INTRODUCTION
Backwash pipe
A pipe is necessary to take the backwash water from the backwash manifold back to the water source
(comply with your local regulations) or to the closest drainage ditch.
In order not to limit backwash flow rate:
• The backwash pipe should be no longer than 20 m (65 ft).
• The pipe diameter should never be smaller than the backwash manifold diameter.
• If the backwash pipe length is 33 ft or less, it should be of the same diameter as the backwash manifold.
• If the backwash pipe is longer than 33 ft, its diameter should be larger than the backwash manifold.
• The pipe should not ascend above the elevation of the flushing manifold outlet.
Tools required for installation
• No special tools are needed. A standard full installer toolkit is adequate.
• To connect the control stand to the concrete slab, an electric hammering drill and a concrete drill bit.
• To connect grooved couplings, the following wrenches are required:
