Q.  How do I detect a leak in my gunite pool? 

A.  Finding leaks in a pool is a difficult task and should be left to a trained professional.  Leaks are rarely visible to the eye, often seeping into the ground unnoticed and undetected.  Memphis Pool has simplified leak detection into three-step process: 1) gather and evaluate information; 2) test for structural and/or plumbing leaks; 3) repair leaks.


Step 1.  Gather and Evaluate Information

In gathering and evaluating information on your pool, a trained Memphis Pool Leak Detection Expert will first determine such factors as the type of pool, pool system, and age.  Then, we will visually inspect specific aspects of the pool.  Next, we will perform a bucket test to determine how much water is being gained or lost due to rainfall and evaporation.  In addition, we will perform a pump on/off test, which provides an indication of which part of the pool is likely contributing to the primary leak.  Lastly, we evaluate this information to determine the best way to proceed into Step 2.


Step 2.  Test for Structural and/or Plumbing Leaks

Based on the information gathered in Step 1, your Memphis Pool Leak Detection Expert will decide whether tests in the structure or the plumbing of the pool are necessary. 

Testing for plumbing leaks

This consists of pressure testing and leak pinpointing.

Pressure testing checks the integrity of the plumbing.  It involves blocking off exposed openings of a plumbing line and putting the plumbing line under measurable pressure.  A pressure drop indicates a leak.

If it is determined through pressure testing that a leak is in a line, then the location of the leak must be pinpointed.  A specialized electronic listening device is used to ascertain the specific location of the leak.

Testing for structure leaks


This involves careful inspection of the pool’s interior, as well as the fittings, skimmers, and light fixtures built into the pool’s structure.  This process is time-intensive and generally uses a combination of processes that include dye testing and underwater diving equipment.


Step 3.  Repair Leaks

Once leaks have been located, the repairs can be performed.  Repairs of leaks in areas that are easily accessible are often repaired quickly and inexpensively.  Leaks in hard-to-access places, such as plumbing lines or fittings under the ground, deck, or pool, will require considerable work and expense.

Memphis Pool will provide a written quote detailing the work and costs involved to repair the leak located.  Alternative options, to repair or not to repair, can also be provided and examined.
