❑ The suction line should be laid either exactly horizontal, or with a uniform slope
upward from the water supply to the pump. Avoid high spots or "air traps." Air
which collects at the high spots may be carried into the pump, causing
loss of prime, and must be scavenged with the priming pump.
❑ To avoid excessive friction loss, the discharge pipe must be sized accord-
ingly. The quantity of liquid being pumped, the length of line, the number
of elbows and fittings should be considered carefully in selecting the
proper size pipe.
❑ By using a friction table, all fittings can be converted to the equivalent of
straight pipe and the overall friction loss easily established. Also see
heading “Appendix D: Hose Friction Loss” on page 63.
❑ Be sure all connections in the suction line have matching threads and
gaskets and are used with the appropriate fittings. Suction connections
must be air tight at all times.
❑ If suction hose is used, check the hose rubber washers frequently, as for-
eign matter under these washers will cause air leaks.
❑ In special cases where the pump is used for pumping salt water, or when
you are forced to pump water containing sand or other foreign matter
always connect the pump to a “fresh water” source and pump the system
for a few minutes to clean-out all unacceptable residue.
