Just as I'm getting ready to winterize my pool, I got up this morning to water under the skimmer and upper outlet. Flooded under the deck, but can't find source of leak. Pulled steps out and dye tested as much as possible, still can't find it. Did notice that on the side opposite pump, which is uphill, is also very wet, so I'm thinking it might be there. Looking for any help in locating the leak in a very cold pool. I fashioned a tubing line ran it through the hole in the expandable stick and attached other end to a large syringe to deliver dye. Any suggestions, since there is a lot of ground to cover? Running water all night, as it has lowered under the lights and I'm concerned about collapsing. Thanks!
