Fixtures & Water HeatersPregunta 77 de 120
A laundry standpipe for a residential clothes washer is roughed in with the top of the standpipe 14 inches above the trap weir. Is the installation acceptable?
a.Yes, any height is acceptable as long as the trap is vented
b.Yes, 14 inches is within the allowable range
c.No, the standpipe must extend at least 18 inches and not more than 42 inches above the trap weir
d.No, the standpipe must be at least 24 inches and not more than 60 inches above the trap weir
Explicación
A clothes washer standpipe must be a minimum of 18 inches and a maximum of 42 inches above the trap weir, so 14 inches is too short and the discharge is likely to back out of the pipe. Height is regulated regardless of venting, so the first choice is wrong. The 24 to 60 inch range in the last choice is not the code window.
