The Whole House Semi-Auto system is installed on mains plumbing, sediment and chlorine are removed from all taps and showers throughout the house, at up to 45 litres per minute, protecting your tap washers, hot water systems and appliances.
The backwash valve within these systems extends the life of the granular activated carbon media by enabling it to be back-washed and cleaned. All sediment and sludge is flushed to waste, either into the garden or storm water drain. This allows the mechanical clockwork operation to back-wash, stopping automatically at the end of the short cycle. Using this method the carbon media will last the average household three to four years, depending on water quality and usage.
