Pre-Installation
(Continued)
The pump stops when pressure reaches
a cut-out setting.
PACKAGE SYSTEMS
There are four jet pump/tank
assemblies sold as packages (Chart 1).
WELLS
A new well should be pumped clear of
sand before installing the pump. Sand
will damage the pumping parts and
seal. The drawdown level of the well
should not exceed the maximum rated
depth for the pump. The capacity of
the pump will be reduced and a loss of
prime may occur.
Installation
LOCATION
Select a location as close to the water
supply as possible. Be sure to comply
with any state or local codes regarding
the placement of the pump. The
equipment must be protected from the
elements. A basement or heated pump
house is a good location. Make sure
the pump has proper ventilation. The
temperature surrounding the pump is
not to exceed 100° F (40°C) or nuisance
tripping of the motor overload may
occur.
PIPING
Piping may be copper, steel, rigid PVC
plastic or flexible polyethylene plastic.
Flexible pipe is not
recommended on
suction pipe (inlet pipe).
The pipe must be clean and free of rust
or scale. Use a pipe joint compound on
the male threads of the metal pipe.
Teflon
®
tape should be used with
plastic threads. All connections must
be air tight to insure normal operation.
Slope all inlet piping upwards towards
the pump to prevent trapping air.
Unions or hose couplings can be
installed near pump to facilitate
removal for servicing or storage. A
rubber hose installed between the
water system and the house piping will
reduce the noise transmitted to the
house.
PIPE SIZES
Long horizontal pipe runs and an
abundance of fittings and couplers
decrease water pressure due to friction
loss. See Chart 2 to determine the
proper pipe size.
SHALLOW WELL INSTALLATION
A shallow well pump can be used when
the pump is located within 25 feet
vertically of the water level. Shallow
well pumps have only one pipe
between the pump and the water
supply (Figure 3).
DRILLED WELL (FIGURE 12)
1. Install a foot valve on the first section
of pipe (Figure 3, Illustration A).
2. Lower the pipe into the well.
3. Add pipe until the foot valve is 5
feet below the lowest anticipated
water level.
The foot valve
should be at least
18” from the bottom of the well or
sand or sediment could be drawn into
the system.
4. After proper depth is reached,
install a well seal or pitless adapter
to support pipe and prevent surface
water and other contaminants from
entering well.
5. Slope the horizontal pipe upward
toward the pump to eliminate
trapping air. Sloping the pipe will
also aid in priming the pump.
DRIVEN WELL (FIGURE 12)
1. Drive the point several feet below
the water table.
