      If oil is being sucked into the intake section of your MANN+HUMMEL Water Filtration System, there are several potential causes. First, check the mounting height. It might be too low. Second, verify that a non-return valve is installed in the oil return line. If not, install one. Finally, the separator element may be exhausted, requiring maintenance.
