Well Pressure Tank & Switch Repair in the Flathead Valley
Your pressure tank stores water under pressure so the pump doesn't have to start every time you open a tap. When the tank or pressure switch fails, you get pressure swings, a pump that short-cycles, and eventually a burned-out pump. Fixing the tank early protects the much more expensive pump.
Signs of a pressure tank or switch problem
- The pump clicks on and off every few seconds while water runs (short-cycling)
- Pressure surges and drops in the shower
- The pressure gauge swings quickly or doesn't move
- Water sprays from the tank's air valve when pressed (failed bladder)
- The tank is sweating, rusting or leaking
- No water, with a pressure switch that's burned, pitted or frozen
Typical fixes
- Recharging the tank's air pressure
- Replacing a waterlogged or failed bladder tank
- Replacing or adjusting the pressure switch
- Replacing the pressure gauge, tank tee and fittings
- Adding a larger tank or a constant-pressure system for steadier pressure
Short-cycling is hard on the pump motor. If your pump is clicking on and off rapidly, get it checked soon — it's much cheaper to replace a tank than a pump.
Costs
A pressure switch is often a few hundred dollars installed; a new pressure tank is commonly in the high hundreds to around $2,000 depending on size. See our Flathead well cost guide.
