Well posted before about liner wrinkles got them out then noticed water leaking with pool off used scuba gear found that the liner had pulled out from around one of my two drains .. It also has a little tear on both sides at 3 and 9 oclock about 2 or 3 inches long .. Can I patch this I have extra liner when the pool was installed 3 years ago. I think I can get the liner back under the trim ring under the drain that would leave two patches to mend .......... Or do I need to drain pool completly and stretch the liner ... Pool company that built my pool said 3000 to replace liner.. water table to high caused it to happen.... Dont wanna have to replace the liner at 3 years old... pool is 18-41-16-28 true L - 9 foot deep
