Well Check Valve Replacement
Replacement of leaking check valves that let water drain back and cause the pump to restart.
A check valve keeps water moving in one direction, from the well into the house. When it leaks, water drains back down the pipe, pressure falls, and the pump starts again even when nobody is using water.
Well check valve replacement stops that backflow, protects the pump from extra starts, and helps the system hold pressure between uses.
Signs of a Leaking Check Valve
- The pump turns on briefly when no water is in use
- Pressure slowly drops overnight
- A banging sound in the pipes when the pump stops
- Air in the lines after the system sits idle
- Longer than normal run times after periods of no use
Locating and Replacing Check Valves
Check valves can be located at the pump, along the drop pipe, or near the pressure tank. We test pressure hold time to confirm a valve is leaking and identify which valve is the likely cause.
Valves at the surface can be replaced without pulling the pump. When the leaking valve is down in the well, we plan the pull carefully and inspect the pump and pipe while they are out.
Our Well Check Valve Replacement Process
- Step 1
Pressure hold test
The system is isolated to see whether pressure drops when no water is used.

Locate the valve
We identify which check valve is leaking based on the system layout.
- Step 3
Replace
The faulty valve is replaced with a properly rated new valve.
- Step 4
Confirm
Pressure hold is tested again to make sure the leak has stopped.
