Backwashing

Whilst not directly affecting the water on it's journey to your home, this process is necessary to keep the filters in good working order.

When the filters have collected lots of dirt from the water they need a good clean once a day, before they are totally blocked. This is done by BACKWASHING, which is when clean water is pumped back through the filters the opposite way to flush out all the accumulated dirt and collect it in a special back wash tank.
