Sewage Pump Float Switch FAQS

A sewage pump float switch is a handy device that helps control the water level in a sewage pit or tank. It automatically turns the pump on or off to prevent overflows or dry runs, keeping everything running smoothly and protecting the pump.

How It Works:

  • The float switch moves up and down with the water level, acting as a sensor.

  • When the water rises too high, the switch turns the pump on.

  • As the water level drops, the switch turns the pump off.

Why It’s Important:

Prevents Overflows – Stops sewage from spilling over by turning the pump on at the right time.
Protects the Pump – Keeps the pump from running dry, which can cause damage.
Saves Energy – Ensures the pump only runs when needed, making it more efficient.

Types of Float Switches:

  • Tethered Float Switches – Have a floating ball attached to a switch, rising and falling with the water.

  • Multi-Contact Float Switches – Can trigger different functions, like high-water alarms or extra safety features.

Where They’re Used:

Float switches are found in sewage pumping stations, drainage systems, and wastewater plants, helping to keep water moving safely and efficiently.

If a sewage pump float switch stops working, your pump might not turn on when needed, which could lead to sewage backups and even flooding. On the other hand, if the switch gets stuck in the “on” position, the pump might run nonstop, which can cause overheating and damage.

What Happens When a Float Switch Fails?

Pump Doesn’t Turn On – If the float switch doesn’t activate, sewage can build up and overflow, causing a mess and potential property damage.

Pump Runs Nonstop – A stuck float switch can cause the pump to keep running, which may lead to:
Overheating & Motor Burnout – Pumps aren’t designed to run all the time, and doing so can cause serious damage.
Higher Energy Bills – A constantly running pump wastes electricity, increasing costs.

Why Sewage Backups Are a Big Problem

Water Damage – Flooding can ruin floors, walls, and belongings.
Health Risks – Sewage contains harmful bacteria and viruses.
Mold & Mildew – Damp conditions can lead to mold growth, which is bad for both your home and health.

How to Prevent Issues

Regularly check and maintain your float switch to catch problems early.
If your pump isn’t turning on (or won’t turn off), contact a professional to inspect and fix it.

Taking care of your pump system can save you from costly repairs and major headaches down the road!
