Well Pump Not Working? Quick Checks Before Calling
Before calling for emergency service, a few quick checks can save you an unnecessary service visit — check your main 240V breaker, listen for clicking at the pressure switch, and watch for a waterlogged tank using a simple knuckle-tap test. If basic power and switches aren't the issue, the failure usually stems from a seized down-hole pump motor, blown control box capacitors, or a ruptured internal tank bladder.
Why Call Star Plumbing for Well Repair
- electrical_services Surface Diagnostics First: We test winding ohms, switches, and capacitors first so you never pay for an unneeded pump pull.
- local_shipping OEM Inventory On-Board: We carry OEM Franklin & Goulds replacement control boxes and Square D pressure switches on every truck for same-day repairs.
Why Northern Colorado Well Owners Choose Star Plumbing
Methodical electrical diagnostics, upfront flat-rate pricing, and heavy-duty hoist equipment for safe pump replacement.
Diagnostic-First Approach — No Unnecessary Pump Pulls
Many plumbing contractors immediately quote an expensive multi-thousand-dollar pump pull when the actual fault is an easily replaceable $250 pressure switch, a burnt start capacitor in the control box, or a waterlogged bladder tank. At Star Plumbing, we measure winding resistance with megohmmeters, test voltage drop, and isolate every electrical component on the surface first. You only pay for a pump pull when down-hole equipment is genuinely damaged.

Diagnosing Your Well: Symptoms & Likely Solutions
Use this symptom matrix to understand the root cause behind your private well system issues:
| Observed Symptom | Most Probable Cause | Recommended Service Action | Urgency Level |
|---|---|---|---|
| Total Loss of Water Pressure (Zero Flow) | Tripped breaker, burned pressure switch, dead start capacitor, or seized submersible motor. | Surface electrical diagnostics first; replace switch/control box or pull pump. | High / Immediate |
| Pump Clicks Rapidly (Short-Cycling Every 5–15 Sec) | Waterlogged pressure tank; internal rubber bladder ruptured and lost air cushion. | Pressure tank replacement & air pre-charge calibration to save motor. | Medium (Saves Motor) |
| Sputtering Taps / Air in Water Lines | Failed check valve, cracked drop pipe near wellhead, or low water table near intake. | Check valve replacement, drop pipe pressure test, or pump lowering. | Medium |
| Pump Runs Continuously Without Stopping | Stuck pressure switch, underground pipe leak between well & house, or worn impellers. | Switch calibration, plumbing leak detection, or pump replacement. | High (Overheating Risk) |
| Cloudy, Sandy, or Silty Water | Damaged well casing, failing intake screen, or seasonal alluvial water table drawdown. | Intake screen repair, pump repositioning, or sediment filter installation. | Standard |
water Submersible Well Pumps (Deep Wells)
Installed at the bottom of the well casing submerged beneath the water table. The pump pushes water upward, making it dramatically more efficient and capable of handling depths from 80 to 600+ feet.
- check Lifespan: 10–15+ years
- check Depth Rating: Up to 600+ ft
- check Noise: Completely silent inside home
- check Efficiency: High volume (10–25+ GPM)
precision_manufacturing Jet Pumps (Shallow Wells)
Mounted above ground inside a basement, utility room, or well house. Jet pumps create suction to pull water up from shallow water tables (typically under 25–80 feet depth).
- check Lifespan: 8–12 years
- check Depth Rating: Ideal for <25 ft (convertible to 80 ft)
- check Accessibility: Easy surface servicing without pulling
- check Efficiency: Moderate volume (5–12 GPM)
What Does Well Pump Repair Cost in Fort Collins?
Private well system repair costs depend entirely on whether the issue is surface-accessible (pressure switch, control box, pressure tank) or requires motorized pulling equipment to retrieve a submerged pump from 200+ feet depth.
Because we perform exhaustive electrical diagnostics before touching a drop pipe, you never pay for a pump pull unless the motor or down-hole wiring is genuinely compromised.
Frequently Asked Questions — Well Pumps in Northern Colorado
Why did my well pump suddenly stop working and leave me with no water?
The most common causes of complete water loss are: (1) A tripped 240V double-pole circuit breaker, (2) Burnt or corroded electrical contact points on the pressure switch, (3) A blown start capacitor or voltage relay inside the control box, (4) A seized down-hole submersible motor, or (5) A ruptured pressure tank bladder causing the motor to rapidly overheat and shut down on thermal overload. Star Plumbing tests voltage, current draw, and winding resistance on the first visit to isolate the failure.
How do I know if it's my well pump or my pressure tank that failed?
If your pump "short-cycles" (clicks on and off rapidly every few seconds whenever you open a faucet), the pressure tank's internal bladder has failed and become waterlogged. If you have complete loss of water and the circuit breaker hasn't tripped, the issue is almost always electrical (pressure switch, control box) or mechanical (submersible pump motor, check valve, drop pipe).
How long does a submersible well pump last in Northern Colorado?
Submersible well pumps typically last 10 to 15 years in Colorado. Lifespan depends heavily on groundwater mineral hardness, well depth, and how often the system cycles. Maintaining correct pressure tank air pre-charge prevents rapid cycling and significantly extends motor life.
Can I pull and replace my own well pump?
We strongly advise against DIY pump pulls. A 200-to-400-foot well column filled with water, heavy drop pipe, pump motor, and submerged wiring can weigh hundreds of pounds. DIY attempts frequently result in dropped equipment, snapped drop pipes, or severed underwater cables. We utilize specialized motorized pulling machines to ensure safe, controlled removal and installation.
What is a constant pressure (VFD) well system and is it worth the upgrade?
A Variable Frequency Drive (VFD) constant pressure controller monitors household water demand electronically and adjusts pump motor RPM in real time. Instead of the wide 20 PSI pressure swings of traditional 30/50 switches, a VFD maintains steady, city-like 55–60 PSI water pressure across all showers, faucets, and irrigation zones simultaneously.
What causes sputtering air or cloudy, sandy water from my faucets?
Air sputtering usually points to a failed check valve allowing water to drain back into the well casing, a pinhole leak in the drop pipe, or the seasonal water table dropping near the pump intake. Sandy or silty water indicates a failing intake screen, a compromised well casing, or pump placement set too low in the sediment column.
Do you service rural acreages and mountain properties outside Fort Collins?
Yes. We regularly service rural acreages and mountain properties throughout Larimer and Weld Counties, including remote canyon, foothill, and unpaved-access properties.
Northern Colorado Hydrogeology & Well Conditions
Plumbing private wells in Larimer and Weld counties requires understanding distinct regional geology — from the fractured granite aquifers of the foothills to the alluvial sand-and-gravel formations along the Poudre River plains.
Foothills & Mountain Casing
In the foothills and canyon country west of Fort Collins, wells often drill 200 to 450+ feet through granite fissures. Pumping at these depths requires heavy-duty multi-stage motors with high dynamic head ratings and surge arrestors for mountain electrical grids.
High Mineral Hardness & Scaling
Groundwater across Fort Collins and Larimer County frequently tests between 12 and 30+ grains per gallon of hardness, along with dissolved calcium and iron. This causes scale buildup on impellers and pressure switch nipples that require specialized descaling.
Frost Line Freeze Protection
Larimer County building code requires water service lines to sit at least 36 to 48 inches below grade. We ensure pitless adapter couplings, insulated well house plumbing, and check valve locations are properly engineered against deep Colorado freezes.
