Hi. New 6 week old pool with two perfectly round sinkholes about the size (width & depth) of a golf ball I noticed yesterday.
This was a replacement for a same size older pool. Professionally installed, leveled, new sand, etc.
Do you think this is a leak, moles, wash out? I’ll get in today and test for leaks. Thanks!
