2. Jet pumps can also be used with dug wells,
driven wells, or with cisterns or lakes.
Ventilation - Ventilation and drainage must be provided to prevent damage to the motor from heat
and moisture.
Freezing - Pump (A) and all piping must be protected from freezing. If freezing weather is forecast,
drain pump or remove completely from the system.
Water Supply - The water source must be able to supply enough water to satisfy the capacity of
pump (A) and water needs. See performance chart on page 2.
Suction Lift - Suction lift is the vertical distance from the lowest level of the water to the pump (A)
intake. Pump (A) will move water as long as it is within 25 vertical ft. of the water source.
Horizontal Distance - The horizontal distance is the horizontal measurement between pump (A)
suction and the water source. This distance may affect the ability of pump (A) to operate. If it is more
than 100 ft., call the manufacturer for assistance: 1-866-994-4148.
Pipe And Fittings
3. Use galvanized steel or NSF PW Schedule
40 PVC pipe and fittings. This material is
designed for water pressure and will seal
against air and water under pressure. Do
not use DWV fittings, as these are designed
for drains without pressure and will not seal
properly.
CAUTION: The entire system must be air
and water tight for efficient operation, and to
maintain prime.
Wire Size:
The wire size is determined by the distance from the power source to the pump motor and the
horsepower rating of the motor. See the wire chart in ELECTRICAL CONNECTIONS for proper wire
size.
