What Is Swimming Pool Antifreeze?

Essentially, pool antifreeze is a solvent that is fluid, which is used to stop water inside the plumbing of the pool, from freezing. It also prevents expansion, which could damage the pipes during winter.

With the help of pool antifreeze, you’ll be able to protect the pipes of your fibreglass pool from low temperatures. This is a crucial part of maintaining your pool over the winter.

In a majority of the cases, you don’t need to use pool antifreeze. You can instead just blow the pipes clear of any water that might be inside. Antifreeze can be seen as extra protection, for those who aren’t sure about how clean their pool pipes are.

What Are The Ingredients Of Swimming Pool Antifreeze?

Where Should You Put The Antifreeze?

You’ll be pouring the antifreeze into the pool pipe that is connected to the pool’s skimmer basket.

How Much Antifreeze Is Needed?

If your swimming pool pipes are full of water, then use about a gallon of antifreeze. This should end up covering around 10 feet of a pipeline that is 1.5 inches.

Removing The Skimmer Basket And Plug

You will need to remove the skimmer basket as well as the plug. This way, you can reveal the pipe that you’ll be putting the antifreeze into.

Lowering Water Till It's Beneath The Skimmer

The water level of your fibreglass pool should be below the basket line of the skimmer before you add any antifreeze. This will help prevent water from reaching the pipe that has been treated.

(We compare three of the main pool filters; take a look!)

Pouring Antifreeze Into The Skimmer And Return Lines

Once the water in your pool has reached the correct level, add antifreeze which has been diluted, to the skimmer. This will help in protecting the skimmer line.

You can also think about adding extra protection to the cleaner line, the main pipeline, or the return line. The best technique in order to do this would be by connecting a hose to a valve or a pump. Then, pour the antifreeze in carefully using a funnel.
