[ 44. A filtration system comprising:
a filtration chamber,
a filtration-element housed within the filtration chamber, wherein the filtration-element comprises a body of the filtration-element,
a common valve comprising a valve housing in fluid communication with the filtration chamber, with a source of fluid to be filtered, and with evacuation port for backflush fluid, through three respective openings in the valve housing, the three respective openings comprise an inlet opening an outlet opening and an evacuation opening, wherein the outlet opening is permanently open,
wherein the common valve comprises a plug that is movable within a central void of the common valve between a first position and a second position, wherein the first position is associated with a filtration mode of operation of the filtration system, wherein the second position is associated with a backflush mode of operation of the filtration system,
wherein the common valve, the filtration chamber, and a tube segment connecting therebetween, are mutually configured to provide for a linear flow-channel extending from the inlet opening of the common valve to the body of the filtration-element whenever the common valve is in the filtration mode of operation, wherein the linear flow-channel provides a sightline from an outer side of the inlet opening to the filtration-element. ]
