Pressure Tank Service for Residential Wells
Your pressure tank is the shock absorber of the well system. It holds a cushion of air so the pump is not starting every time someone rinses a cup. When the bladder fails or the pre-charge is wrong, the pump short-cycles, noise increases, and motors burn out years early.
Roanoke Well Pump Repair inspects, recharges, and replaces residential well pressure tanks across the Roanoke region. Call (540) 384-5816 or email info@roanokewellpumprepair.com.
Signs Your Pressure Tank Needs Service
- Pump turns on every 30–90 seconds while water runs
- Gauge needle swings wildly instead of moving smoothly
- Water spurts or sputters at fixtures
- Tank feels completely water-heavy when you try the air-valve test
- New pump was installed recently and is already short-cycling
What Tank Service Includes
Pre-charge check
With the system depressurized, air-side pressure should sit about 2 psi below the pump cut-in setting. We verify and adjust when the bladder is still healthy.
Bladder evaluation
If water comes out of the air valve, the bladder has failed. Adjustment will not fix it; the tank needs replacement.
Right-size replacement
Tanks are matched to pump flow and household use so drawdown is comfortable and cycles stay reasonable.
Switch coordination
Tank work pairs naturally with pressure switch repair so cut-in and cut-out settings match the new setup.
Why Tank Neglect Destroys Pumps
Each unnecessary start dumps heat into the motor windings. A pump that should cycle a few times an hour may cycle hundreds of times a day on a dead tank. Replacing the tank is almost always cheaper than replacing the pump it was quietly killing.
Where We Service Tanks
Basements, garages, and pump houses in Roanoke, Salem, Lynchburg, Bedford, Christiansburg, and Blacksburg.
Pressure Tank FAQ
How long do bladder tanks last?
Often 5–15 years depending on quality, water chemistry, and whether pre-charge was maintained. There is no calendar that beats an on-site check.
Can I add air with a tire compressor myself?
You can check pressure after draining the system, but incorrect procedure risks waterlogging or inaccurate readings. If you are unsure, schedule service.
Will a bigger tank always help?
Up to a point. Oversized tanks on tiny pumps can feel sluggish; undersized tanks short-cycle. Matching matters more than maximizing gallons.
