Well Pump Repair & Replacement in Conroe, TX | Conroe Water Well Service
A well pump failure can leave a home without water within minutes, and the cause is not always obvious. At Conroe Water Well Service, we diagnose and resolve well pump problems quickly, from weak pressure to complete water loss, so homeowners in Conroe, TX are not left guessing about what went wrong.
Well pumps wear down over time due to sediment, electrical issues, or mechanical failure, and the right response depends on the specific cause. We inspect the entire system before recommending a repair or replacement, so homeowners understand exactly what their well needs and why.
Our team works throughout Conroe and the surrounding Montgomery County area, addressing both minor pump issues and full system replacements. This post covers the signs of pump failure, what to expect during repair or replacement, and how to keep a well system running reliably for years to come.

Well Pump Problems That May Require Repair
Well pumps rarely fail without warning. Most systems show clear signs before a complete breakdown, and we can often catch these issues early when homeowners know what to watch for.
No Water or Intermittent Water From the Well Pump
A complete loss of water usually points to a few common culprits. We typically check these first:
- Tripped breaker or electrical fault — power interruptions to the pump motor
- Failed pressure switch — the switch that tells the pump when to turn on
- Broken pump motor — especially in older submersible units
- Water table drop — seasonal changes can lower the well below the pump intake
- Stuck or failed check valve — prevents water from returning to the tap
Intermittent water often signals a different problem. This can mean the pump is cycling improperly or air is entering the system. We also see this when a pressure tank has lost its air charge, causing the pump to short-cycle instead of maintaining steady flow. Sandy or discolored water sometimes accompanies these symptoms, which can indicate the pump has dropped closer to the well's sediment layer.
Well Pump Runs Constantly, Loses Output, or Will Not Build Pressure
A pump that runs without stopping is working harder than it should. We usually find this traces back to a leak in the system, a failing pressure switch, or a pump that's undersized for current household demand.
Constant cycling wears down the motor faster and increases utility costs. Left unaddressed, it shortens the pump's lifespan considerably.
Loss of water pressure or an inability to build pressure at all often points to:
- Worn pump impellers — reduced efficiency in moving water
- Clogged well screen — restricts water flow into the system
- Failing pressure tank bladder — can't hold the correct air-to-water ratio
- Pipe or fitting leaks — pressure escapes before reaching the tap
We recommend addressing pressure problems quickly, since a struggling pump is more likely to overheat or burn out.
Well Pump Diagnostics, Repair & Pump Pulling
We rely on systematic diagnostic procedures to identify the exact cause of a pump failure before recommending repair or replacement. Once we've confirmed the issue, we use the right pulling equipment and inspect every component that comes out of the well.
Submersible Pump Diagnostics and Electrical Testing
We start every diagnostic call by checking pressure switch settings and tank pressure readings. Low or fluctuating pressure often points us toward pump wear or a failing pressure switch.
Our technicians use a multimeter to test motor windings for continuity and check for grounding issues. We measure amperage draw against the motor's rated specifications to detect overload conditions or bearing failure.
We also inspect the control box and capacitor on single-phase systems, since these components fail frequently and mimic pump motor problems. Voltage drop testing along the circuit helps us rule out wiring issues before condemning the pump itself.
Common electrical issues we check for:
- Faulty pressure switches
- Failed capacitors or relays
- Damaged control boxes
- Grounded or shorted motor windings
- Corroded wire connections
Pump Pulling, Drop Cable, and Drop Pipe Inspection
When electrical testing confirms a pump failure, we pull the entire assembly using a well rig or hoist rated for the well depth and pump weight. We handle drop pipe sections carefully during removal to avoid cross-threading or dropping equipment back into the casing.
As we bring each section up, we inspect the drop cable for insulation damage, splice failures, and rodent chew marks. We also check drop pipe for corrosion, scale buildup, and thread wear that could cause future leaks.
We document pipe condition and cable integrity before reinstalling the pump or a replacement unit. This inspection step helps us catch secondary problems that would otherwise cause repeat service calls within months.
Well Pump Replacement & Proper Pump Sizing
Replacing a well pump is a bigger job than repairing one, and getting the sizing right matters as much as the installation itself. We look at both when to replace instead of repair and how we calculate the correct pump specifications for your well.
When to Repair a Well Pump vs. Replace It
We weigh a few factors before recommending replacement over repair.
- Age of the pump – Most submersible pumps last 8-15 years. If yours is near or past that range, we usually recommend replacement rather than sinking money into a repair.
- Frequency of breakdowns – Repeated failures within a short period signal a pump nearing the end of its service life.
- Cost comparison – If a repair costs more than 50% of a new pump installation, we typically advise replacement.
- Motor burnout – A burned-out motor often means the entire unit needs replacing.
- Changing water demand – If your household or business water usage has increased, we may recommend a properly sized replacement rather than repairing an undersized pump.
Sizing a Replacement Pump for Well Depth, Flow, and Total Dynamic Head
We size every replacement pump based on three core measurements: well depth, required flow rate, and total dynamic head (TDH).
Well depth tells us how far the pump needs to lift water. Flow rate, measured in gallons per minute, is based on your household or commercial fixture count and peak demand. TDH accounts for vertical lift, friction loss in the piping, and pressure needed at the point of use.
We calculate these figures using your well's static water level, drawdown data, and pipe diameter. An undersized pump won't meet peak demand; an oversized one cycles too often and wears out prematurely. We match the pump curve to your well's actual output.
Planning Well Pump Service in Conroe
Well pumps in Montgomery County vary in type, depth, and setup, so the repair or replacement approach depends on your specific system. Knowing what kind of pump you have and having key details ready before you call helps us diagnose issues faster and recommend the right fix.
Submersible vs. Jet Pump Repair and Replacement
Submersible pumps sit down in the well itself, below the water line, and are the more common choice for deeper wells in this area.
Jet pumps stay above ground, usually in a well house or utility room, and pull water up through suction. Each type has different failure points.
Submersible pumps often fail due to worn bearings, damaged seals, or electrical issues in the motor windings. Jet pumps more commonly develop problems with the impeller, pressure switch, or loss of prime.
We assess which type you have and its age before recommending repair versus full replacement. In many cases, a pump older than 10-15 years with a major mechanical failure is more cost-effective to replace than repair.
What to Provide When Requesting Well Pump Repair or Replacement
When you contact us, a few details speed up the process considerably. We ask for:
- Pump type, if known (submersible or jet)
- Well depth and approximate age of the current pump
- Symptoms, such as no water, low pressure, cycling on and off, or unusual noise
- Recent changes, like new appliances, irrigation additions, or a recent power outage
- Property access details, including gate codes or well house location
If you have any past service records or the pump's model number, that helps us match parts correctly. Photos of the wellhead or pressure tank also give us useful context before we arrive on site.
