Pressure Switch Not Working? Here’s How to Tell and What to Do
Your pressure switch is the small but crucial part of your well system that tells your pump when to turn on and off. When it fails, you might notice no water flow, low pressure, or a pump that won’t stop running.
At Galan Well Drilling & Pump Inc., we help homeowners across Tampa, Riverview, Brandon, Plant City, Seffner, and nearby communities troubleshoot and replace faulty pressure switches quickly and safely.
✅ What the Pressure Switch Does
The pressure switch monitors the pressure in your tank and automatically controls the pump. When pressure drops below a set level, the switch activates the pump. Once pressure reaches the upper limit, it shuts the pump off.
When the switch fails, that automatic balance disappears—leading to multiple system problems.
✅ Common Signs of a Faulty Pressure Switch
-
Pump Won’t Turn On or Off
-
If your pump doesn’t start when water pressure drops, the switch may not be engaging.
-
If the pump won’t shut off, the contacts could be stuck.
-
-
Low or Fluctuating Water Pressure
-
A weak or inconsistent signal from the switch causes irregular pump cycling.
-
-
Burned or Corroded Contacts
-
✅ Over time, moisture and electrical arcing can damage the metal contacts inside the switch.
-
-
Clicking Sounds but No Water Flow
-
Clicking with no response usually means the switch is trying to engage but failing to send power properly.
-
-
Visible Rust or Water Damage
-
Florida’s humidity can corrode the housing and wiring of outdoor pressure switches.
-
✅ Why Pressure Switches Fail in Florida
Florida’s coastal humidity and frequent storms accelerate corrosion and electrical wear. In areas like Tampa, Wesley Chapel, and Valrico, we commonly see:
-
Rust from moisture exposure
-
Electrical surges from lightning strikes
-
Dust and debris buildup in the contacts
-
Loose wiring from vibration and use
✅ What to Do If You Suspect a Bad Pressure Switch
-
Turn Off Power to the Pump
-
Prevent electrical hazards or motor damage.
-
-
Check the Switch Housing
-
Look for rust, water, or insect buildup.
-
-
Listen for Clicking
-
Clicking without water pressure response often confirms switch failure.
-
-
Call a Licensed Technician
-
Pressure switches involve live electrical components and should only be replaced by professionals.
