When temperatures begin to drop, one of the most crucial steps in closing a pool for winter is protecting it from freezing damage. Many pool owners focus on covers and chemicals but overlook one essential safeguard, pool antifreeze. Without it, even a well-covered pool can suffer cracked pipes, damaged pumps, and costly repairs come spring.
At Anomaly Pool Services, we regularly see the damage caused by skipping or misusing antifreeze during winterization. This guide explains what pool antifreeze is, why it matters, how to use it correctly, and whether professional help is the smarter choice.
Pool antifreeze is a specially formulated, non toxic antifreeze designed specifically for swimming pool plumbing. Unlike automotive antifreeze, it is safe for pool systems and used only in plumbing lines, not mixed into the pool water itself.
The purpose of antifreeze for swimming pools is simple:
Frozen water expands, and that expansion can crack pipes, damage fittings, and destroy equipment. Once this happens, repairs can be expensive and time-consuming.
Using antifreeze for pool closing adds an extra layer of protection after the plumbing lines are blown out, especially in areas with harsh or unpredictable winters.
Even after draining and blowing out lines, small amounts of water can remain in low spots. That’s where pool antifreeze becomes essential.
Proper use helps with:
At Anomaly Pool Services, we include antifreeze as part of a complete winterization strategy, not as a shortcut, but as added insurance.
A very common question we hear is:
“Is pool antifreeze safe to swim in?”
Here’s the clear answer:
Pool antifreeze is added only to plumbing lines, not to the pool itself. Any trace amounts that eventually mix with water during spring opening are diluted and safe when handled properly.
Understanding where to add pool antifreeze is just as important as using the correct product.
Antifreeze is typically added to:
It is not added directly into the pool basin. Proper placement ensures water left in the lines cannot freeze and expand.
This step is often missed during DIY winterization, which is why professional services make a big difference.
Another common concern is:
“How much pool antifreeze do I need?”
The answer depends on:
On average:
Guessing can lead to under-protection or wasted product. Anomaly Pool Services calculates exact amounts to ensure full coverage without excess.
Inground pools usually have:
This makes antifreeze for inground pools especially important. These pipes are more vulnerable to freezing due to soil temperature shifts.
Many people ask:
“Do above ground pools freeze in the winter?”
Yes, they can, especially the plumbing and equipment.
Antifreeze for above ground pool systems is often used in:
While above ground pools are easier to drain, antifreeze still adds crucial protection.
Your pump is one of the most expensive components of your pool system. Swimming pool pump freeze protection involves more than just turning it off.
Key steps include:
Pool pump freeze protection is essential to avoid cracked housings and seized motors.
If you’re wondering how to keep pool from freezing in winter, the answer is a combination of steps:
Skipping even one step increases the risk of freeze damage.
Proper preparation is key to avoiding problems in spring. Knowing how to prepare swimming pool for winter includes:
Antifreeze plays a supporting role but is a vital part of complete swimming pool freeze protection.
Some homeowners choose DIY winterization, but mistakes are common.
