The technology used to pump well water to a residence is so dependable that it rarely needs repair. If a repair is ever required, most of the system components are located above ground and are easily accessible. However, the components contained within the well itself are more difficult to reach. Homeowners who suspect that their submersible pump has failed may actually only need to repair a pipe rupture within the well casing.
A sudden loss of water always demands immediate attention. Your first response is likely to be to check the power supply, the pressure switch, and the water tank. If a problem is not found with an aboveground component, the failure could lie underground. Opening up a drilled well is a challenging endeavor and usually requires professional assistance.
Opening the wellhead
The submersible pump inside a drilled well is attached to the end of a lengthy pipe. The pump hangs from the end of the pipe and is typically suspended near the bottom of the well. Alongside the pipe is an electrical cable running from the wellhead to the pump. The weight of the well piping is made even heavier by any water held in the pipe.
You may have a perfectly good well pump, and the lack of water pressure may be due to a small hole somewhere in the pipe. The pump can be tested if it is removed from the well. Before attempting to remove the pump, there is a simple procedure to diagnose a rupture in the portion of the pipe above the water table.
Telltale signs of a rupture
The typical drilled well essentially contains a very tall column of water. The top of the water column is roughly in alignment with the water table. When electrical power is supplied to the pump, listen for the faint sound of falling water inside the well casing. The sound of falling water could be that of water exiting the rupture and falling back onto the top of the water column.
The rupture of a pipe above the water table is, relatively speaking, good news. The repair is much simpler than diagnosing a deeper rupture or replacing the pump. As the pipe is pulled upward from the well, the rupture will become apparent at the point where the piping is no longer dry.
Piping near the top of a drilled well is under greater stress due to the weight of the lengthy pipe. Nevertheless, a leak could potentially occur closer to the pump and require further visual inspection. As more pipe is pulled out of the well, the water held in the remaining piping weighs less.
