Pool Leak Detection

All our dedicated swimming pool leak detection technicians are fully qualified divers and are trained to the highest level possible to detect your leak.


We only use the most up to date leak detection methods including electronic, sonic, CCTV, Pressure testing and hydro phonic leak detection of your domestic or commercial swimming pool.

We can find your leak no matter how small with our new thermal imaging system also used by fire-fighters to locate people in burning buildings.

Your pool will naturally lose some water to evaporation, some to splash-out and some to backwash wastewater. You may also gain water from rainfall.  Our rule of thumb is that if you're routinely adding more than two inches of water to your pool per week, you may have a leak.  It is worth spending some time and money to repair.

Do I have a leak?


First, make certain that you have a leak. Mark the height of the water in the skimmer or tile line with a piece of tape or a pencil mark. Watch the water over several days to see if there is a problem. Evaporation can play a significant part of water loss and is increased when the pool is heated. After it is determined by careful observation that there is a leak in your pool contact us. By asking a series of questions we can likely determine the nature of the problem by the symptoms your pool is exhibiting and recommend the next step to take in fixing your problem. Here are a couple of things you can do yourself prior to calling us to determine if there is a legitimate leak and possibly save some money for an unnecessary service call.

Evaporation Test


Fill a large bucket and put on the second step of the pool. Fill the bucket to approximately the same level as the pool. It may be necessary to put something heavy in the bottom of the bucket to prevent it from floating away. Mark the level of the water inside the bucket and the level of the water in the pool. Monitor the water loss over 24 or 48 hours and compare the difference in water loss. Although not foolproof this gives an indication of whether the pool is losing water from a leak or evaporating. Factors such as heater use and slight differences in water temperature in the pool and the small volume of water in the bucket can skew the results of the test procedure especially when the water loss is marginal. Most pools lose 1/8" to 1/4" of water per day for evaporation. Evaporation is also seasonal. Humidity, temperature, wind, pool water temperature and heat from the sun will all effect evaporation.

Where is all this water going?


The same place it does when it rains, into the ground. Unfortunately the ground under your pool, which in time this water flow can undermine your pool deck and cause structural problems that can eat deeply into your pocketbook. In a vinyl pool an unrepaired leak can wash out the sand or vermiculite under the liner. Sometimes it can turn into an unrepairable problem if ignored for any length of time. Just refilling the pool continually because you have well water or can afford it is not a good idea. A concrete pool can actually rise and float out of the ground when it becomes empty because of a high water table. If you don't think concrete can float, there are many barges that were constructed during world war two that float.

Can a small hole cause all that water loss?


A hole that a pen can be stuck in can easily account for a loss of two inches a day. Several holes much smaller than that can account for much more of a water loss. Also a liner pool with holes that are not visible to the eye can leak through the material. After years of chemical exposure, ultraviolet light and fluctuating PH the vinyl material breaks down and becomes porous. A liner in this condition can lose a significant amount of water everyday. As the liner weakens with age the amount of force used to clean the liner when it was new and resilient can be enough to puncture the material. If care is taken when vacuuming or brushing the pool this type of damage can be avoided.

How does my leak get repaired?


If the leak is in the structure of your pool,  I will actually dive underwater to determine its location, size, and best method to stop the leak.  Leaks in the structure of a concrete pool can usually be repaired with a various combination of materials. Not every leak is repaired in the same method. This is determined by size, severity, location, and complexity.  Vinyl pools can be patched underwater. Underground plumbing leaks are found wby pressure testing and Ultrasonic Detection. Don't ignore your leak problems over the winter. This could mean disaster for your pool. I can actually do the repair during the winter.  Let us help you protect your valuable investment in your pool. Your pool is supposed to be a source of enjoyment not anxiety. I can help.
