Joe, I was born and bread in Tenafly - come Tuesday, or whenever this %^*^%&^$#^%$ rain stops, do as Al said and look around the plumbing for drips - please remember to check under the pump!. If it's not a plumbing issue, it's a liner issue and we can tell you how to check the liner for leaks

In the mean time, just run a hose into the pool so you don't get too low on the water level (of course with the rain we're expecting - the hose probably won't be needed)
