A neighbor of mine has one of those above-ground swimming pools that is
basically just a huge bag of chlorinated water. It has a slow leak in the
floor somewhere. Her question to me: How do we find the leak? It could be
something really small; and the fabric of her pool has that speckled design
that makes blemishes hard to spot. I suggested dropping some dye into the
pool and hoping it’s pulled towards the leak, but this doesn’t actually seem
very likely, the pulling being so slow that the dye would all have
dissipated before the direction of flow became clear. So… how does she
find the leak? Any suggestions to olimu@optonline.net, please.
