Well Point (Driven Point) Installation (Figure 1)
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. |
2. | Mount the pump as close to the well as possible. |
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 which can |
air lock the pump). Seal the suction pipe joints with PTFE pipe thread |
sealant tape. Joints must be air- and |
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. |

1.Mount the pump as close to the well as possible.
2.Assemble the foot valve, strainer, and well pipe (see Figure 2). Make sure that the foot valve works freely.
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.
4.Install a priming tee, priming plug, and suction pipe to the pump (see Figure 2). Connect the pipe from the well to the pump suction port, using the fewest possible fittings – especially elbows – as fittings increase friction in the pipe (however, include a foot valve – see Figure 2). The suction pipe should be at least as large as the suction port on the pump. 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 which can air lock the pump).
