I always suspected a small leak but a few weeks ago I started losing about an inch a day. That's crazy in humid Florida! Well I got the dye out and I watched it suck into the closest return to the pump. I figured I could tunnel to it, the concrete deck it only about 3 feet wide but what if the leak is not right at the pool wall and is farther towards the pump? Aw heck, I'll just call the leak guys. They can check the whole pool for any other small leaks and they will fix what I already found. It's only money, right? Wish us luck!
