Why St. Catharines chooses Ottr Plumr
The Garden City's go-to plumbing and heating crew — from Port Dalhousie waterfront homes to downtown businesses, we keep things flowing.
Niagara weather doesn't mess around. One spring storm, one summer downpour, or one fast snowmelt event is all it takes to flood a basement — and the cost of water damage (drywall, flooring, contents, mould remediation) dwarfs the cost of a properly-installed sump pump and battery backup system by an order of magnitude.
Ottr Plumr installs, replaces, and services sump pumps and battery backup units for homes across the region — from low-lying neighbourhoods near the canal in Welland to lakeside properties in Crystal Beach and Port Dalhousie where the water table is genuinely no joke. We test and tune existing systems annually, and we'll spec the right pump for your basement size, water table, and risk level — not the cheapest pump on the shelf.
Most basement floods we see are entirely preventable. The pump was undersized, the discharge line was frozen or pitched wrong, the float switch had jammed, or — most often — the power went out during exactly the storm that needed the pump. A battery backup system is the single best insurance policy a Niagara homeowner can buy.
And yes, we'll install a water alarm with a Wi-Fi sensor too, so your phone buzzes the second water touches the pit — even if you're at the cottage or on vacation.
We service every corner of St. Catharines — including Port Dalhousie, Downtown, Glenridge, Western Hill, Merritton, Grantham, and Facer — usually same-day for sump pumps calls.
What's included
Sump Pumps specialties for St. Catharines
Battery Backup Systems
Backup pumps that keep working when the power goes out — exactly when you need them most. Storms cause both flooding and outages, and your primary pump is useless without electricity.
Discharge Line Service
Frozen, clogged, or wrongly-pitched discharge lines repaired or rerouted, with proper freeze-resistant terminations for Niagara winters.
Annual Testing
Pre-spring testing, pit cleaning, and float verification to make sure your pump is ready before storm season actually hits.
Sewage Ejector Pumps
Ejector pump install and service for basement bathrooms, laundry, and below-grade fixtures.
Water Alarms
Wi-Fi-enabled water sensors that ping your phone the moment water touches the pit, giving you a real chance to act before damage spreads.

FAQs
Sump Pumps in St. Catharines — common questions
Do you offer sump pumps in St. Catharines?
Yes — Ottr Plumr provides sump pumps throughout St. Catharines and the surrounding Niagara Region, with same-day appointments and 24/7 emergency response.
How fast can a plumber get to St. Catharines?
From our Welland shop we typically reach St. Catharines the same day for non-emergencies and within the hour for true emergencies. Call 289-488-1007 to dispatch.
Do I need a battery backup sump pump?
If your basement is finished, you have a sewage ejector pump, or you store anything valuable down there — yes. The biggest storms are exactly the ones that knock out power, and your primary pump is just an expensive paperweight without electricity. Backup systems pay for themselves the first time they save you.
How often should a sump pump be replaced?
Most sump pumps last 7–10 years. We recommend planned replacement at the 10-year mark even if it's still running — the cost of a planned swap is a small fraction of the cost of cleanup after a failure during a storm.
How do I know if my sump pump is working?
Pour a 5-gallon bucket of water slowly into the pit. The pump should kick on, drain it, and shut off cleanly without short-cycling. If it hesitates, runs rough, or doesn't shut off cleanly — call us before the next storm, not after.
Why does my sump pump run constantly?
Usually one of three things: a stuck float switch, a high water table after heavy rain, or a broken/missing check valve causing water to flow back into the pit. A short diagnostic visit tells us which.
Can the discharge line freeze in winter?
Yes — and it's a common cause of mid-winter basement floods in Niagara. We use freeze-resistant terminations, proper pitch, and discharge points placed where snow won't pile up against them.
