What we run into most

Frequent Pipe & Fixture Problems We Resolve

We've handled every type of below-grade plumbing issue. Here are the problems homeowners call us about most often.
🚿

Floor Drain Backing Up

A backing-up floor drain usually signals a blockage or corrosion further down the line rather than an issue at the drain itself. Left unaddressed, this risks water damage during the next heavy rain or laundry cycle. We trace the line and clear or repair the actual source.

⚑

Sewage Ejector Pump Not Working

A failed ejector pump means basement fixtures below the sewer line can no longer drain at all. This creates an immediate, unusable bathroom or laundry situation. We diagnose whether the issue is electrical, mechanical, or a failed check valve and repair or replace accordingly.

πŸ”Š

Gurgling Sounds From Basement Drains

Gurgling usually means air is being displaced by a partial blockage or a dried-out trap seal somewhere in the system. Ignoring it often leads to a full backup later. We inspect the drain and vent system to identify the actual cause.

😀

Persistent Sewage Odor in the Basement

A lingering sewage smell without an obvious leak often means a dried-out floor drain trap or a cracked vent pipe letting sewer gas escape. Left unresolved, this affects indoor air quality throughout the home. We locate the exact source and reseal or repair it.

πŸ”§

Old Cast Iron Pipe Corroding

Cast iron drain pipes corrode from the inside over decades, gradually narrowing the interior and causing increasingly frequent backups. Waiting too long risks a full pipe failure. We assess the pipe's condition with camera inspection and recommend repair or replacement.

πŸ“

Basement Renovation Needs Plumbing Planned

Fitting plumbing around an already-framed basement layout compromises drain slope and pipe sizing. This mistake is expensive to correct once walls are closed. We finalize the plumbing plan before framing begins and coordinate directly with other trades.

🌧️

Water Backing Up Through Floor Drain in Heavy Rain

Water entering through a floor drain during storms usually points to a municipal sewer system overload without a backwater valve to stop it. This risk repeats with every significant rainfall. We install a backwater valve to prevent future backups.

πŸ’§

Low Water Pressure From Old Supply Lines

Galvanized steel supply pipes corrode internally over time, gradually restricting water flow and reducing pressure throughout the home. This decline often happens slowly enough to go unnoticed until it becomes significant. We assess and replace corroded sections as needed.

πŸ—ΊοΈ

Unsure What Plumbing Is in the Basement

Many homeowners are unaware of floor drains, cleanouts, or backwater valves beyond the fixtures they actively use. This gap in knowledge means problems can develop unnoticed for years. We map the full basement plumbing layout during a thorough assessment.

Found our sump pump wired wrong by a previous plumber

Core Ontario Plumbing Services came out for a gurgling floor drain and ended up catching that our ejector pump had been installed without a proper check valve years ago. Fixed it the same visit and explained exactly why it mattered.

Camera inspection saved us from guessing

Our basement floor drain kept backing up and we were about to just replace the whole line. The camera inspection showed the cast iron pipe was actually fine except for one section, so we only had to fix that spot instead of the whole run.

Good service, took a bit longer due to old pipe

Our basement has original galvanized pipe from the 1960s and the repair took longer than the initial estimate because of how brittle the fittings were. The plumber was upfront about it and the final result works great.

Coordinated perfectly with our renovation contractor

We were mid-renovation and needed the plumbing plan finalized before framing continued. The team at Core Ontario Plumbing Services came out quickly and worked directly with our contractor so nothing had to be redone later.

Checked everything, not just what we called about

We called about a slow floor drain but the technician also checked our sump pump and backwater valve while he was there. Turned out the sump pump float was starting to stick, which we would not have known otherwise.

Honest about what actually needed fixing

I expected to be told we needed a full drain line replacement, but Core Ontario Plumbing Services explained our cast iron pipe still had years of life left with a minor repair. Appreciated not being upsold on something we did not need yet.
