- The vertical lift is the elevation difference between the "off float" and the highest point in any zone.
- The diameter of the pipe from the pump tank to the hydraulic unit is 1-1/2" minimum.
- All supply and return pipes are 1".
- The flush return pipe from the hydraulic unit to the pretreatment tank is 1-1/2" gravity.
- The maximum distance from the pump tank to the hydraulic unit is 30'.
- The tables may be used with the standard zone detail configuration only. A calculation sheet must be filled out for any other configuration.
- Top feed manifolds must be used when any discernible slope is encountered.
