After a bucket test it seems i have about a 1/8 - 1/4 leak per day on top of the evaporation. I have not yet had a pool leak company come out yet but I have been observing one thing. We have barely had any rain over the last few weeks and yet my sump pit is filling up about half way each day after pumping it daily. Not knowing much about the plumbing aspect of my pool to me it SEEMS like water is getting behind the liner from the leak and causing it to go towards the sump pit. How likely is this to be a decent hypothesis or is it also possible there is a plumbing leak somewhere underneath that this could be a major issue?
