Our winter pool cover is heavy duty vinyl (like the liner itself) and it has an edging that fits tightly into the coping of our pool liner/deck. I believe it's called a "lock-in" cover.
The fellow who put it on for us in past years is no longer in town, so we have a new pool company. Long story short: They've been here three times and the cover still isn't on.
Now they're telling us that (after 7 trouble-free years) the cover has "shrunk" and that's why it won't fit into the coping. (My opinion is that one person simply cannot put this cover on by himself.)
He is telling us that to get the cover on, we have to increase the water level in the pool so it can float on the water.
They have instructed us to raise the water in the pool a good 3-4 inches ABOVE the return jets.
I am VERY reluctant to do this for fear of damaging the jets/pipes. (We live in Canada and it's an inground pool with a SWG.)
Is it dangerous to leave the pool all winter with the water above the jets? Any thoughts?
Thanks for your experience/insight!
