Well Pump Repair, Well Tank Replacement, and Well Water Service
Full Nelson services well water systems including submersible well pumps, jet pumps, pressure tanks, pressure switches, and related components. Our plumbers diagnose well system problems and restore reliable water pressure and flow.
How Well Water Systems Work
A well water system draws water from an underground aquifer through a drilled well. The well pump, located either at the bottom of the well (submersible) or at the surface (jet pump), pushes water into a pressure tank inside the home. The pressure tank stores water under air pressure and delivers it to your fixtures on demand without the pump running every time you open a faucet.
The pressure switch monitors tank pressure and tells the pump when to turn on and off. A typical residential system cycles between a cut-in pressure (usually 30 or 40 PSI) and a cut-out pressure (usually 50 or 60 PSI). When you use water, tank pressure drops. When it reaches the cut-in point, the switch activates the pump to refill the tank.
Well Pump Repair and Replacement
Well pumps are workhorses that run thousands of cycles per year. They eventually wear out, lose efficiency, or fail entirely. Symptoms of well pump problems include:
- No water at any fixture in the house
- Low water pressure that has gradually worsened over time
- The pump runs continuously without shutting off
- The pump cycles on and off rapidly (short cycling)
- Sputtering or air bursts from faucets
- A noticeable increase in electricity usage
Submersible well pumps sit hundreds of feet down inside the well casing. Replacing one requires pulling the pump and drop pipe to the surface, which is a labor-intensive process that requires specialized equipment. Full Nelson handles submersible pump replacement and installs pumps rated for the well depth and household demand.
Jet pumps are surface-mounted and more accessible for repair. Common jet pump problems include worn impellers, failed pressure switches, and air leaks in the suction line.
Pressure Tank Service and Replacement
The pressure tank is the component most responsible for consistent water pressure in your home. Inside the tank, a rubber bladder or diaphragm separates the water from a pre-charged air cushion. This air cushion compresses and expands as water enters and leaves the tank, maintaining steady pressure.
Signs of a failing pressure tank include:
- The pump short cycles, turning on and off every few seconds when water is running
- Water pressure fluctuates noticeably during use
- The tank feels completely heavy (waterlogged) with no air cushion remaining
- Visible corrosion, rust, or moisture on the tank exterior
A waterlogged tank has lost its air charge, usually because the internal bladder has ruptured. The pump runs almost continuously because there is no air cushion to maintain pressure between cycles. This dramatically shortens pump life. Full Nelson replaces pressure tanks and pre-charges them to the correct pressure for your system’s cut-in setting.
Pressure Switch and Control Components
The pressure switch is a small but critical component that tells the pump when to run. A faulty pressure switch can cause the pump to run nonstop, refuse to start, or cycle erratically. Full Nelson replaces pressure switches, check valves, pressure gauges, and other well system controls.
We also inspect and replace the pitless adapter, which is the fitting where the well pipe exits the well casing below the frost line and connects to the supply line running to the house. A failed pitless adapter causes leaks underground that reduce water pressure and waste water.
