    Water Loss Over Winter

    Hi all,

    Just got my pool filled back up to operating level last night and plan on starting her up when i get home this evening.

    I just wanted to run something by some of you.

    When I closed up last fall I drained the water down below the returns and removed all pvc piping etc. from the pool/ filter and stored it inside. I then placed the winter cover on it. I did not regularly keep the cover drained off this year in hopes that the water on top would help hold it down and keep the wind from blowing it about causing damage that I experienced last year.

    The thing is, there was only a little over a foot of water left in the pool. Could the weight of the water on top of the cover displace the water in the pool enough to force it to drain that much out through the disconnected return?

    Hmmmm,

    Mike

    It's hard to say but it is possible. The cover would have to be really full and sitting near the bottom for that to happen.

    Yep, possible but not probable. I'm preparing myself to find a leak.

    Did you plug the skimmer pipe and the return?

    If not, the ice on and under the cover might have forced the water out of them. (ice is less dense than water)

    I did not plug them. Not sure how much ice we had here in Alabama. It was mild winter for sure. The cover had a good bit of water on it at times.

    Re: Water Loss Over Winter

    My problem here is that the cover isn't perfect, water can pass from one side to the other. Last fall I siphoned water off a couple of times, the pool level went down. It seems that pool water passes through the liner and I was pumping it out. So, I left it alone. The overall level stayed just below the skimmer.
