I have a 22K gallon inground gunite pool that is leaking. I am in the bay area, and the leak seems to have started since the recent earthquake we have a few weeks ago. I am trying to figure out the source of the leak. The pump is off and the leak did not stop at the skimmer. So I am thinking it could be one of 4 things:
1. I have 2 cracks in the pool shell, that could have widened due to the earthquake
2. The pipe connected to the main drain is leaking
3. There is a leak in the return line (I plugged one of the returns. Need to get another expansion plug for the other one)
4. Pool light niche
I suspect it is the crack in the pool that might have gotten wider. I will run a more through dye test today. If that's the cause, is there a simple way to patch that (e.g., A+B putty)? The pool guy is recommending I replaster and move to fiberglass (estimated at $8K cost). It is an old pool and may need replastering soon anyway, but not sure I want to make that investment to solve for a leak.
