How must a water heater relief valve discharge pipe flow to its point of discharge?
a.Uphill to an overhead receptor
b.Level with no slope
c.Downward, draining by gravity
d.Through a pump to grade
Giải thích
The discharge pipe must run downward from the valve so it drains completely by gravity to the point of discharge. Any low spot, trap, or upward run could hold water and freeze or block the line. Continuous fall keeps the relief path clear.
