Re: Closing a SWG pool with sunshelf and automatic safety co
FIrst, I don't recommend using the auto cover as a winter cover. It will shorten the cover life and possibly the track life, depending on where they are installed. The lack of "give" when a snow load sits on it can cause tearing. I do recommend using a safety cover that extends beyond the spool by at least 9".
If you have waterline tile, you must lower the water or risk tiles popping off or cracking. Any tiles on the floor of the sun shelf will be fine. Ice expands up and out, not down in a pool. If you have a liner pool and no waterline tile, you don't need to lower the water.
If your sun shelf has bubblers, they must be blown and plugged. They are too close to the surface and would be at risk from freezing.This may mean getting wet. Waders and a rain coat are helpful if the water is cold. The use of a deflector, such as a skimmer lid to direct the bubbling water away from you is often helpful.
Air is typically blown in the lines, either with a blower or a powerful shop vac, from the equipment pad out. I use an assortment of expandable rubber plugs to seal the lines I can reach. Bottom drains are typically air locked.
I strongly urge you hire a service. The money spent is nothing compared to the damage ice can cause to the lines and equipment.
