Pool is just month old. Noticed in shallow end above built in bench there's a 10" x10" slightly bulging spot on liner close to water level. Feels like water behind the liner. I'm assuming most likely hole in liner? Would it likely be very close to the bulge? We have square corners where liner doesn't rest against pool walls and I don't feel water behind them, only in this one spot. See pic for birds eye view.

I don't expect it to be groundwater but is there a way to rule this out? If I raise level of my pool water, could the water bubble go away, and then I can conclude it is from ground water? Right now my water level is a little low I think, see pic.

That will dissappear as long as fresh water isn't introduced.
Do you mean as long as I do not add fill water? My kids were in pool splashing a lot yesterday. However the liner is tightly locked in that particular spot. On other end of pool, liner is pulled from wall in corner and I could see water splashing in there but again it's so far away. Our pb is supposed to fix that area.
