Finding a Leak in an Above Ground Pool

21377318_sYou go outside to take a dip in the swimming pool and notice the water level has dropped overnight 2 inches lower than yesterday. You haven’t had anyone splashing around either, and it hasn’t been that hot, so a possible pool leak crosses your mind. So where do you start to find a leak that you really can’t see because there is no obvious puncture?

Pools plumbing system
The pool plumbing system can be the most common area for a leak in your swimming pool. So by testing the piping into your pool you can see if this is where the leak is coming from. To do this you can pressurize the pipe by putting the pressure up to 20 psi after blocking off the end of the pipe. If you see any leaks, mark where you see them. If it’s leaking at the joint, then take some Teflon tape and put it around the threads of the leaking pipe to seal it. If there’s a crack in the pipe or if it’s corroded though, then that section will need replaced.

Leak in the liner
First thing to do is to walk around the outside of the pool to see if any soil is wet on the outside of the pool. Wet soil is a good indicator of where a leak is. If nothing is showing, then get inside the pool. Check the liner for holes or cracks. You don’t have to drain the pool to do this; simply get as close to the liner as you can and feel for bumps, cracks or holes. Now when you find the leak, squirt food color in the water near the suspected leak. If the leak is in that location, then the food color will disappear into the crack or hole. By using an underwater patch kit, you can repair your leak too. Luckily, a liner in an above ground pool can last up to ten years if it’s taken care of properly.

To close, plumbing can be tricky. If you are unsure, get an expert.
