What Does a Well Expansion Tank Do?
A well expansion tank stores pressurized water and prevents your well pump from turning on every time you open a tap.
Without a properly working expansion tank, your pump will short-cycle, electrical components will fail,
and water pressure will fluctuate throughout the home.
A properly installed expansion tank:
- Protects your well pump
- Maintains steady water pressure
- Reduces energy consumption
- Extends the lifespan of your well system
Signs You Need Expansion Tank Service
- Well pump turning on and off rapidly
- Water pressure jumping high then dropping
- Banging or water hammer noises
- Waterlogged or rusted tank
- Pump running when no water is being used
- Repeated pressure switch or pump failures
Ignoring these warning signs often leads to complete pump burnout and expensive emergency repairs.
Proper Expansion Tank Sizing Matters
Installing the wrong size expansion tank is one of the most common causes of short cycling.
Proper sizing depends on:
- Pump horsepower
- Gallons per minute (GPM)
- Household water demand
- Pressure switch settings
We calculate and install the correct tank size — not what’s convenient or cheapest.
Expansion Tank Repair vs Replacement
Some issues can be corrected by adjusting air charge. Others require full replacement.
We test:
- Air pressure
- Bladder integrity
- Corrosion and fittings
- Pump cycling behavior
If replacement is needed, we explain why and show you the data — no upselling.
