Protecting Your Swimming Pool During a Deep Freeze

A widespread winter storm advisory has been issued across the United States, with record-low temperatures and deep freeze conditions projected in what marks the first significant Arctic blast of the winter season, according to the National Weather Service.

Severe Weather Advisory Throughout The U.S.

This severe winter weather is expected to impact much of the country, with weather advisories, watches, or warnings in every state. The forecast includes wind chills dropping temperatures to below negative 40 degrees in parts of the northern Plains and northern Rockies. The Midwest and Great Lakes are anticipated to experience heavy snow and blizzard conditions, while the Southeast and East Coast will face heavy rain and coastal flooding. Some regions may also encounter severe thunderstorms, strong winds, and possible tornadoes.

Deep Freeze Conditions

Given the extremely low-temperature conditions, homeowners, especially pool owners, need to take proactive steps to protect their swimming pools from a possible deep freeze; should a loss of power occur.

Losing power during freezing temperatures poses significant risks to a swimming pool. When temperatures drop below freezing, the water in the pool can turn into ice, leading to a range of potential issues.

Protecting Your Pool From a Deep Freeze

The most immediate concern is the potential damage caused by the expansion of freezing water, which can lead to cracks in the pool structure, damage to plumbing, and harm to pool equipment. If the pool is not adequately protected, the consequences can be costly and time-consuming to repair.

To safeguard a swimming pool from freezing, it is crucial to take proactive measures such as covering the pool, using insulation, and employing backup power sources for heating systems. Addressing this issue promptly is vital for pool owners, as the damage resulting from frozen water can be extensive and may require extensive repairs, impacting both the functionality and aesthetics of the pool. By addressing the issue promptly and implementing preventive measures, pool owners can avoid potential damage and ensure the longevity of their investment in a well-maintained swimming pool.

To safeguard your pool equipment during freezing weather, consider the following tips:

1. Make sure the pool pump is running continuously when temperatures are below freezing. Install a freeze protection device that automatically turns the pump on when the temperature drops to around 34 degrees, maintaining pool operation in close-to-freezing conditions.
2. Keep the pool clean by regularly clearing skimmers and main drains of leaves and debris. A blocked system can prevent the pump from moving enough water to prevent freezing.
3. Maintain the proper water level to prevent skimmers from running dry and causing the pump to lose prime. In freezing conditions, low water levels can lead to frozen plumbing.
4. Remove the drain plug or open the hose bib on the backwash line to prevent water retention, freezing, and potential breakage.

Protecting Your Pool If You Lose Power

In the event of a power failure during a winter storm, your pool pump may cease operating unless you have a home generator as a backup. For an un-winterized pool, take immediate action by unscrewing the two drain plugs on your pump and heater, along with the single filter drain plug. Open the filter air bleeder and any closed pool line valves. Turn off the breaker to prevent the pump from starting without water. Once power is restored, replace the plugs, prime the pump, and restart it.

If, unfortunately, your pool equipment has already frozen solid due to a missed opportunity to take preventive measures, here’s a course of action. Firstly, shut off all power at the breaker. Cover the frozen equipment with heavy woolen blankets, creating a makeshift ‘tent.’ Safely position a small space heater inside the tent and monitor closely until thawed, inspecting for potential cracks. If repairs are necessary, drain the equipment until it can be properly fixed.

As this current winter storm unfolds, it is crucial for homeowners, especially pool owners, to be proactive and take these steps to ensure the safety and functionality of their pool equipment in the face of extreme weather conditions.
