Quick Answer

Some ways a pool leak can be detected are by observing if there is a noticeable drop in the pool's water level and looking for any cracks or wet areas around the pool that may indicate an underground plumbing problem, states American Leak Detection. A leak may also be present if there are other signs such as structural damage to the pool deck or air being in the pump or pool.

Air in the pump basket or pool can indicate a leak in the suction side of the plumbing lines. In this case, the leaking may occur only when the equipment is not running, notes the Pool Center site. Another cause for air in the pump can be an obstructed suction line. Structural damage to a pool deck can cause it to sink down, and can indicate that there is a leak in the underground plumbing.

Water loss through evaporation should not be more than 1/4 inch per day. A pool that loses more than this amount can be a sign of a pool leak. The following bucket test can detect a pool leak:

  1. Prepare the pool and bucket
  2. Bring the pool's water up to normal levels. Fill at least 2/3 of the bucket with water and put it at the pool's top step.

  3. Mark the water levels and compare in 24 hours
  4. With the bucket immersed about 6 inches in the pool water, mark the water levels both on the inside and outside of the bucket with a pencil or black pen. Operate the pool pump for 24 hours and check water level marks. If the pool water level is noticeably lower than the bucket water level, then there is a leak.
