Hey guys just had a brand new liner installed with a new hydrostatic relief valve also replaced in the main drain at the bottom of the pool. This is an inground vinyl liner pool. Filled the pool yesterday half way up the skimmer and woke up this morning and the water level has dropped more than 3 inches. Anybody have any ideas as to what could be going on? Oh also to mention I had an entire skim coat of the bottom floor of vermiculite .
