Is there a way to hook the intake (suction line) to a source that is under pressure? I want to pump water but I would like to hood it to a pressurized water pipe. I know it will **** out of a tank but since I want to pump water, I don't want to have to fill the tank regularly.

The LMI ROYTRONIC A Series pump is designed for flooded suction installation or suction lift when the lift is less than 5 feet (1.5 m) for low-viscosity fluids. The manual does not mention direct connection to a pressurized water pipe for intake. Suction conditions can affect pump performance, especially for lower pressure pumps. For specific cases, consulting a distributor is recommended.
