What Does a Pressure Switch Do?
The pressure switch acts as the "brain" of your well system. It monitors water pressure inside the pressure tank and tells the well pump when to turn on and off.
For example:
When water pressure drops to 40 PSI, the switch turns the pump on.
When pressure reaches 60 PSI, the switch turns the pump off.
This cycle happens hundreds or even thousands of times each month.
Why Pressure Switches Fail
Florida's heat, humidity, rain, insects, and outdoor installations create the perfect environment for pressure switch problems.
Common issues include:
✔ Corroded electrical contacts
✔ Burned contact points from electrical arcing
✔ Ants and insects nesting inside the switch
✔ Rust buildup from moisture exposure
✔ Pressure port clogging from sediment or iron buildup
✔ Loose electrical connections
When these problems occur, the switch may fail to send power to the well pump, leaving you without water.
The Cost of Waiting
A pressure switch is one of the least expensive components in a well system, but when it fails it can mimic much larger problems such as:
Bad well pumps
Failed control boxes
Pressure tank issues
Electrical failures
Water supply interruptions
Many homeowners panic when they suddenly have no water, only to discover the problem was a worn-out pressure switch.
Why We Recommend Annual Replacement
Replacing the pressure switch once per year provides several benefits:
Improved Reliability
A fresh switch reduces the risk of unexpected water outages.
Protects Your Well Pump
Failing switches can cause pumps to short cycle, overwork, or run improperly, shortening pump life.
Prevents Emergency Service Calls
A scheduled replacement is far less expensive and stressful than an after-hours emergency.
Provides an Opportunity for a Full System Inspection
During replacement, your plumber can inspect:
Pressure tank condition
Pressure gauge accuracy
Wiring connections
Well piping
Filtration equipment
Signs of leaks or corrosion
