End of Swim Season Pool Closing Tips

End of Swim Season Pool Closing Tips

Can you believe we’re already halfway through October? After months of enjoying refreshing dips in our pools, it’s nearly time to prepare them for the chilly months of winter. But closing a pool means more than just throwing a cover over it and calling it a day. To protect your pool throughout the winter, there are a few other precautions you should take as well.

Mind Your Timing

Closing a pool when the weather is still warm can contribute to algae growth during the winter. Here in Maryland, where we’ve had some unseasonably warm fall days, it’s not quite time to close your pool just yet. To avoid problems like algae growth, wait to close your pool until the water stays at a steady temperature of 65°F or lower.

Treat the Water in Advance

This is a three step process. Start by balancing the chlorine, pH and alkalinity of your pool about a week prior to closing it. A few days later, shock the pool to eliminate any lingering bacteria growth. Once the chlorine levels return to normal, add a winter algaecide and let it circulate through the pool system for at least 24 hours before you close the pool.

Protect Your Plumbing

Before closing your pool, you should always blow the lines out from the skimmer to the pool to remove any excess water in the plumbing. If you don’t blow out the lines in advance, water can freeze during the winter and cause serious damage to your pool’s plumbing. Once you’ve cleared the lines, use expansion plugs to close them and prevent water from flowing back in.

Drain All Equipment

In addition to lowering the water level of the pool itself, you should also drain equipment such as pumps, filters, heaters and chlorinators to prevent freezing during the winter. If possible, store the pump and filter indoors once your pool is closed as well.
