Ty- Are you talking about a leak in the plumbing of the pool? Sounds like. If Fantaj is looking for a leak in the vinyl liner, your idea would probably work also, but not sure how. There is a commercial leak detector that pool companies use to find liner leaks. Had to call them once for mine. They stick a probe in the ground and scan the liner with another element on a pole. When they find a hole, a signal (sound or meter or whatever) goes off. Unit costs about $1000 so recommend calling pool company. I think they charged $125 but probably higher now.
