    Are diagonal and side wrinkles in auto cover normal?

    Here's a couple of photo's. I had the installer return to check on this and he said that all alignments were good. My water level is even with the ledge that the front bar sits on when it's open. The front edge also stops square with the pool when open and closed. It's hard to see, but in the first photo there's wrinkling along the entire right side where it comes up to the track but you can see from the photos that the left side has an unwrinkled nice radius. The cover is new and hasn't seen warm weather yet. The installer thought there was nothing to be concerned about and it would get better from warmer weather.

    From my past experience when there is a wrinkle in a cover like that something isn't square. A cover when installed correctly should have no diagonal wrinkles.

    I get the same thing, I can see when the cover is fully open or closed that it isn't perfectly square to the pool. The ropes that control the opening / closing could be adjusted to eliminate this, as it was square a while ago, it doesn't seem to effect anything operation wise.

    As for the wrinkles the cover needs to have slack so that when a load is placed on it it can sink into the water some to support the weight, if it was tight the load would be applied to the side rails which are not meant to take a lot of force.

    I guess they should be adjusted as on of my ropes broke the other day, they replaced it under warranty, but now I would be cautious if the cover is more than 1" out of square.
