Sewage Ejector Pump Installation Vancouver
Basement bathroom below the City sewer line? Below-grade laundry sink? Sewage ejector pump moves waste up to the main lateral so the suite can function below grade.
Zoeller and Liberty ejector pumps. Install, replace, repair. Pit construction. (778) 961-0824.
When You Need a Sewage Ejector Pump in Vancouver
A sewage ejector pump lifts wastewater from below-grade fixtures up to the main sewer lateral. Required for any plumbing fixture that sits below the City sewer service line – common in Vancouver basement suites, finished basements with full bathrooms, and basement laundry rooms in older homes.
Different from a sump pump. Sump pumps move groundwater from a sump pit to discharge. Sewage ejector pumps move actual wastewater (gray water plus black water from toilets) from a sealed pit to the sanitary sewer. Different pump design, different pit sealing, different code requirements.
Common Vancouver applications:
Basement suite. Full bathroom (toilet, sink, shower) plus kitchen plumbing below the main sewer line. Ejector pump in a sealed pit handles all the suite’s wastewater. Permit and inspection required.
Finished basement with full bath. Standard upgrade in 1960s-1980s Vancouver homes that originally had unfinished basements. Adding a basement bathroom requires either gravity drain (if elevation permits) or an ejector pump.
Below-grade laundry. Basement laundry rooms with washer drain below sewer level. Ejector pump or sewage basin tied into the laundry standpipe.
Commercial below-grade fixtures. Restaurant basement washrooms, retail building basement service sinks, parkade attendant washrooms.
We install Zoeller M267 / M53 (1/2 HP residential), Liberty LE51 series, Wayne SPV500 – all sewage-rated cast iron pumps with float switches and sealed sewage pit covers. Installs $2,989-$5,989 typical depending on whether the pit needs construction or already exists.
Pit Construction, Pump Install, Discharge Tie-In
If a sewage pit doesn’t already exist, we excavate one. Standard pit dimensions 24″x36″x36″ for a single-bathroom application. Pit liner is a sealed plastic basin (Stonyhurst or Polylok) – sewage pits require sealed covers to contain sewer gas, different from sump pits which can be open.
Pump install. Cast iron sewage-rated pump sized for the application. 1/2 HP residential, 3/4 HP for higher-volume residential, 1 HP+ for commercial. Float switch positioned for proper cycle timing. Check valve on the discharge line to prevent backflow when pump shuts off.
Discharge tie-in. 2″ (residential) or 3″ (commercial) Schedule 40 PVC discharge line from pump to the sanitary sewer connection point. Air gap or vent connection per BC plumbing code. Must rise to invert elevation above the sewer line, then tie in with a Y-fitting.
Electrical. Dedicated 20-amp circuit with GFCI protection. We coordinate with the electrician or recommend one – some installs include the electrical, some require separate trade.
Permit and inspection. BC plumbing code requires City of Vancouver permit for any new sewage ejector install. Rough-in inspection before backfilling the pit and discharge line, final inspection after install completion. Stamped certificate of work for the property file.
Alarm and backup considerations. Many sewage ejector installs include a high-water alarm (alerts you if the pit is filling without the pump activating). Battery backup pumps available for properties where power loss during use would create immediate sewage overflow. Add $389-$789 for alarm + battery backup.
Replacement & Maintenance
Sewage ejector pumps in residential service last 8-15 years typical. Commercial pumps wear faster from higher use – 5-10 years.
Replacement in existing pit. Drop in new sewage-rated cast iron pump, replace float switch and check valve while we’re in there. $1,289-$2,189 typical for residential 1/2 HP swap.
Annual maintenance. We open the pit cover, inspect the float switch, vacuum sediment from the pit bottom, test the pump cycle with a bucket of water. $169-$249 standalone, or included in drainage maintenance contracts.
Common failures we diagnose:
Pump won’t activate even when pit fills. Failed float switch (most common, $189-$289 replacement), failed pump motor (replace pump $1,289-$2,189), or stuck check valve.
Pump runs constantly. Pit float stuck in the up position, or pump can’t keep up because the discharge is blocked. Diagnose and fix.
Backup into the suite. Check valve failed – pit empties into the basement when the pump shuts off. $329-$489 check valve replacement.
Sewer gas smell. Pit cover seal failed. Replace pit cover gasket and verify the vent connection is properly piped. $189-$289.

9 Sewage Ejector Pump Tips for Vancouver Owners
- Test the pump quarterly. Pour a bucket of water into the pit. Pump should activate within 5 seconds, clear in 30. If lagging, schedule service.
- Don’t flush wipes, even “flushable” ones. Aggregate at the float and discharge fittings, jam the pump.
- Install a high-water alarm. Sewage pit overflow into a finished basement is a $20,000+ disaster. Alarm is $189-$289.
- Battery backup for high-risk properties. Basement suites with full bathrooms, properties with previous overflow history – battery backup is cheap insurance.
- Annual maintenance keeps the float clean. Sediment accumulates and fouls the float switch over time. Annual visit catches issues.
- Get the permit and certificate. BC code requires it. Resale and insurance both ask for documentation.
- Replace at year 10-12 preventively. Sewage pumps slow down over years before failing dramatically. Plan replacement before failure.
- Sewage ejector vs. sump pump – different pumps. Don’t replace a sewage ejector with a converted sump pump. Sewage pumps have sealed motor housings and solids-handling impellers.
- Coordinate with renovation rough-in. Adding a basement bathroom? Plan the sewage ejector during the renovation rough-in, not after.
