It is important to maintain the system to ensure that the water quality is at its best at all times.
Roof Gutter, Rain Heads, Water Diverters and tank screens should be checked regularly. Check all rain head and tank screens and ensure that they are in good condition and are fitted to prevent mosquitoes entering the system. Drain First Flush Water Diverters and remove the main drain cap to dump any large rubbish, clean the flow control valve and screen.
Make sure that the overflow screen from the tanks are clear. Flap valves are cost effective and are better than most fixed screens because they are mostly self cleaning.
Make sure that the roof gutters are not ponding water especially at the corners and that the gutters are in good condition and not rusting.
Check inside the home/building to ensure that all taps are in good condition, replace tap washers if the tap is hard to turn off.
