How do I know if my pool is leaking?

You have a leak if you have to add one inch or more of water each week. The first thing to do is carefully mark the pool water level, wait 24 hours, check it again and measure how much it dropped.

Normal evaporation rate in Southern Ontario during the swimming season is 0.4 cm or 1/8″ daily. Covered pools will lose less and pools with waterfalls, vanishing edges or pools heated far above the surrounding air temperature will lose more.

Where is all the Water Going?

Leaking pool water disappears into the ground and is often not noticeable. Unfortunately in time this water can undermine your pool and deck and cause structural problems that can cost thousands of dollars of damage. 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.

How Can a Hole Lose So Much Water?

A hole less that 0.3mm can easily account for a loss of tens of cubic metres of water 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.
