water heater under a cabinet somewhere.

Thanks, everyone. I was told that they are considering replacing the aged unit with a tankless, that would be the smart way to go.

And here's how you stick a drain into the drain pan in a brand new modular home!

Great pic Erby. Ifin it don't fit apply more pressure (and apply a lot of Great Stuff so the water doesn't run to the floor below).

Could someone please tell me what CSA L3C says?

I thought that only C3PO understood what that little guy says. []
