We specialize in ejector pump repair and installation, quickly resolving basement bathroom backups, tripped alarms, and worn-out pump units to restore safe, reliable wastewater removal for your home or business.
An ejector pump moves wastewater from a basement bathroom, laundry room, or lower-level fixture up to your main sewer or septic line, whenever gravity alone can't get the job done. It's the reason a basement bathroom can flush at all — and when it fails, sewage has nowhere to go but back into your home.
At Nova Drain & Plumbing Services London, our licensed plumbers repair, install, and maintain sewage ejector pump systems across London, Ontario — from the pump and basin to check valves, discharge lines, and high-water alarms.
Wastewater Enters the Basin
Drain lines from a basement toilet, sink, or laundry unit feed into a sealed ejector pit.
The Float Switch Triggers the Pump
Once the basin reaches a set level, the pump engages automatically.
Waste Is Discharged to the Sewer Line
A check valve keeps wastewater from flowing back into the basin between cycles.
Ejector pumps rarely fail without warning. Catching these symptoms early can prevent a full sewage backup.
High-Water Alarm Is Sounding
An active alarm means the basin is filling faster than the pump can clear it.
Slow or Gurgling Basement Drains
Gurgling from a basement toilet or floor drain often signals a struggling pump or clogged line.
Sewage Odor Near the Basin
A persistent smell usually points to a failing seal, cracked lid, or vent problem.
Pump Runs Constantly or Not at All
A stuck float switch can leave the pump cycling nonstop or never turning on.
Grinding or Rattling Noises
Unusual noise from the pit often means impeller damage or debris in the pump.
Visible Water Around the Basin Lid
Water or moisture at the seal means it's time for an inspection before it overflows.

Came home to the basement bathroom smelling like a sewer and the little alarm on the wall going off nonstop. They walked me through what a stuck float switch even was, swapped it out, and ran the toilet a dozen times before leaving to make sure it held. No mess, no drama.

Typed "ejector pump repair near me" at 11pm when our laundry room started backing up, and someone actually called back within the hour. Fixed the same day, and the guy even hosed down the pit before he left.

Was sure we'd need a whole new pump after ours started grinding and cutting out at random. Found this crew after searching sewage pump service near me, and it turned out to just need a new check valve and a good clean-out. Been quiet ever since.

I'd been ignoring the musty smell by our basement bathroom for way too long. Looked up basement ejector pump near me and they came out the next morning, showed me the corroded basin before replacing it, and didn't try to upsell anything extra.
