Please equip the intake line with a check valve so that the existence of the water column is rifled. Please fill the pump and the suction line with water before commissioning, there is a risk of dry running. The suction line should have a diameter of 1 inch - 1 1/4 inch, but not smaller or larger. Otherwise, the pump cannot provide the appropriate power or pressure. !! If you think that the pump does not suck water, please consult with a specialist and search for possible installation errors. !
