The Importance of Winter Pool Maintenance
During winter, your pool may go unused for several months, increasing the risk of frozen pipes, damaged filters and heaters, and algae growth. Proper maintenance throughout the winter can help prevent these costly issues from arising in the spring.
Fortunately, with a few basic precautions and winterization steps, you can keep your pool clean and ready for use when the warmer weather returns.
Tips for Pool Maintenance During Winter
Here are some tips for maintaining your pool during the winter:
- Treat the water with an algaecide. It’s generally recommended that you use algaecide about halfway through the winter season.
- Use a pool cover the entire time your pool isn’t used.
- Clean the pool regularly, even if it has a cover on it.
- Remove accessories from the pool and store them so they are clean and dry.
- Drain the filter, heater, and pump. This is essential because water can expand when temperatures drop below 32 degrees Fahrenheit and potentially crack or damage pipes.
- Do not drain the entire pool and leave it empty. Evaporation doesn’t happen in the colder months, so high pool levels can result in water freezing and cracked pool tiles. A preventive step is to lower the water level in your pool by two to six inches below the skimmer.
In addition to these one-off tasks, it’s also important to monitor the water chemistry to prevent freezing and deter bacteria or algae growth. You can use test strips to check your water’s alkalinity, pH, and chlorine levels, then add the proper chemicals to bring it back into balance. Aim to check your pool’s water chemistry every month.
Winterizing Your Pool Heating
Swimming pool winter maintenance isn’t just about the pool itself. You’ll also need to protect your entire pool system by taking the following winterizing steps:
- Drain the pool occasionally and partially fill it back up to the skimmer line
- Turn off the pool heating system
- Drain solar thermal panels and close the valves, preventing water from going into panels when the pool pump turns on
Re-Opening Your Pool At The End of Winter
You don’t have to wait for hot summer days to re-open your pool. Opening your pool early gives bacteria and algae less time to grow.
Be proactive with maintenance and make re-opening your pool a priority as soon as the weather improves. As a bonus, you get to enjoy a longer swimming season.
