4 Ways To Check A Pool Liner For Leaks

Pool leaks are bad news for your garden as well as your wallet. Having to top up a leaky pool is a waste of money. Chlorinated water may damage grass and plant roots if it drains into your garden. Here are five tips for checking your pool liner for leaks.

Tip #1. Don’t Forget Your Warranty
The best way to check is to get someone to do it for you. See whether your pool liner is still under warranty. Most firms offer protection for a decade or longer against their pool liners leaking. If you believe that water is draining from your pool more quickly than usual, simply call up the supplier or contractor who fitted the lining. They will come and take the guesswork out of the process.

Tip #2. Rule Out Evaporation
If you wake up one morning and discover that your pool’s water level has dropped several inches overnight, you know you have a serious problem. The trouble is that with changing weather conditions it can be quite misleading to rely on the rate of water loss alone to tell whether you have a leak. A couple of inches per week may be normal due to evaporation but an unusually hot period will result in more evaporation. To check this, fill a bucket with water and put it on the pool steps or the top rung of the pool ladder. As the bucket is submerged, the water will remain at the same temperature as the pool water. This helps you to gauge whether the pool level is dropping faster than the level of the water in the bucket.

Tip #3. Rule Out Your Pump And Filter System
If your pool liner is leaking and you don’t have a warranty, you will need to do a lot of work yourself. Just a tiny perforation can cause several inches of water loss per day. Your pool has two distinct systems. One is the return jets that push the water back into your pool and the other is the skimmer and the main drain that suck water out of your pool via the suction jets. To rule out both of these systems as the cause of a leak, turn off the pool filter, remove all return fittings and place rubber plugs into them. Do the same thing with the skimmer. Open the skimmer, remove the basket and use rubber plugs to securely plug all of the suction jets. Make sure the system is switched off and continue to monitor the water levels. If you continue to lose water, you know that nothing is wrong your pump and filter system.

Tip #4. Pinpoint The Source Of The Leak

After a few days of observation, the bucket method will give you a fairly clear indicator as to whether you pool liner may have a leak. To confirm this you can use food coloring to try to tell where the leak might be. Food dye will not stain your pool tiles, grout or concrete. This method works by the fact that water leaks will draw the food dye towards them. If your pool liner is leaking water, the dye will show up the direction that the water is escaping in. Walk around your pool and put drops around the perimeter. In around 30 minutes or less, you will be able to follow the trails of food dye to locate the source of the leak, if any. If you can’t find the rip in the pool liner, you likely have an issue with a pool light or a gasket around the step according to one swimming pool company in Westport CT. You’ll need to call a professional who will go in with scuba gear and do underwater patch jobs on all the fixtures and fittings where water may be leaking.
