Why Did My Well Pump Stop Working?

When your well pump quits, you're not just dealing with an inconvenience — you've lost your entire water supply. No showers, no toilets, no water for livestock or irrigation. The most common reasons a well pump stops working include a tripped breaker or blown fuse, a failed pressure switch, a waterlogged pressure tank, a burned-out pump motor, or a drop pipe leak sending water back down the well instead of into your house.

Here's what most homeowners don't realize: roughly 70% of the "dead pump" calls we run in the Fort Worth area turn out to be something other than the pump itself. A $15 pressure switch or a bad capacitor can mimic a completely failed pump. That's why proper well pump troubleshooting matters — and why you want a well contractor, not a general plumber, diagnosing the problem.

How Much Does Well Pump Repair Cost?

Straightforward well pump repairs in North Texas typically run $200–$800 depending on the issue. Pressure switch replacements, capacitor swaps, and wiring fixes fall on the low end. If the pump itself needs to be pulled from the well — which requires a service rig and crew — expect $800–$2,500+ depending on well depth and what we find down there.

Compare that to a full well pump replacement, which runs $2,000–$6,000+ installed. A proper diagnosis can save you thousands by confirming whether a repair will get you back in water or whether it's time for a new pump.

The Legacy Water Well Repair Process

When Justin and the crew show up, we don't start guessing. We run a systematic diagnostic starting at the electrical panel and working our way down to the pump — because the cheapest fix is always the one closest to the surface.

Step 1: Electrical & Controls Check

We test voltage at the panel, verify the pressure switch operation, check the pump control box and capacitors, and inspect all wiring for damage, corrosion, or rodent chew. This alone solves about 40% of no-water calls without ever touching the pump.

Step 2: Pressure Tank Evaluation

A waterlogged pressure tank causes short-cycling — the pump kicks on and off every few seconds. That burns out motors fast. We check tank air charge with a gauge (not by shaking it or guessing) and evaluate the bladder integrity. A failed tank is a $300–$600 fix that saves your pump from a premature death.

Step 3: Well & Pump Performance Testing

If the surface equipment checks out, we move to the well itself. We measure static water level, pumping rate, and drawdown to confirm the well is producing properly. A pump that "stopped working" might actually be a well that's dropped in water level — a completely different problem with a completely different solution.

Step 4: Pump Pull & Inspection (If Needed)

When diagnostics point to the pump or drop pipe, we bring in the service rig to pull the pump assembly. For deep wells with submersible pumps set at 200–400 feet, this is a full-day operation requiring specialized equipment. We inspect the motor, impellers, check valve, and pipe connections before recommending repair versus replacement.

Signs Your Well Pump Needs Repair

Most pump failures don't happen overnight. They send warning signs for weeks or months before the water stops completely. Here's what to watch for — and what each symptom usually means:

• No water at all — Could be electrical (breaker, pressure switch, control box), a failed pump motor, or a well that's gone dry. We diagnose before we prescribe.
• Pump runs but no pressure builds — Typically a failed check valve, cracked drop pipe, worn impellers, or a well that can't keep up with the pump's demand. Common in older North Texas wells.
• Short-cycling (pump kicks on/off rapidly) — Almost always a waterlogged pressure tank or a failing pressure switch. Left unchecked, this kills pump motors. If you hear your pump cycling every 30 seconds, call us today.
• Sputtering or air in the lines — The pump may be set too close to the water level, or the water table has dropped. Could also indicate a cracked casing letting air into the system.
• Discolored or sandy water — A pump sitting too low can pull sediment. Worn impellers lose efficiency and stir up the bottom. Sometimes this means the well screen has failed.
• High electric bills — A struggling pump draws more amps. If your electric bill jumped and nothing else changed, a failing well pump is a prime suspect.
• Clicking or humming at the pressure switch — The pump is trying to start but can't. Usually a bad capacitor, seized motor, or low voltage issue.

Catching these problems early is the difference between a $300 repair and a $4,000 replacement. Know the signs your well pump is failing and act before you're standing in the shower with no water.

Well Pump Specialists — Not General Plumbers

There's a big difference between a plumber who "also does well pumps" and a dedicated well pump contractor. Plumbers work with city water systems — pressurized supply lines, fixtures, drains. Well systems are a completely different animal: submersible motors, pressure tanks, control boxes, check valves, drop pipe, and the well itself.

Legacy Water Well is a licensed water well contractor serving the Fort Worth and North Texas area. Justin Holt and the team work on wells every single day — not as a sideline. That means:

• Proper diagnostic equipment — We carry amp meters, megohm meters for motor testing, pressure gauges, and water level indicators. Not just a multimeter and a guess.
• Our own service rig — We don't subcontract pump pulls. Our rig handles wells up to 1,000+ feet deep.
• Parts on the truck — Pressure switches, capacitors, control boxes, and common pump sizes are stocked so most repairs are done the same day.
• We know North Texas wells — The Trinity Aquifer, the Paluxy formation, the typical well depths and water quality issues in Tarrant, Parker, Wise, Denton, and Johnson counties. That local knowledge matters when diagnosing problems.

We Service All Well Pump Types

Whether you have a 1/2 HP submersible pump in a shallow residential well or a 25 HP turbine on an agricultural or commercial well, we repair and service them all. Brands we commonly work on include Grundfos, Franklin Electric, Goulds, Myers, Pentair Berkeley, and Sta-Rite.
