Hi, I have a replacement vinyl liner scheduled to be installed this week but the forecast calls for rain, heavy at times. The liner installer (one of the largest pool companies in the country) insists they routinely install liners rain or shine. My understanding is that this can lead to a whole bunch of problems including wrinkles and misalignment, not to mention make it difficult for the installers to maneuver the liner and get it properly seated in the track. How big of a deal is it that they are installing this in wet weather?
