Step 1. Drain and remove the old pump. Check the old pipe for scale, lime,
Tee and
rust, etc., and replace it if necessary.

Step 2. Install the pump in the system. Make sure that all pipe joints in the
suction pipe are air-tight as well as water tight. If the suction pipe
can suck air, the pump will not be able to pull water from the well.
Step 3. Adjust the pump mounting height so that the plumbing connections

do not put a strain on the pump body. Support the pipe so that the

pump body does not take the weight of piping or fittings.

Well Point (Driven Point) Installation (Figure 1)
Step 1. Drive the well, using "drive couplings" and a "drive cap". "Drive
fittings" are threaded all the way through and allow the pipe ends
to butt against each other so that the driving force of the maul is
carried by the pipe and not by the threads. The ordinary fittings
found in hardware stores are not threaded all the way through
the fitting and can collapse under impact. "Drive fittings" are
also smoother than standard plumbing fittings, making ground
penetration easier.
Step 2. Mount the pump as close to the well as possible.

Step 3. Use the fewest possible fittings (especially elbows) when connecting
the pipe from the well point to the pump suction port. The suction
pipe should be at least as large as the suction port on the pump
(include a check valve if your pump is not equipped with one – see
Figure 1). Support the pipe so that there are no dips or sags in the
pipe, so it doesn't strain the pump body, and so that it slopes slightly

upward from the well to the pump (high spots can cause air pockets

use on PVC. Joints must be air- and water-tight. If the suction pipe
can suck air, the pump cannot pull water from the well. If one well
point does not supply enough water, consider connecting two or
three well points to one suction pipe.

Cased Well Installation, 2
(Figure 2)
Step 1. Mount the pump as close to the well as possible.
Step 2. Assemble the foot valve, strainer, and well pipe (see Figure 2). Make
sure that the foot valve works freely.
Step 3. Lower the pipe into the well until the strainer is five feet above the
bottom of the well. It should also be at least 10 feet below the well's
water level while the pump is running in order to prevent the pump
from sucking air. Install a sanitary well seal.
