Liner is Slipping

Hi - We just installed an overlap replacement liner in our 30' AGP on Friday evening. This morning, Sunday, we noticed that one side of the pool liner had slipped down in varying amounts. We left to run some errands and after returning home we found it had slipped some more leaving us with only a 3" overlap in some places. The temperature on Friday was 70 degrees but has since then fallen to 50 and is supposed to remain there for the next two weeks. We stopped filling the pool when we saw this and now the pool has about 1' of water in it.

What do we do now? Is it safe to keep filling it? If so, will the overlap be enough to survive winters and frost heave? Do we wait until the weather turns warm, drain some of the water and try to re-stretch it? Help!




Hi David. These are very good questions. If the liner had been tucked back into the pool, as described on the following page, you would probably not be having this problem.

You are very correct about the temperature and the amount of sunlight a liner receives as being important factors. If you were looking at 100 plus degree days ahead filling would probably not be a problem. The weather is not working in your favor. I would still continue, however, filling only during the hottest times of the day. Watch it closely, you can always drain and start over if it slips out.

Normally by the time a pool has a foot of water in it the stretching is done. The liner should be tight against the wall and should not pull down any more. If you always leave the pool completely full of water there should never be any further shrinking. Draining, on the other hand, could be a problem.
