I have a 18by36 inground pool Loosing about 1 1/2 in or so A day thought I would let it drop. Dropped just below skimmer. Dye test using dye syrup mixture around skimmer has had no result as water has fallen. I have been all around the pool for hours daily looking for leaks. My question is if I fill the skimmer basket area with water until it holds should it hold if there is no leak? We ran a pressure test and the skimmer line would not hold pressure. There was no air comming into pump basket when pool was leaking. We are now running from the main drain. Would there always be air with a suction side leak? Not using skimmer for days and having windy weathering need to vacum. Can I attach pole vac to main drain?
Thanks for reading.loosing mind from this anigma.
