It leaks.
I think we figured out where - the plumbing part I didn't think would be so 'tight' fitting as it was supposed to be.
Not positive yet, but that's what it seems like it is.
So have to figure out where it is and then figure out how to fix it as that piece IS part of the drain and the only way to remove/replace it is by taking it out, which means a bigger hole in the liner so a new drain will be hard to find to fit that.
So hopefully we figure out a different way to fix it if that is indeed where it is leaking from.
On the bright side, it isn't holding anything up - pump and liner for the filter have to arrive yet LOL
