Thiết bị & Bình nước nóngCâu 181 / 360
A water heater drain pan must have a minimum depth of:
a.1/2 inch
b.3/4 inch
c.1 inch
d.1-1/2 inches
Giải thích
The pan must be not less than 1-1/2 inches deep so it can hold a reasonable volume before the drain carries water away. A shallower pan would overflow quickly. Depth combined with a proper drain keeps leaks contained and visible.
