🍂 Autumn Tank Check: Is Your Water Storage Ready?

Get your water system prepped before winter! Here's a quick checklist to help you get started!

✅ Clean Your Gutters and Downpipes: Ensure that your gutters and downpipes are clear of leaves and debris to maximise rainwater catchment. This will help keep your water tank full and reduce the risk of blockages.

✅ Clean Your Tank: Autumn is the perfect time to clean your water tank to ensure your water supply is in top-notch condition before winter.

✅ Inspect and Repair Leaks: Regularly check your water tank and pipes for any leaks and fix them promptly. This will prevent water wastage and ensure your tank remains full.

✅ Install a First Flush Diverter: Consider installing a first flush diverter to prevent the first flush of contaminated rainwater from entering your tank. This will help maintain the quality of your stored water.

✅ Check Tank Filters and Screens: Clean or replace any filters and screens on your water tank to ensure they are functioning properly. This will help keep debris out of your tank and maintain water quality.

✅ Monitor Water Levels: Keep an eye on your water levels and use water-saving measures if necessary. This will help ensure you have enough water stored for the winter months ahead.

Not got a tank yet? Autumn is the perfect time to plan your water storage system before winter rains arrive!
