    Solid Safety Cover Use

    Hi Folks,

    Im back once again and hoping to get some general information from the pool experts on recommended use of a solid safety cover. My questions are as follows:

    1) I have an inground 20 x 40 concrete pool (no tile) with a shallow end of 4 ft and a deep end of 8.5 ft. How low should i lower the water level? Some sites have said 12-18 inches. Furthermore, would this lowering start from coping/deck level or the bottom of the skimmer/weir opening?

    2) The cover sags slightly in the middle (I attribute this to a cover pump and some pooling of water) Im assuming this slight sag is normal or should I tighten the springs?

    3) Half of the springs are half compressed and the other half are fully extended. I figured I would leave some leeway for snowloads, is the cover too tight risking tears/damage or should I fully extend the rest of the springs? Any general rules of thumb for spring compression are welcome.

    I would have uploaded pictures but my file sizes were too large, is there any way around this or somewhere else I can post these photos for reference on this site? Thanks

    How do you control how much the springs are compressed?

    To just below the returns, this should be about 18" from the top of the pool.

    A slight sag is normal.

    3) Half of the springs are half compressed and the other half are fully extended. I figured I would leave some leeway for snowloads, is the cover too tight risking tears/damage or should I fully extend the rest of the springs? Any general rules of thumb for spring compression are welcome.

    Only compress the springs to about 80% of their uncompressed length, adjust as the straps stretch.

    I would have uploaded pictures but my file sizes were too large, is there any way around this or somewhere else I can post these photos for reference on this site? Thanks

I think the practices regularly espoused on this forum (especially the BBB method) are outstanding; however my comments will be often oriented towards the goal of getting it done, and getting it done right now!

    Basically you use a hosting service like Flikr or Photobucket and then link the pics to the thread.

    Re: Solid Safety Cover Use

    Thanks so much to you both! That really clears things up, the only other thing I wanted to do is upload a couple pictures and make sure the cover isnt sagging too much and that the water isnt too low since I made the recommended adjustments to water level and cover springs. Your expert judgment is appreciated
