How to Close Your Above Ground Pool for Winter


How to Close Your Above Ground Pool for Winter


Winter is coming! Is your above ground pool ready for the freezing weather? Read our simple step-by-step guide on winterizing your above ground pool to get things ready for Jack Frost.

Step 1: Clean the pool

As winter approaches, the first step to winterizing your above ground pool is to clean it. Brush down the walls, skim the surface, and vacuum the entire pool. This might not seem an essential task, but if your pool sits dirty during winter you leave it ripe for algae or mold development—you will not like what you find in spring. 

Step 2: Get the chemicals right

This is a crucial step in winterizing your above ground pool. It involves adjusting the pH level, calcium hardness, and alkalinity. By balancing the chemicals, you will be able to keep your pool clean and free from bacteria throughout the winter period.

The pH should be 7.2-7.6, Calcium hardness 175-250ppm, alkalinity 80-120ppm, and Chlorine 1-3ppm. Getting the optimum chemical levels prevents corrosion.

Step 3: Do a thorough inspection

Before you do a complete close-down, you need to do a thorough inspection of the pool area. There are so many things that can go wrong when your pool freezes. If it leaks, the leak will become much more prominent when the water expands.

If you find any rusty bits, brush them down with a wire brush to get rid of the rust. Once you get all the rust off, ensure you paint the exposed surfaces with anti-rust paint. Don’t forget to tighten any loose joints and screws.

Step 4: Winterizing Kit

You will need specific chemicals – winterizing compounds—to keep your pool safe during this time. Most winterizing kits come bundled with all the chemicals that you will need to apply to the water before you shut it down.

If you are a more of a hands-on pool owner, you can buy each chemical separately, then add them to the pool. This task is going to be more tedious, but it will save you money. On top of it, you will be able to customize the percentages depending on your pool.

Step 6: Lower the water level

One of the common mistakes that people make during winter is to drain out their above ground pools completely. That’s a recipe for disaster. Doing so damages the pool and is often the cause of hydrostatic pressure. Altogether remove water from the drainage valve using an air compressor.

Once all the water is out of the plumbing, add pool anti-freeze to the pipe. You can also add winter plugs with threading to prevent water from getting back in. Only use pool anti-freeze with your pool.

Step 7: Cover Your Pool

Lastly, use a winter pool cover to protect the pool. Make sure it is securely held down with a durable cable. If you live in a windy area, use a winter cover seal to prevent the pool cover from being blown away by the wind.
