The following notes and recommendations refer to
Figure 26 (page 260), Figure 27
28 (page 262), and Figure 29
A. Distance between the clamps that secure the
drop cable to the delivery pipe.
B. Distance from the bottom of the well to the elec-
tric pump.
Recommendations:
• Non-return valve at 10 m distance from the deliv-
ery flange, plus an additional non-return valve
every 30-50 m of piping.
• Secure the drop cable to the pipe every 2 to 3
metres of piping.
• Make sure the electric pump is installed at a safe
distance from the bottom of the well.
