Well Tanks & Pressure Switches in Southern NH
A.J. LeBlanc Heating's licensed New Hampshire plumbers replace well tanks and service pressure switches, gauges, and check valves. We diagnose short cycling and pressure swings before recommending a repair.
How Well Tanks & Pressure Controls Work
A well tank, also called a pressure tank, stores water under pressure so the well pump does not start every time a faucet opens. When the tank loses its air charge or the internal bladder fails, the pump may cycle rapidly and water pressure can rise and fall throughout the house. A.J. LeBlanc Heating checks the tank, pressure switch, gauge, check valve, and related controls to identify the part causing the problem.
When well pressure is inconsistent, the tank is only one possible cause. Our licensed plumbers test the pressure switch, gauge, check valve, related controls, and accessible piping, then explain whether the system needs an adjustment, a component repair, or a properly sized replacement tank.

Replacement, Diagnosis & Controls
Signs the Well Tank or Pressure Controls Need Service
Rapid cycling, changing pressure, water at the tank's air valve, visible corrosion, or a pressure switch that does not operate correctly can point to a problem with the equipment inside the home. We test the system instead of replacing a tank from the symptom alone. If the tank has failed, we size the replacement to the home's pressure settings and the existing system.
- Waterlogged tank diagnosis (bladder failure vs. air loss)
- Short-cycling diagnosis on the pressure side
- Pressure switch testing and replacement
- Pressure gauge and check valve service
- Accessible above-ground wiring inspection
Well Tank Replacement Done as a Complete System Repair
A well-tank replacement may also call for a new pressure switch, gauge, check valve, shutoff, or nearby piping. We explain which components are still serviceable and include the approved work in a written estimate. The new tank is installed, set to the correct pre-charge, and tested with the home's pressure controls before the job is complete.
- Amtrol Well-X-Trol, Flexcon, and Pentek bladder tanks
- Captive-air and older galvanized tank replacements
- Tank sized to the existing pump and household demand
- New pressure switch, gauge, and check valve when needed
- Pre-charge set to match your pressure switch (30/50, 40/60 PSI)
- Tested with the home's pressure controls before we finish

Well Tank & Pressure Switch FAQ
How do I know whether my well tank is failing?
Common signs include rapid pump cycling, pressure that rises and falls, water at the tank's air valve, visible corrosion, or a tank that has become waterlogged. We test the tank and controls because similar symptoms can have more than one cause.
What size well tank do I need?
Tank sizing depends on the existing system, household demand, and pressure-switch setting. We inspect those conditions and size the replacement for proper cycling rather than replacing it by physical dimensions alone.
What parts of the pressure system do you service?
We service the equipment inside the home, including the well tank, pressure switch, pressure gauge, check valve, related controls, and accessible above-ground wiring.
Why does my well pump turn on and off so quickly?
Rapid on-and-off operation is called short cycling. A waterlogged or failed tank, incorrect air charge, pressure-switch problem, or another control issue can cause it. We inspect the pressure-side equipment inside the home to find the cause.
