17,000 gal vinyl IG pool.
losing about 1/2" + - per 24 hr period
keep it covered practically all summer
no visable leaks on equipment pad
plugged suction side one night and return side another and still have leak.
went around to every flange with red dye, no signs of leak
did the bucket test overnight no real evaporation
pool held a basic water level all winter ( i say "basic" because we did have rain etc)
so my next step is to let it go till it stops and check the liner at that level? anything else?
