Sediments often form in lifting stations which collect the wastewater from drain systems. Over time, the solids are compacted and reduce the available volume to the tank, often leading to the pump fouling.
A specific procedure involving lengthy, expensive system shutdown, is therefore necessary to remove them.
The flushing valve FLX is a hydraulic accessory that automatically generates an adjustable-direction jet of water inside the pit whenever the pump is restarted thus preventing sediment from collecting on the bottom of the tank.
