We just had our liner for our IG vinyl pool installed last Saturday the 19th. Our PB worked the bead of the liner in the track slowly around the pool while smoothing out any wrinkles as he went. He then installed three equally spaced vacuum nozzles between the wall and the liner and used duct tape to seal.

Water was added while he and his crew were in the pool smoothing out any wrinkles they could find. Once he was sure an area was wrinkle free they removed each vacuum and tucked the bead in.

It worked very well, not a wrinkle to be found.
