Homeowner Replacing Skimmer Box / Massive Water Lost - Question

Hello,

Long story short, we've had air bubbles in our lines for awhile now so after replacing the o ring on the pool pump which did not solve the problem, we dug up the backyard. We saw the original skimmer box has plumbers putty on it preventing the use of a barracuda so we dug underneath to see if the pipe was leaking. It was, and the skimmer box is shot along with some of the pipe underneath the patio deck. Both are going to be replaced. We have to wait for the hole to dry out, wall it up with plywood to prevent cave in, rent a concrete saw, cut it out and buy a new Hayward skimmer box, install the skimmer and new pipe.

Question: We drained the pool water line to be even with the bottom of the skimmer box and let evaporation do the rest. When we woke up this morning, the pool water line was 5.5 inches below the skimmer box and I have no idea what happened. I took a couple of pictures and posted to view. Any thoughts on where all the additional water went? Do we have another leak somewhere?

The pool has a floor drain that we have no idea if it works or not (skimmer has two holes, pump and main floor drain I assume). We've never seen the main drain work (has no suction, not sure if its suppose to??)

The pool is about 15-18 years old (concrete). The home was foreclosed on twice by previous owners and we've brought the pool back to life. Its been working fair for the last 4 years with the bubbles (now determined to be leak).

Thanks!!

:wave: Welcome to TFP!!!

The fact that the water stop dropping right at the return jet makes me suspect either a leak in that pipe or where the pipe enters the pool.

Thanks for the reply. I took two more pictures and will have to make links for them as I ran out of cap room. Based on what you said, it probably is one of the other pipes leaking too.

So it could be leaking at the interface of any of those jets that are right at the water line. Try filling the pool an inch or so and putting some food coloring by each and see if it gets sucked into the wall anywhere.
