Sewage Pump Repair in Scarborough: When Gravity Can't Do the Job

Most of a house drains by gravity. But a bathroom in a finished basement, a laundry room below the sewer line, or a basement apartment in a Malvern or Agincourt townhouse sits lower than the pipe leaving the house — so a pump has to lift the wastewater up to it. When that pump fails, every fixture below grade stops, and the sealed pit under the floor starts filling with sewage. That's the call we take 24/7.

ASAP Scarborough Plumbing Services provides sewage pump repair Scarborough wide — ejector pumps, grinder pumps, and septic effluent pumps — plus same-day sewage pump replacement, alarm and float repair, and ejector pit cleaning. These are not the same as a sump pump, which moves clean groundwater from an open pit; a sewage pump handles waste in a sealed, vented basin, and it takes a licensed plumber who works on them every week.

Sewage pump not working, or the alarm won't stop? Call (437) 475-2458 — we're usually at a Scarborough home within the hour, with replacement pumps on the truck.

Three Pumps, One Job — and Where Each One Lives

The repair is similar; the pump and the setup aren't. Knowing which one you have tells us what to bring.

  • Sewage Ejector Pump — the basement bathroom:

    Sits in a sealed basin under the basement floor and lifts waste from a below-grade toilet, shower, or laundry up to the main drain. Passes solids up to about 2 inches whole. The most common sewage ejector pump repair Scarborough homeowners call for.

  • Grinder Pump — the long or pressurized line:

    Shreds waste into a slurry and pushes it at high pressure through a small-diameter force main. Used when the sewer connection is far away, uphill, or on a pressure sewer system. Grinder pump repair and grinder pump replacement need the right cutter assembly and a pressure-rated check valve.

  • Septic Effluent Pump — the pump chamber:

    On the few Scarborough-area properties still on septic, this pump moves treated liquid from the tank's pump chamber to a raised drain field. Septic pump repair and septic pump replacement follow the same logic — float, check valve, alarm — in a different box.

Sewage Pump Alarm Going Off? Do This First

The high-level alarm means the basin is nearly full and the pump hasn't emptied it. You have a little time — not much. In order:

  • 1

    Stop using water below grade — and go easy upstairs. Every flush, shower, or laundry load in the basement goes straight into the basin. Hold off until the pump is running again.

  • 2

    Check the breaker and the plug. A tripped breaker or GFCI is the most common reason a sewage pump is not working. Reset it once. If it trips again, leave it off — that's a shorted motor or wiring, and it's our job.

  • 3

    Listen for the pump. Humming but not pumping means a jammed impeller or a stuck check valve. Silence with power on means a float switch that's hung up or a dead motor. Either way, don't open the sealed lid yourself — the basin holds raw sewage and sewer gas.

  • 4

    Silence the alarm, then call. Most panels have a silence button; the light stays on. Call (437) 475-2458 and tell us it's a sewage pump alarm — it's dispatched as an emergency.

Sewage Pump Repair & Replacement in Scarborough

We fix what's worth fixing and tell you when it isn't. On a pump under about seven years old, most faults are a single part; past ten, replacement is usually the better spend.

Float Switch & Alarm Repair

Floats tangled on the discharge pipe, pinned against the basin wall, or simply worn out are the top cause of a pump that won't start — or won't stop. We replace floats, tethers, and alarm sensors and set them so they can't hang up again.

Check Valve, Discharge & Vent

A failed check valve lets the whole column fall back and the pump short-cycles itself to death. We replace it, clear a blocked or frozen force main, and make sure the vent is doing its job so the basin can breathe and the house doesn't smell.

Jammed or Burnt-Out Pump

"Flushable" wipes, hygiene products, and rags are what jam an ejector or strip a grinder's cutters. We clear the impeller or cutter assembly where the pump is sound, and carry replacement sewage pumps on the truck when it isn't — same-day sewage pump replacement for standard basins.

Sewage Lift Pump & New Installations

Adding a basement bathroom or suite? We install the complete sewage lift pump system — basin, pump, sealed and vented lid, check valve, and alarm — to code, so the City inspection passes and the suite stays dry.

Sewage Ejector Pit & Basin Cleaning

A sewage basin is not a self-cleaning tank. Grease, soap scum, grit, and solids settle below the pump's intake and build into a layer of sludge the pump never moves. Over a few years that layer buries the float, coats the sensors, and eats into the pump's run time — until one day the alarm goes off for no reason you can see, or the whole basement smells like a sewer.

Sewage ejector pit cleaning removes that layer properly: we isolate the pump, pump out and vacuum the basin, scrape and flush the walls and floor, inspect the pump base, float, check valve, and lid gasket, then refill and test a full cycle. Most homes with a basement bathroom in daily use are due every two to three years; a basement apartment, sooner.

  • Odour in the basement that comes and goes — sludge off-gassing, or a lid gasket that's failed.
  • Pump runs longer than it used to — the intake is partly buried.
  • Alarm trips with no obvious fault — the float is dragging through sediment.

Sewage basin cleaning is the cheapest service on this page and the one that prevents most of the others. Book it with your annual plumbing check.

How We Handle a Sewage Pump Call

From alarm to a tested, running pump — usually in one visit, anywhere in Scarborough.

Diagnose Without Guessing

Power, float, check valve, discharge, and the pump itself — tested in order, so a $60 float isn't quoted as a $1,500 pump.

Repair or Replace, Priced Side by Side

You see both numbers before we touch anything. Replacement pumps for standard 18- and 24-inch basins are on the truck.

Seal, Vent, Test, Clean Up

New lid gasket, vent checked, three full cycles run with the alarm tested — and the area sanitized before we leave.

Serving Agincourt, Malvern, Wexford, Clairlea, Guildwood, Cliffside, West Hill, Scarborough Village, and every neighbourhood between.

Sewage, Ejector & Grinder Pump Repair in Scarborough — FAQ

What's the difference between a sewage ejector pump and a sump pump?

A sewage ejector pump moves wastewater — from a basement toilet, shower, or laundry — up to the main sewer line from a sealed, vented basin. A sump pump moves clean groundwater from an open pit out to the yard. They look similar in the floor, but they're different pumps, different plumbing, and different health risks; a sewage pump should never be swapped for a sump pump or vice versa.

My sewage pump alarm is going off — is it an emergency?

Yes, a sewage pump alarm is an emergency — it means the basin is near the top and the pump hasn't emptied it, so the next flush can overflow raw sewage onto the floor. Stop using water in the basement, check the breaker once, silence the alarm, and call us. We dispatch alarm calls 24/7 and are usually at a Scarborough home within the hour with a replacement pump on the truck.

Why is my sewage pump not working?

A sewage pump that's not working usually comes down to one of five things: a tripped breaker, a float switch that's stuck or tangled, a jammed impeller (wipes and hygiene products are the usual culprit), a failed check valve letting water fall back, or a burnt-out motor. The first four are repairs; the last is a replacement. We test in that order so you only pay for what's actually broken.

Should I repair or replace my sewage pump?

Repair the sewage pump when it's under about seven years old and the fault is a float, check valve, or a clearable jam. Replace it when the motor has failed, when a grinder's cutters are worn, when it's past ten years, or when it's undersized for a suite that's now in daily use. Sewage pump replacement in Scarborough is usually a same-day job for standard basins; we give you both prices on site.

How often should a sewage ejector pit be cleaned?

A sewage ejector pit should be cleaned every two to three years for a basement bathroom in regular use, and every year or two for a basement apartment or a household that puts a lot through it. Sludge that settles below the intake buries the float, shortens the pump's life, and causes odours and false alarms. Sewage basin cleaning is a short visit and the best way to avoid an emergency call.

Do I need a grinder pump or an ejector pump for a new basement bathroom?

For most Scarborough basement bathrooms you need an ejector pump, not a grinder — the main drain is a few metres away and a little above the floor, which is exactly what an ejector is built for. A grinder pump makes sense when the discharge has to travel a long way, climb more than a storey, or connect to a pressure sewer. We'll look at your layout and tell you which one, and size the basin so it passes inspection.
