Many pool owners, especially if they are new pool owners commonly ask “why cover your pool in the winter“?
The simple answer to that is because you want to protect the pool and the people around you. The longer answer is that you could damage the pool, the pool plumbing and the water quality of the pool will diminish.
Winter is best known for ice and snow damage to pools in the northeast of the United states and also in some mid west states as well.
Ice is heavy and when it falls from trees into the pool it can cause major damage.
Possible Damage To liner
If you do not cover your pool for the winter time, there is a great chance that the weather will damage the pool liner. Ice and frozen branches can fall into the pool and rip or poke holes in the liner.
If your liner rips in the middle of the winter you can loose water and the pool could possibly collapse.
Pool Winter Safety Covers Protect The Pool
Loop loc, Merlin, and many other companies make safety pool covers.
During the fall and winter season, many leaves, acorns and dead branches will come off of the trees. They will land in your swimming pool if you do not have a cover on the pool.
Above Ground Air Pillow Prevent Damage
Air Pillows commonly called “pool bubbles” protect the pool from ice when the temperature drops below freezing. The above ground air pillow / bubble takes space in the pool water, so when the pool freezes the ice pushes against the air pillow ( for expansion ) instead of pushing against the pool walls.
Remove Equipment & Cover Filter System
You should always remove all drain plugs and also remove the pump, filter, salt generator cell, or chlorinator.
Leaving your pool filter system out in the snow can cause damage to the o-rings and the filter and pump. If water is left inside of the filter and the pump and the temperature goes below freezing then chances are you are going to crack the pump housing or the pool filter tank.
