How often should rainwater tanks be cleaned?
Routine water tank care is simple: clear gutters, leaf screens, and first-flush diverters every six months to stop debris from entering the tank. Inspect the internal base every two to three years; if you spot a layer of sludge, pump out and hose down the floor, then disinfect if the tank supplies drinking water. Sticking to this cycle keeps stored water fresh and preserves the long-term integrity of your poly water tank.
