The winter months can actually be more expensive for the swimming pool owner believe it or not if the pool is not properly winterized. Things like frozen pipes or even frozen pumps and filters can cause you to have a huge repair bill come spring when the weather gets warmer. Another common thing that happens to many pools is that the cover blows off or comes loose during the winter months.

Making the right decision when something happens to your pool in the mid winter is very important for the swimming pool. Many people often say, “I will just wait to spring”, and ignore the warning signs or even worse do not respond to any damage caused to the pool or the cover during the winter.
Winterized Above Ground Pool
Things like leaving the pool cover off of the pool for 2 months after it blows off ca be bad for your pool. The more your pool is exposed to the harsh winter elements the more of a chance you have for damage to happen to your pool.

Many people also tend to forget that during the winter the pump & filter system is disconnected and the swimming pool water is not filtering. So with the pool cover remaining off and the sunlight hitting the pool water, this can throw off the total chemical balance causing your pool water to turn green or even black on the first warm day. Its always best to immediately get the swimming pool cover back on the pool as soon as it comes off.

  1. Hello –
    I have a 33′ round above ground pool. The people who installed it convinced me that it would be necessary for me to have a main drain in it. I had no idea at the time, so I let them do it. Now it is time to winterize my pool, and I have no idea what to do with the plumbing that goes to the main drain. I have heard from a few different sources to “blow out the line and add antifreeze” but nothing more specific than that. I don’t know how to blow out the line, or how to blow the antifreeze in there. I really just want to make sure we close it properly, but it seems no one can give me clear instructions (in laymans terms) on what to do. Please help!

  2. My in ground 18×36′ on ground pool is four years old this summer. The person who installed it has opened and closed it every year. Upon turning on the heater this year it sarted leaking out of the left side of my Hayward H400 pool heater. I called “John” who opens ans closes the pool he came and looked and stated that it was due to poor hemical balance. My pool is always crytal clear vaccumed every Friday and the water chaked with the strips as well every Friday and the chemical added. The heat exchanger coils have slices on the 3 of the 4 coils (on the left side of the heater facing) 3 of the four have slices on them no corrosion, dis-coloration. I feel that the heater was not drained properly and the lines froze and when I turned the heater on the expanded and started leaking. Can any one out there please give me advise on where to go or send pictures for validation. I have had two personnel come look at it. One a heater guy and one an actual pool service that both will swear this was the result of frozen pipes not corrosive pipes. please help.

    • Your pipes definately froze… You can get the lines repaired if they are copper or metal with a saulder gun. Otherwise you will have to replace the crackeed lines.
