On a small hospital renovation during plan review, a water-heater relief line rises after leaving the valve and terminates with a threaded cap; what is required?
- Gravity discharge to an approved point
- BInstall a shutoff valve for testing
- CConnect it to the cold inlet
- DLeave the cap loose
Why A is correct
A relief line must not be blocked, trapped, or valved because restriction can prevent safe pressure or temperature discharge. The best answer is therefore “Provide an unobstructed gravity discharge arrangement to an approved termination.” The other choices either address a different system, rely on an unsafe shortcut, or make a conclusion not supported by the stated facts.
