All sand filters require periodic backwash to remove debris from the filter sand and keep filter back pressure not too high in order to maintain good water circulation.
When the filter multiport valve (MPV) handle is turned to backwash, this sends the water in the reverse direction through the filter and then to waste. During the backwash cycle, watch the sight glass and continue the backwash until the water flowing to the drain runs clear then turn off the pump.
It is recommended that sand filters should be backwashed according to the following timetable or whenever the filter pressure is high.
It is important that every time you turn the handle of the filter, you must stop the pump first.
