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 13)
1. Install a foot valve on the first section
of pipe (Figure 3, Illustration A).
2. Lower the pipe into the well.

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.

Valve
NOTE: A packer type foot valve can
be installed in the well (Figure 3,
Illustration B). This type of foot valve
allows the well to be fi lled with water
when priming and makes the inlet pipe
much easier to test for leaks. Follow
the manufacturer's instructions when
installing the packer type foot valve.
As an alternative, an in-line check valve
can be used with a driven well (Figure
3, Illustration C). The pipe between
the check valve and the water level will
always be under a vacuum.
Leaking joints or couplings will allow
air to leak into the pipe and cause
abnormal pump operation. Make sure
to use pipe joint compound on all male
Drive
pipe threads.

sediment could be drawn into the system.
NOTE: When a lake is used as a water
supply, make sure the inlet pipe is deep
enough to be submerged at all times.
Slope the horizontal piping upward
toward the pump to prevent trapping air.
The pipe must be removed during winter
months or protected against freezing.

1. Install air volume control on tank.
2. Connect the copper tube from the air
volume control to the uppermost 1/8"
NPT opening on the side of pump. Be
sure the connections are tight. Leaking
can cause the pump not to prime.
3. Install a valve and an isolator hose
between the tank and the house plumbing
to aid in pump removal for servicing and
for reducing the noise transmitted to the
house thrugh the piping.
4. Provide a hose bib (faucet) at the
lowest point in the system to drain
the system for service or storage.
