Inspect your tank every few months. Walk around it and check for cracks, leaks, or fading, especially near outlets or base fittings. Make sure the foundation is still level and free from erosion. Early detection prevents minor issues from turning into expensive repairs later.
Most contamination starts before the water even reaches your tank. Clean gutters, downpipes, and leaf guards regularly—especially after storms. Install a first-flush diverter or filter system to stop dust, debris, and bird droppings from entering your water supply. A clean inflow guarantees cleaner water and less sediment inside your tank.
Over time, sediment and algae can accumulate inside your tank. Once every year or so, drain it partially and gently rinse out the base. Avoid using harsh chemicals; clean water or a mild vinegar solution works well. If your tank is large or underground, consider hiring a professional cleaning service to do a deep clean safely.
If your tank uses a pump, check its pressure, hoses, and seals to ensure consistent flow. Clean or replace filters regularly to avoid clogs that can affect water quality and pressure. A well-maintained pump system extends the life of your entire setup.
Sunlight encourages algae growth. Keep your tank shaded and sealed tightly to limit exposure. The olive-green, opaque tanks from Just Tanks are perfect for blocking light and maintaining freshness. If you ever notice mild odours, flush a small amount of stored water and let the system refill with fresh rainwater.
Every few years, book a professional inspection. Technicians can check structural integrity, replace worn seals, and test fittings. This not only ensures top performance but also keeps your 10-year warranty valid.
