Leak Detection

The Underground Detective uses highly sensitive acoustic listening equipment in conjunction with helium to locate water leaks in fire mains, potable water, chiller systems, sprinkler systems, swimming pools, and concrete slabs.

Swimming pool leak?

Try the simple “bucket test!”

  1. Bring the pool water to its normal level
  2. Fill an empty bucket with pool water to about one inch from the top of bucket. (By filling the bucket close to the top you are ensuring that air movement over the surface of the bucket will be similar to that of the pool.)
  3. Place the bucket on the first or second step of the pool. To keep it from floating away it may be necessary to place a few bricks or rocks in the bucket. (By placing the bucket in the pool water you are ensuring that the water temperature of each will be similar).
  4. Mark the water level inside the bucket.
  5. Mark the water level of the pool on the outside of the bucket, on the pool wall, or skimmer faceplate.
  6. Operate the pool for 24 hours as it had been operated when a leak was first suspected.
  7. After 24 hours, compare the two levels. If the pool water (outside mark) goes down more than the inside water level, there is probably a leak.
