The maximum suction lift including pipe friction is 25ft (7.6m) at sea level. This figure is reduced by 1ft (0.3m) for every 100ft (305m) increase in altitude.

Delivery Pipe

Minimum pipe bore is ¾" BSP, or 22mm. If the length exceeds 150ft (45m) it may advisable to increase the size. The pipe should be as straight as possible, use long sweep bends for changes in direction. The delivery outlet must be arranged for open discharge.


Automatic Electric Installation

The water level is maintained by the action of the float switch, which switches the pump motor on if the tank is emptied and off when the tank is full.
