How should the pre-filter pad be cleaned?
The pre-filter pads are washable and can be back washed holding the pre-filter under tap water in inverted position. One can also remove the pre-filter pad; hold it under running tap water and squeeze it several times. This will increase the life of pre-filter pads. The frequency of back flushing depends on the quality of incoming water, however this should be done at least once every 15 days.
