I'm installing the pump 404 to use in a basement bar. I have to zig zag through the bar up the wall (7 ft.) in the ceiling down to the drain; total distance before starting going down to the drain is 18 feet. In that distance I have five 90 degree angles to negotiate. Can I downsize from 1 1/2 inch to one inch along the way to make it easier?

Manufacturer's manual calls for a minimum of 1-1/2" pipe in order for the system to function properly and be covered under warranty.
