Inquiry (采购产品): Suction & Discharge Hoses I have a Pacer pump Model # SE2UL E5HOC Code #78980 fitted with a Honda 5.0 hp gas motor. I use the system to fill my pool from a pond. I tried to prefilter the water from the pond through an old Diatomaceous Earth pool filter hooked after the pump, but I encountered too high flow pressures using the 2" suction lines. Can I use smaller suction and outlet lines to reduce the pressure to the filter? How small can I go? Can I run the pump engine slower than full running speed to keep the pressure down? I would really appreciate any suggestions or help with keeping the pressure down so that I can prefilter the water which caused me a lot of problems last year. Thanks. **** Hidden Message ***** Andrew La Patra 330 Stage Rd Charlton, NY 12019 USA Company: AAI, Inc.
