Hi
Here in the frozen north, snow season ended ! The sled dogs are retired for the summer and it's time to open the pool!
So, after taking the cover off and recovering from getting knocked over by the sulphurous stink, I noticed that the pool liner is sagging. It hasn't slipped out of it's track, but it is baggy and has more folds than I can count. What to do? We only have a 2 and a half month pool season, and since I drained the pool today, it seems like a good time ( after cleaning the muck out) to adjust the vinyl liner....but how to do that?

Any advice would be very helpful.

Only in Ontario...
