Winter Safety Cover on a swimming pool

How do I winterize my in ground pool?

Making sure your pool is properly winterized is important in maintaining all of your equipment and plumbing. Costly damage can occur to your pool or pool equipment when your pool is not properly closed during the winter months. You want to be sure that everything is ready for the deep winter freeze that we experience in the Northeast.

  1. Add Chemicals – First
    The first thing you want to do is add chemicals to the pool: shock, alg
    aecide, and a metal free. We add the chemicals first to allow time for the chemicals to completely dissolve in the water, if any of the chemicals settle to the bottom of the pool we can use a pool brush to move them and get them to dissolve.
  2. Lower Water Level Below Skimmer
    By lowering the water level below the skimmer it makes it easier for us to blow out the skimmer lines and make sure that they are completely free from any water during the winter. If you have a vinyl pool liner and you live in in area with high water tables you should keep your water at normal operating level for the entire winter, this will help to ensure that your liner does not float.
  3. Remove Fittings From Return
    Remove all fittings from your return lines. Including directional flow fittings, quick release fittings for your pool vacuum, or anything else that was attached to your pool returns.  Remove baskets from the skimmer and from the pump. Remove The plug from your filter, if your filter is a DE filter after the water has drained replace the plug for the time that you will be blowing the lines.
  4. Blow Out The Lines
    Blow all of the water out of the skimmer, the main drain, and your returns. Keep the air blowing through your returns until you have them all plugged. This is important in case some of your returns are plumbed in line, start with the return that is closest to the pool pump and filter.  Make sure to open all of the lines in the pool to blow the air through your chlorinator hot water heater or any other things that are plumbed not in line with the rest of the pool.After you have blown all of your returns your skimmer while your main drain has air bubbles coming through it from your blower close the valve for the main drain to block water from returning back into the line. At this point there should have been blown through all of the pool.
  5. Remove Plugs
    Remove plugs from your filter, pump, chlorinator, and the heater if you have one. Any other equipment around the pool should be checked to see if there are plugs that should be removed for winterizing. If your pool has a heater check the owner manual for any other steps that need to be taken for winterizing.
  6. Cover Pool
    Now is the time to put on your safety cover.  All the steps leading up to this one have been only for your pool and its equipment, putting a safety cover is important during the winter, because the safety cover not only protects your pool, but also it is what keeps you, your family and your pets safe through the winter.  A good safety cover will keep your water clean and free from algae all winter long.  For more info on choosing the right safety cover see my blog

Every pool is different, and there could be some things that are not mentioned that should be done for your pool.  It is best to consult a pool professional especially if this is your first year owning a pool.
