Question 3693 Deck General

70% to pass

When fire pumps are used for other than firefighting service, each pipe connecting the other service (except for branch lines used for deck washing) must have a _______________.

A check valve installed in the line

B regulator in the line set at 125 psi

C quick disconnect union within ten feet of the pump

D shut off valve at a manifold near the pump

AI Explanation

The correct answer is D) shut off valve at a manifold near the pump. The reasoning behind this is that when fire pumps are used for services other than firefighting, such as deck washing, each pipe connecting the other service must have a shut-off valve installed near the pump. This allows for the isolation of the non-firefighting service, ensuring that the fire pump can be dedicated to firefighting if needed. The other answer choices, while potentially relevant in other contexts, do not specifically address the requirement for a shut-off valve near the pump when the fire pump is used for non-firefighting purposes.
