so we set the pool up like 4 months back on a concrete slab, before we set the liner down we sweped well, maybe not well enough, if you go into the pool you can feel a few poking spots around the pool, must of been places in the concrete that had rocks or something that wouldnt sweep away and im guessing but not sure thats the cause of the leak....i know theres a leak cause theres always a 4 or so foot area and another thats like 2 foot around the pool thats wet, its not very big cause it takes like 5 days for the water to reach the top of the return and that or a little after is when i refill it......is there an easy way of finding the spots other then emtying the pool and looking? or should i just go to all the pokey spots and add large patches to them and see if that works?
