Well Water Pressure Problems in Alamance County

Low water pressure on a private well in Alamance County is one of the most common service calls we take, and also one of the most misdiagnosed. Homeowners in Burlington, Graham, Mebane, and Elon often assume the pump is failing when the real problem is a pressure tank that lost its air charge, a clogged sediment filter, or a pressure switch that drifted out of adjustment.

Spending an hour on diagnosis up front saves real money. A new pressure tank is a fraction of the cost of a pump replacement, and a $40 pressure switch can solve what looked like a major failure.

TL;DR: Pressure problems almost always trace back to one of five things: the pressure tank, the pressure switch, a clogged filter, a leak, or the pump itself. Test them in that order.

How a Healthy Alamance County Well System Should Feel

A well-tuned residential system in Alamance County delivers steady pressure between 40 and 60 psi at the tank gauge, with the pump cycling on at the cut-in pressure and off at cut-out. Showers should not pulse. Two fixtures running together should not collapse pressure at either one. The pump should not click on every few seconds while only one tap runs.

If any of those conditions are off, your system is telling you something. The trick is reading the signal correctly.

Step 1: Check the Pressure Tank First

More than half the low-pressure calls we run in Burlington and Graham come back to the pressure tank, not the pump. A bladder tank that loses its air charge cannot store water under pressure, so the pump short cycles and the house never feels strong.

With the pump powered off and a fixture drained, the air pressure inside the tank should read 2 psi below your cut-in pressure (typically 28 psi for a 30/50 system or 38 psi for a 40/60 system). If you tap the side and the whole tank rings hollow at the top, that part is correct. If it rings hollow all the way down, the bladder has failed and the tank needs replacement.

Step 2: Test the Pressure Switch

The pressure switch is the small gray box, usually mounted near the tank, that tells the pump when to start and stop. Switches drift over time, get clogged with sediment in the small port that senses pressure, or develop pitted contacts that arc and stick.

A switch that will not cut out at the right pressure can make the system feel weak even when the pump is fine. A switch with corroded contacts can leave the pump off when it should be running. Replacement is straightforward but should be done with the breaker off and the system depressurized.

Step 3: Look for the Easy Restrictions

Before assuming a system-wide problem, narrow down where the pressure is weak. If only one fixture is weak, the problem is between the wall and that fixture, not the well. Common culprits include a clogged aerator, a sediment-filled cartridge filter, a partially closed shutoff valve, or a kinked supply line.

Whole-house pressure that drops slowly over months almost always traces back to a sediment filter that has not been changed. We have pulled filters in Mebane homes that looked black with iron and were strangling a perfectly healthy pump.

Step 4: Hunt for Leaks

A pump that runs when no one is using water is a leak until proven otherwise. Shut off every fixture, watch the pressure gauge for 30 minutes, and see if it drops. If it does, water is escaping somewhere: a running toilet flapper, a leaking water heater, a frost-free hydrant, a broken irrigation valve, or a pinhole in a buried supply line.

Underground leaks between the well and the house are the meanest version of this problem. They cost real money in pump wear and electricity. Wet spots in the yard that never dry out, or unusually green grass in a line from the well to the foundation, are clues.

Step 5: Then Consider the Pump

If the tank holds air, the switch is set correctly, filters are clean, and there are no leaks, only then should you suspect the pump. A weakening submersible pump usually shows three patterns: longer fill times to reach cut-out, lower maximum pressure even with the pump running, and rising amp draw at the breaker.

Our team handles well pump repair across Alamance County and the surrounding service area, and a proper diagnosis includes amp readings, voltage checks at the pressure switch, and tank performance under load, not just guesswork.

Common Mistakes That Make Pressure Problems Worse

We see the same handful of well-intentioned mistakes in Alamance County homes:

• •Cranking the pressure switch higher to mask weak pump output, which burns the motor faster.
• •Adding a booster pump after the pressure tank instead of fixing what is wrong upstream.
• •Replacing the tank without testing the pump or switch, then watching the problem return.
• •Installing a whole-house filter without a bypass, so a clogged cartridge takes the whole house down.
• •Ignoring a slow leak in an irrigation zone that runs the pump 18 hours a day.

When to Stop Diagnosing and Call

If the tank is good, the switch is good, filters are clean, no leaks are visible, and pressure is still poor, it is time to bring in a pump tech. Live electrical work at the pressure switch, pulling a submersible pump, and well casing work are not DIY territory.
