Water Loss in Swimming Pools

The other day a friend of mine was walking through his urbanisation and saw a large volume of water flowing down the street. Curious, he followed the torrent up around the corner and discovered its source. A huge volume of water was cascading down over a large boulder retaining wall in the back of a home. Upon closer inspection, it was evident that the swimming pool had sprung a leak!

The potential for catastrophe from pool leaks cannot be understated. They can undermine foundations of pools and homes, causing decking to shift and move. If left unchecked, they can affect properties adjacent to the pool, or downhill as was the case with this leak. Most leaks are not as obvious as this one was, and that’s why if you suspect your pool is losing water, it’s time to do a little detective work.

First, look for obvious signs. Is there water around your pool equipment? Are there wet areas in your yard that never seem to dry out? Is your auto-fill constantly running? These telltale signs may indicate a leak.

Unfortunately, most pool leaks are not so identifiable. Due to poor construction practices, leaks often occur at pipe penetrations in the pool shell, around skimmers, inlets, and lights.

Another way pools lose water is through evaporation. Many pool owners are not aware of the significant effect evaporation has on their swimming pool. During certain times of the year, evaporation can increase due to heat, wind, and humidity. Certain types of pools can lose more water than others as well. How is that possible?

Consider the vanishing edge type of pool. Water loss through evaporation is reflected in the catch basin, as the water level in the main pool remains at a constant level. The catch basin also reflects it’s own water loss through evaporation. The small surface of the catch basin makes the effect quite dramatic! In addition, a catch basin that is undersized for the pool it supports makes the problem appear even worse.

Yes, water loss in swimming pools can’t be avoided entirely, as in the case of evaporation. However, pool leaks CAN be addressed, saving you money and the potential of damage to your pool and property. We utilise equipment that can absolutely identify how much water your pool is losing, differentiating between actual evaporation and water loss due to leak(s). We use non-invasive procedures to fix the problem, with the ability to identify and correct issues without draining the pool. Water is a precious commodity. If your pool can’t hold it, give us a call!
