In doing our research on the reasons most folks seek out pool demolition proposals, a common answer is that the pool is getting on in age, maintenance issues are happening more often, and leaks are a likely possiblity. In this day of severe drought conditions, tracking the loss of water from your pool may become a requirement from your local water supplier. The days of managing leaking pools are fast becoming a think of the past. I found this great description of how to tell if you pool is truly leaking versus the natural evaporation. A great DIY leak measurement tool is the “bucket test”. Here are the two main methods for determining actual water loss and whether evaporation or leaking is the culprit.
If you want to confirm a leak, try one of these techniques to double-check. If you suspect your pool is leaking, there are several ways to check.
Mark the water level of the pool at the skimmer. Use a piece of tape or grease pencil to mark the water level. Check the mark 24 hours later. Your pool should lose no more than 1⁄4 inch (0.6 cm) per day. Otherwise, a leak is indicated.
Place a bucket filled with pool water on a pool step (weight it with a rock or brick). Mark the water level on both the inside and the outside of the bucket. Make sure the water levels are the same inside the bucket as the pool water level outside the bucket. Check the mark 24 hours later. If there’s a greater drop in the line on the outside of the bucket, a leak in the pool is indicated. This test needs to be conducted with the pump on, then again with the pump off.
