Quick Answer
Before winter, inspect and clean your cistern, ensuring the water level is below the overflow to prevent back-siphoning. Check the drain valve for proper function and ensure it's not clogged. Consider installing a float valve to regulate water levels.
Preparing for Winter Drainage
If your cistern is buried in concrete, it’s essential to clear the area around the drain valve to prevent debris from accumulating and clogging the drain. For cisterns with a buried concrete slab, consider installing a drain line with a 1-2% slope to ensure water flows freely. This helps prevent water from accumulating and reduces the risk of ice formation.
Cistern Drainage Techniques
To ensure proper drainage, inspect the cistern’s drain valve and overflow assembly. Use a garden hose to flush the drain line, checking for any blockages or kinks. For cisterns with a buried concrete slab, consider installing a winterization kit that includes a drain valve with a frost-proof design. This helps prevent back-siphoning and ensures the cistern remains intact during freezing temperatures.
Maintaining Your Cistern Before Winter
Before the first frost, inspect your cistern for any signs of damage or wear. Check the concrete slab for cracks or erosion, and repair any damage to prevent water from seeping into the cistern. Also, ensure the cistern’s roof is secure and free of debris, as loose materials can clog the drain or cause water to accumulate. Regular maintenance helps prevent costly repairs and ensures your cistern remains functional throughout the winter months.
