The Best Time to Service Your Pool Isn’t Summer. It’s the Week After Heavy Rain.

 

Sydney has experienced one of its coldest stretches of winter in recent weeks, with heavy rain, low temperatures and plenty of windy days. While many pool owners stop thinking about their pool during winter, this is often when small issues begin to develop. A pool may look clean on the surface, but heavy rain can dilute your pool’s water chemistry, fill skimmer baskets with leaves and debris, and place extra strain on your filtration system. Left unchecked, these small issues can become costly repairs by the time spring arrives. If you own a pool on the Northern Beaches, North Shore or in Sydney’s Eastern Suburbs, now is one of the best times of the year to give your pool a quick health check.

 

What should you check after heavy rain?
  • A few simple checks can help keep your pool healthy throughout winter.
  • Check the water level. Heavy rain can raise the water level and affect how your skimmer operates.
  • Empty the skimmer basket. Leaves, twigs and debris quickly build up after wet and windy weather, reducing water flow.
  • Check the pump basket. A blocked pump basket forces your equipment to work harder and can shorten the life of your pump.
  • Remove leaves from the pool. Organic matter sitting in the water breaks down and affects water quality.
  • Test your chlorine and pH levels. Rainwater changes your pool’s chemistry, making it easier for algae and bacteria to develop.
  • Make sure your timer is running correctly. Even during winter, your pool still needs regular circulation and filtration to stay healthy.

These checks only take a few minutes, but they can prevent much larger problems later.

 

Winter is the best time to stay ahead

One of the biggest misconceptions is that pools can be ignored during winter because nobody is swimming. Your pool still needs filtration. Your equipment still runs every day. Your water still needs to stay balanced. Winter is also the perfect time to identify worn equipment, dirty filters, leaking pumps or ageing components before they fail during spring or summer when your pool is back in regular use. A little maintenance now is far less expensive than recovering a green pool or replacing damaged equipment later.
