I got the tfp email today and saw the recommendation to lower the water, I haven't done this in years. I used to, then I read somewhere not to. I leave the water at the normal level. I blow out the lines, for the returns I took an elbow that screws into the fitting and a little hose that remains above water level, blow the line, poor in antifreeze, and then cap that for the winter. At the skimmer I have a gizmo that opens at the top, I blow the line and let the water out of that, anti freeze, then cap it. I also use a mesh safety cover. This does let in water over the winter but I never had an over flow problem. I feel that the higher water level tends to support the weight of accumulated snow. What do you think? Thanks.
