Hi everyone,
I've recently moved into a place that has a inground concrete pool which has a leak. Water leaks from all around the coping mastic (rubber movement joint) when the pump is on. Water usually appears about 1 hour after the pump has been turned on. the Pool has a single suction skimmer box to pump, then via cartridge filter to Chlorinator the pipe splits into 3, (fountain, Polaris via extra booster inline pump line, and a single return line which splits into two return outlet pipes somewhere and goes into the side of the pool and returns water to the pool.
So far I've blocked off one of the return lines and this increased the water leaking out of the ground around the pool. I've isolated the Polaris line as I have a three way valve and also the fountain line as well. This leaves only the return lines or the suction skimmer line back to pump as possible leaking pipes.
I've hired a pool leak specialist who has asked me to run leak tests before he attends. Pump on, pump off, evaporation and also blocking off return lines etc.
So what I'm concerned about is the leak specialist uses sonar and he stated the test is 90% accurate in finding the leak through the ground. He also does pressure testing of the lines. My issue is if it's leaking after the Y in the return lines where they split into two and there is multiple leaks he will only be able to find 1 at a time. I've since found out other leak detection people use a mix of sonar and inspection cameras. Can anyone give me advice on which one is better and more accurate?
Also can anyone suggest to me what I can also do to try and narrow down where the leak is coming from. In the picture you can see the water from the mastic seeping through.
If and when the leak is found I've been told it will require a replacement to the leaking part of the pipe which requires removal of tiles and digging up the ground to expose the pipes. I've also found out there is companies that do pipe lining with a epoxy resin. Is this suitable to avoid having the ground dug up?
