After some time, the flow rate may reduce because of clogging of the filter element. In this case, the filter can be cleaned by backwashing. This is done by closing the valve and squeezing the rubber bulb, which forces the water back through the filter element, pushing dirt particles out and unclogging the filter. This backwash option increases the lifetime of the filter element.
====Estimated Lifespan预估使用寿命====The filter element could produce up to 7.000 litres (enough for a large family for 1 year) of water before replacement在替换之前,过滤元件可以用于7.000公升以上的水(足够一个大家庭使用1年),塑料部件可以维持5年以上。The plastic parts last up to 5 years.

Figures are assuming filter replacement takes place every year but plastic parts last up to 5 years.
