Regularly inspect the inlet strainer to clear debris and clean the screen. If a wet system is used, ensure a drain is fitted at a low point. If a water diverter is fitted, the screen should be cleaned every three months. Check the tank pad for any erosion or undermining. Immediately rectify if this has occurred. Your tank may need to be cleaned internally every 5-10 years depending on its location. This will help keep your tank water clean and healthy.
Remember: Water quality is only as good as the catchment area!
