If your home relies on a well pump system and the water has suddenly stopped flowing, it can be frustrating and confusing. A well pump is the heart of your water supply – and when it fails unexpectedly, your entire household feels the impact.
Whether you live in Reading,Pottstown, Boyertown, Fleetwood, Shoemakersville, or Kutztown, understanding why a well pump stops working and how to troubleshoot it can save you time, money, and headaches.
Let’s break down how a well pump system works, the most common reasons for failure, and when it’s time to call the experts at Berks Plumbing and HVAC Specialist
How a Well Pump System Works
Before we jump into the causes of pump failure, it helps to understand what’s happening behind the scenes when you turn on your faucet.
Key Components
Every well pump system – whether it’s in Fleetwood, Bethel, or Sinking Spring – has three critical components: a pressure switch, a pump motor, and a storage tank.
Pressure Switch
This small but crucial device monitors your water pressure. When pressure drops below a certain level (usually 30–40 PSI), the switch activates the pump. Once the pressure reaches 50–60 PSI, it shuts the pump off again.
If this switch fails, your pump may not turn on at all – one of the most common issues homeowners face when they say their well pump is not working.
Pump Motor
The motor drives the pump, drawing water from the well and pushing it through your home’s plumbing. Submersible pumps (often used in deeper wells) can last 10–15 years, while jet pumps (used in shallower wells) may need service sooner.
A burnt-out motor due to overheating or electrical failure is one of the leading well pump failure causes.
Storage Tank
Also known as a pressure tank, it stores pressurized water to maintain steady flow and prevent short cycling. If the tank malfunctions, your pump may turn on and off rapidly – leading to premature wear.
Common Reasons a Well Pump Fails Unexpectedly
When your well pump stops suddenly, the root cause is usually electrical, mechanical, or environmental. Below are the top issues we diagnose during Berks well pump repair calls.
Electrical Problems
Electrical faults are among the most frequent reasons for sudden pump shutdowns. These problems can occur anywhere between your main panel and the pump itself.
Tripped Circuit Breakers
A simple tripped breaker could be the culprit – especially after a power surge or lightning strike. Resetting it might temporarily restore function, but repeated tripping signals a deeper issue.
Causes of Overheating
Pump motors can overheat if they run continuously – often caused by a stuck pressure switch or dry well. When overheated, the pump’s built-in thermal overload shuts it off automatically.
Pump Overuse or Short Cycling
If your system frequently starts and stops, it’s called short cycling. This can happen due to low air pressure in the tank or small leaks in the plumbing. Over time, short cycling wears out the motor faster.
Pressure Switch Malfunction
A faulty pressure switch can make your system behave unpredictably. It might fail to detect low pressure or become corroded inside – both of which prevent your pump from turning on.
Many homeowners in Wyomissing, Exeter, or Mohnton report intermittent water supply issues, which often trace back to this simple part.
Dried-Up Well or Low Water Table
During dry seasons or droughts (especially common in Berks and Lebanon Counties), the water table may drop below the pump intake level. If the pump runs dry, it can burn out quickly.
A low-water cut-off switch can prevent this by shutting down the system when water levels get too low – a worthwhile upgrade during well pump installation in Fleetwood or Shoemakersville.
Clogged Intake or Pipes
Mineral buildup, sediment, or small stones can clog your well’s intake screen or pipes, restricting water flow. Signs include sputtering faucets or reduced water pressure throughout the house.
If you live in areas like Boyertown, Douglasville, or Birdsboro, where the groundwater can be rich in minerals, this problem is especially common.
Pump Motor Burnout
Over time, the pump motor may simply wear out. If it’s been more than 10 years since your well pump installation in Wernersville, motor replacement might be the most cost-effective solution.
Warning Signs Before a Pump Completely Fails
Well pumps rarely stop working overnight – there are usually warning signs you can catch early.
Sputtering Faucets
If your faucets sputter or spit air before water flows, it could mean air is entering the system through a failing valve or low water level.
Dirty or Cloudy Water
Sediment or discoloration in your water may indicate that your pump is pulling from the bottom of the well – a sign of low water levels or intake clogging.
Sudden Low Pressure
If your water pressure drops suddenly, it’s often related to the pressure switch, clogged pipes, or pump performance.
Residents in Palmyra, Annville, and Pottstown often report this symptom before complete system shutdowns.
Troubleshooting Steps You Can Try
Before calling a professional, there are a few safe and simple checks you can do yourself.
Resetting the Breaker
Head to your electrical panel and see if the breaker controlling the well pump is tripped. Reset it once – but if it trips again, don’t force it. Repeated tripping could indicate wiring or motor failure.
Checking Pressure Switch Settings
If you’re comfortable doing so, inspect your pressure switch. Make sure it’s free of debris or insects (a common issue). Tapping the switch lightly can sometimes help it reconnect, but if that doesn’t work, it likely needs replacement.
