this will be the second time I ever close a pool, it was installed last year and last year I installed a gizmo in the skimmer and the pool installer watched me close it to be sure everything was done correctly, which it was. no issues this spring when opening it.
Thinking about doing it a little different this year.
Last year we did not lower the water level at all, it was half way up the skimmer and we kept it that way.
any harm in doing the following?
I am thinking of lowering the water level to just below the skimmer, any harm in doing this? I know fiberglass pools need to always have water in them, but will lowering it 12" do any harm? This will make it easier to evacuate all of the water out of the skimmer and pipe going to the pump. I can blow it out completely, I also use a plug/plate to seal the face of the skimmer. it worked great last year so plan on using it again. Rather than using a gizmo, since I can completely blow out the skimmer and line would I be better off once line is blown to pour a gallon of antifreeze in the line and then plug it with a return cap with o-ring seal? or am I better off using the gizmo? Once capped I would pour another gallon into the skimmer tub and also place a plastic soda bottle half filled with sand to absorb any freezing if there was any. all 4 returns will still be below the water line so I will blow those out and cap as normal then pour a gallon of antifreeze in each line for added peace of mind.
Thoughts on lowering level below skimmer and using plug instead of gizmo?
