I've tried to find out a question about the proper way to close our pool. We live in Ohio and often get very long spells of freezing weather over the winter. I have read the forum about adding antifreeze to the plumbing and blowing out any water in the pipes however I'm wondering if this is needed in all cases? Our pool was built with an "access hole" under the decking as displayed below.
Is simply draining any water from these pipes and capping off the returns enough to prevent any damage or should I still use antifreeze as added insurance? I'm worried about the winter again this year, as last year was a major pain. If only I could be lucky enough to have mid 70 degree weather year round.
