Hi all, I have a pretty serious leak that I'm trying to diagnose and repair.
Few items:
Late 70s gunite pool, something like 30k gallons (irregular rectangle shapes, averages out to about 20x40). Don't believe there are any foundation or lighting leaks since the water level doesn't drop much when pool is sealed off for winterizing. Also doesn't drop as much when the motor is off.
Piping is designed where the suction and return have single pipes exposed outside and then split off behind a 4' retaining wall, so gaining access to individual lines is not simple.
Don't see any visible leaks with the equipment
Losing at least a few inches per day when the motor is running. I can fill the water level to mid-level on the skimmer and by the next morning my shallow end skimmer is barely holding on and the deep end will lose it by the next day. Eventually the water level drops below the skimmers if I keep things going.
I dye tested the return lines and skimmers. I noticed the deep end return line sucking in dye while the other two don't. I also ran the dye around the joint for the return line and no issues there, only sucks into the pipe.
I'm also assuming that the deep end return line passes by a tree I cut down when I moved into the house (was a massive oak only a few feet away that the builders very intelligently decided to leave to destroy the deck over time).
Tried to use a snake camera to look into the return line, but can't really see much.
I was in the process of SLAMing the pool, but I couldn't keep up with having to dump more and more chemicals to offset the fresh water I was having to drop in every day. Water is mostly clear, but I couldn't finish off the SLAM because of the frustrations with this leak. I'm wondering if there are any easy DIY ways to pinpoint the location without digging up the entire deck before I resort to having to call a professional and dropping a large chunk of money on this.
