Hi, recently went through a freeze and during the thaw, the plumbing line for my cleaner, which is plumbed on its own valve, sprung a leak. This is confirmed as when I bypass the booster pump, leak stops. Slow dribble with pool running and gushing water with booster pump on. The leaking water was coming up between the pavers and the coping all along that drawn red box in the picture. I’m curious as to how these lines are generally plumbed. In the picture, is the white line how the pipe would usually enter the wall or is it possible it’s running parallel to the pool wall there or under the coping (yellow line)? Of note, there is some heaving of the pavers near the top of that red box. Also some of the leaking water seemed to be traveling under the pavers and exiting at random places above deck. There is also a crack in the coping (pre existing) close to where the water originally started leaking from.

Leak detect guy came out and said he’d probably dig where the green circle is, but he only did a pressure test and didn’t listen for the leak. I’m more inclined to think it is closer to the wall and where the pavers have been pushed upwards.

The pool is running fine and holding water level, as long as I don’t run the cleaner which I can’t anyways because it’s been bypassed. This is the first pool I’ve owned (only been a few months) but it was built in 2016.

Open to any thoughts and suggestions as the repair is a month out, but I’m getting impatient and may tackle it myself

Welcome to TFP.

There is no predicting how the pipe was run. You need to pull up a section of pavers and maybe you will see a wet area bubbling where the break is.

Do you know what is under the pavers? Dirt? Concrete?

Thanks for responding, I pulled one today, lots of hard compacted dirt and rock gravel so far, kind of a pain to get through. Considering pulling one closer to the pool wall near the leak exit point also
 
Dirt and gravel is better then finding concrete under the pavers.

I would pull a section of pavers and run the booster pump and see if a wet spot in the dirt appeared.

They probably ran it the shortest possible route to the equipment pad. It could be straight or could turn parallel.

That’s odd a freeze would break that pipe buried like that, I guess if it’s too close to the surface it could freeze but those are usually buried a bit deeper than the frost line in Texas.

+1. They usually go immediately down, starting at an already ok depth for short term freezes.

But as said above, there's no telling what was done or why, especially in a warmer climate that hadn't froze in 25 years before a couple years ago.

I thought the same thing about why it could have froze. I am guessing what happened was there was probably a small leak, and some of the water that escaped upwards against the pool wall froze during the 3 day cold snap we had, which might also explain the pavers heaving in that area. it wasn't until it got sunny and warm that the leak became obvious.
