GUIDE BOX INTERNAL PIECE

The guide box internal piece is made up of five components:
The entrance pipe, pumping pipe and protector are made of PVC pipe. Diameter is determined by well depth.
The ceramic piece and the base part do not vary regardless of well depth.

Measurement variations for the guide box internal piece

Drawing No	Component		Depth (meters)
Drawing No	Component	Unit	0 - 11	11 - 19	19 - 50
2	Ceramic piece	-	-	-	-
3	Base diameter	Inches	2	2	2
1	Entrance pipe diameter	Inches	1 1/2	1	3/4
4	Pumping pipe diameter	Inches	1	3/4	1/2
-	Diam. of pumping pipe protector	Inches	1	3/4	1/2

PVC pipes may vary in diameter depending on the manufacturer. However, it is recommended that they correspond in diameter to the pistons' nominal diameter. This prevents water leaks and increases pumping efficiency.
The ceramic piece may be replaced by an electric insulator or a bottle, provided that the rope does not wear away.
