Is It the Well Pump or the Pressure Tank?
The two parts fail differently. Match your symptom to the right culprit before you spend money on the wrong fix.
A well pump problem and a pressure tank problem look similar at the faucet but feel different at the equipment. A bad pump usually means slow pressure build, no water at all, or pumping air. A bad tank usually means rapid short-cycling, surging pressure, or a tank that feels heavy and sloshes when tapped. Replacing the wrong one is the single most common mistake we see homeowners and handymen make.

How a service call works
- 1Free phone diagnosis
We walk through symptoms, water pressure, sounds, and system age to narrow the problem before we roll a truck.
- 2On-site test
We check voltage at the pressure switch, draw amps on the pump, and verify pressure tank pre-charge before opening anything.
- 3Written estimate
You see the recommended scope, repair vs replacement, parts, and labor in writing before any work begins.
- 4Repair or replacement
We carry common pumps, tanks, switches, and check valves on the truck so most no-water calls finish the same day they started.
- 5System test and follow-up
We cycle the system, confirm pressure holds, shock-chlorinate when needed, and stand behind the work with a labor warranty.
What does it cost?
Tank replacement: $400 to $1,200 installed. Pump replacement: $1,500 to $3,500. Diagnosis is included with our standard service call — we don't replace anything until we've confirmed which one failed.

Frequently asked
How can I tell if my pressure tank is bad?
Tap the tank from top to bottom. A healthy tank sounds hollow on top and solid on the bottom. A waterlogged tank sounds solid the whole way. Also: pumps that cycle on/off every 10 to 30 seconds during steady use almost always have a failed tank.
How can I tell if the pump is bad instead?
Slow pressure build (over 2 minutes from cut-in to cut-out), pumping air, sand or sediment, audible motor noise, or no response at all when the switch closes. The tank is fine but the pump can't fill it.
Can a bad tank kill the pump?
Yes — that's the most common way pumps fail early. Short-cycling on a waterlogged tank burns out motor windings and starting capacitors. Replacing only the pump without fixing the tank just kills the new pump too.
Which one usually fails first?
Pressure tanks usually fail first. They use a rubber diaphragm that eventually ruptures (8 to 15 years). Pumps last roughly the same span but tanks are cheaper to fail.
How much does well pump repair cost?
Most residential well pump repairs in central NC fall between $400 and $1,800 depending on the failed part, well depth, and whether the pump has to come out of the well. A full submersible pump replacement (pump, wire, drop pipe, and labor) typically runs $1,500 to $3,500. Every job gets a written on-site estimate before any work begins.

Can you come out the same day?
Yes. No-water calls get same-day priority across the Piedmont Triad and our phone is answered 24/7. Most emergency calls are reached on-site within a couple of hours of the first call.
Do you warranty the work?
Yes. You get the full manufacturer warranty on the pump or tank plus our own labor warranty on the install. We answer the phone after the job is done.
