Closing Your Swimming Pool

Close Your Pool


To the states that have a white Christmas, closing your pool is essential to keep your water and equipment to stay happy and healthy. Winterizing your swimming pool helps protect your pool from freeze damage that occurs from the expansion of ice within your pool equipment. It also helps keep your pool water clean and well balanced for the next season. Closing your swimming pool can save you a ton of time and work when it’s finally time to swim again.

In order to make your holiday season a little less chaotic, here are the seven steps to winterizing your swimming pool:

What You’ll Need:


Water Testing Kit
Winterizing Chemicals
Air Compression or Shop VAC
Winterizing Plugs
Skim Insure
Winter Cover
Water Tubes

Step 1: Water Balance

Without proper water chemistry, it is likely that staining will occur. Improper pH levels can also be destructive and corrode the pool and its equipment.


Step 2: Cleaning

Scrub the walls of any dirt or debris and ensure that your pool cleaner cleared the bottom. Dirt and debris that’s left in the water can cause staining.


Step 3: Winterizing Chemicals

These chemicals are going to keep your pool safe and clean during the winter months. Remember to circulate your pool’s water after you add the chemicals for at least 1-2 hours to ensure everything is distributed evenly.


Step 4: Remove Accessories

You’ll want to remove all the major accessories your pool has. This includes skimmer baskets, eyeball return fittings, cleaners, solar covers, and ladders.


Step 5: Winterizing Pool Lines

Next, you’ll have to winterize the plumbing lines within your pool’s system. Using a shop vacuum or an air compressor, you’ll blow air from the skimmer, through the equipment, and back into the pool. Air should now be coming out of the skimmer lines, return jet lines, and the suction lines. While this is happening, plug the returns using winterizing plugs. For the skimmer, use a Skim Insure plug to prevent your skimmer line from breaking due to water freezing.


Step 6: Removing Pool Equipment

Remove the drain plugs from the pump, filter, heater or heat pump, and chlorinator to allow the water to drain out. Make sure all water is drained from these to prevent freezing or cracking. To further product your pool heater, use a specialized heater winter cover.


Step 7: Winter Covers

Position your winter cover over your pool to where there are no gaps or holes for debris to enter through. In order to secure the cover, you’ll need to use water tubes or aqua blocks. These products will keep the cover in place during high winds. When using water tubes fill them 2/3 full. With aqua blocks only filled to the designated fill line.


Take that, winter! Now your pool will be ready and easy to open when spring comes around again. If you need any further instruction or have any questions, feel free to contact us.
