At Blue Science Fiberglass Pools, we understand that Texas winters can be unpredictable, with temperatures dropping significantly and then rising again. This can lead to challenges when it comes to protecting your fiberglass pool from the damaging effects of freezing temperatures. Fortunately, fiberglass pools are some of the best pool options for colder climates. Their durable, flexible construction helps them resist cracking and damage, even during the freeze-thaw cycles common in colder seasons. However, there are still important steps to take to ensure your pool remains in great shape throughout the winter months, especially in areas like San Antonio, Houston, Dallas, and Austin.
Believe it or not, fiberglass pools are among the best pool materials for cold climates. Their high-strength, flexible composition makes them less prone to cracking compared to other pool materials like concrete or vinyl, even in the face of freezing and thawing. The natural elasticity of fiberglass allows it to expand and contract with temperature changes without suffering significant damage. This is especially important for pool owners in Texas, where the weather can fluctuate between freezing temperatures and mild conditions within a short span of time.
Although fiberglass pools are built to withstand freezing temperatures, it’s still essential to take precautions during winter months to prevent any potential issues.
When Is Winterizing Necessary?
In Texas, winterizing your pool is not usually necessary unless there is an extended period of freezing weather. If you live in areas like San Antonio, Houston, Dallas, or Austin, where winter freezes are rare but still possible, you should monitor the weather closely. The only time you really need to winterize your pool equipment is during an extended hard freeze—when temperatures remain well below freezing for an extended period of time and the electricity goes out. During these conditions, the risk of damage to your pool equipment increases, which is why it’s critical to take proactive measures.
Key Steps to Protect Your Fiberglass Pool in Freezing Weather
If you’re concerned about freezing temperatures impacting your fiberglass pool, there are several steps you can take to keep your pool in top condition. At Blue Science Fiberglass Pools, we want to ensure you are prepared to protect your investment and keep your pool running smoothly throughout the winter.
1- Keep the Pool Equipment Running
If power is still available, the most important thing you can do is keep the water circulating. Continuous circulation helps prevent water from freezing inside the plumbing and equipment. Even if the pool surface starts to freeze, as long as the water keeps moving, the risk of damage is greatly reduced.
Remember that in colder temperatures, it’s crucial to keep the pump and filtration system running to avoid any water in the system freezing. Freezing water can cause pressure to build up in the equipment, which could potentially lead to cracks or ruptures. Keeping the water moving is the key to avoiding this.
2- Drain Plugs and Equipment Maintenance
If circulation stops or the electricity goes out, you’ll need to take steps to prevent damage to your pool equipment. For this, it’s essential to remove the drain plugs from the heater, pumps, filters, and any other equipment that contains a drain plug. These plugs are typically located at the front of the equipment, where the water pipes go in and out, and on the opposite side, at the back.
It’s vital to remove these plugs as quickly as possible to allow any remaining water to drain from the equipment. Failure to do so could result in cracked pipes or damaged components when the water freezes.
3- Protect the Skimmer
Another common issue during freezing weather is the pressure exerted on your pool’s skimmer. As water freezes, it expands, and this expansion can place significant pressure on your skimmer, causing it to crack or break.
To prevent this, we recommend placing an empty, sealed soda bottle inside your pool’s skimmer. To ensure it works effectively, fill the bottle about 1/3 of the way with water so it partially sinks into the skimmer. This prevents the ice from pushing the bottle out of the water and ensures it absorbs the pressure as the ice expands. This small precaution can save you from costly repairs down the road.
4- Turn Off the Pool Equipment
Once the weather warms up and the threat of freezing passes, it’s essential to turn off the power to your pool equipment. If the power comes back on too soon, it could cause the equipment to run dry, which could damage the pump and other components. This is a crucial step that many pool owners overlook, but it’s important for the long-term health of your pool.
Make sure to power down your pool equipment completely before you assume it’s safe to leave it running again.
5- Insulate Pipes and Exposed Faucets
Exposed pipes and faucets are particularly vulnerable to freezing temperatures. To protect them, consider wrapping the pipes and faucets in foam insulation or pipe insulation tape. This extra layer of protection helps prevent freezing and reduces the risk of pipe bursts.
It’s a simple yet effective solution that can save you from expensive repairs if a pipe were to freeze and break during the winter.
6- Invest in a Winter Pool Safety Cover
A winter pool cover is another great investment to protect your fiberglass pool in Texas during the colder months. A safety cover will help shield your pool from debris, prevent excessive water evaporation, and help maintain the temperature of the pool. While it’s not a necessity in every situation, a winter safety cover can offer extra protection, especially during periods of heavy frost.
7- Avoid Using a Space Heater Near Equipment
Never use a space heater near your pool equipment. While it might seem like a good idea to keep the equipment warm, it poses a significant fire risk and can damage sensitive components.
8- Never Drain the Pool
Avoid draining your pool, even during freezing conditions. Keeping the pool full helps maintain structural integrity and prevents the pool walls and floor from cracking under pressure due to temperature fluctuations.
