Thanks. I drained it and flipped it, but had second thoughts about digging in from below. When flipped we did not know the location of the leak (tub has been empty for awhile). It was only after filling that I could see water dripping below, and in the general area of a jet. I had hoped to access that location with water in the tub to verify the leak....without draining , flipping , digging, flipping, and filling...
looks like I"ll be sawing (carefully) into the side at the jet. BTW, I did try the food dye trick, but it is a slow leak and hard to tell if any dye actually went in...
thanks for the suggestion. Any special tricks about cutting into the skirt (other than to be careful)?
