The pool has been setting for years at this point the last owner attempted to fix it it lasted one season, due to a liner issue. Since its been raining here in Iowa since winter I went ahead and moved the pump filter and installed new 2 inch piping to the pool, new strainer,working on dual drains now. I have emailed SPP about the pool corners and they contacted the liner manufacture and will make sure the liner is made correctly, was debating changing the corners they are rectangles that are smaller on the bottom then the top the liner was opisit, I will try to post some pics. the pool has a Vermiculite bottom and walls at least it did, it is all broke and falling and the repairs from before are horrid to say the least. I might just use a sand-grout mix since I am unable to find bulk Vermiculite and to have that much shipped here would be pricey. Here a some pics before I started.
