I have a rental property with an in-ground pool. Last year my tenants failed to let me know that water was leaking out of the pool. They kept filling it up and once the pool was closed in the fall it all drained out. It wasn't until the following spring I found out there was no water in the pool upon opening.
I have a pool company that opens and closes the pool each season. They were able to find the holes in the liner, patch, and slowly fill the pool back up. Now I just found out that the foundation of the pool is shifting and I wonder if this problem is due to the pool sitting empty for so long.
Also want to mention we live in Canada where the ground freezes over the winter and the pool sat empty during the long cold winter. I've attached photos of the pool. Can someone tell me if this could be the reason for this issue?
