Leaving the pool uncovered for the winter is a choice you may want to consider, if you have had problems in the past. The drawbacks of not having a cover over the winter are that debris and leaves may get into the pool but a simple leaf net will help. Also even if you do not cover the pool dropping the water line lower than the returns and skimmer is a must before the water freezes. For more information or if you would like to have your pool closed, contact the long island swimming pool company or visit our showroom at (631)-543-1177, 1015 W. Jericho Turnpike Smithtown NY 11787.
