Well Pressure Tanks & Constant Pressure Pumps in Southern NH

Common signs include the well pump cycling on and off rapidly (short-cycling), low or fluctuating water pressure, water at the air valve on top of the tank, rust streaks on the outside, or a tank that feels heavy and waterlogged when tapped. Any of these usually means the bladder has failed or the pre-charge pressure is wrong.

A quality bladder tank like an Amtrol Well-X-Trol or Flexcon typically lasts 10 to 15 years in Southern NH, depending on water chemistry, pre-charge maintenance, and pump cycling. Older galvanized air-over-water tanks usually need replacement sooner.

The right tank size depends on your well pump's GPM rating, household demand, and the pressure switch setting (typically 30/50 or 40/60 PSI). A.J. LeBlanc Heating sizes each replacement so the pump runs full cycles, which extends pump life and keeps water pressure steady at every fixture.

In rare cases the pre-charge can be reset with a tire gauge and air pump. Most of the time a waterlogged tank means the internal bladder has ruptured, and replacement is more cost-effective than repair. We diagnose the cause and give you a written quote before any work.

Yes. A.J. LeBlanc Heating handles the whole pressure side of the well system, including the tank, pressure switch, pressure gauge, check valve, and pump wiring. If the submersible pump itself has failed, we coordinate with a licensed well drilling contractor for the pump pull and replacement.

We install Amtrol Well-X-Trol, Flexcon, and Pentek bladder and captive-air pressure tanks throughout Southern NH. Tank selection is based on pump GPM, drawdown requirements, and the available space in the mechanical room.

A constant pressure pump is a variable-speed well pump (Grundfos SQE, Goulds Aquavar, and similar) that ramps up and down to hold a steady 50 to 60 PSI no matter how much water is being used. Standard well pumps run on a pressure switch that swings between 30 and 50 (or 40 and 60) PSI, which you feel as fluctuating pressure in the shower or at fixtures. Constant pressure is worth it for larger homes, two-story houses, irrigation, and homes where multiple fixtures run at the same time.

Yes. Homes at the end of a city water line, on a hill, or with multiple stories often see low or fluctuating municipal pressure. A.J. LeBlanc Heating installs city water booster pumps with a small expansion tank and pressure controller that bring incoming pressure up to a steady 50 to 60 PSI throughout the home. We size each system to household demand and the existing service line.
