What we run into most

Real-World Plumbing Issues We Repair Fast

We've seen every issue a bathroom plumbing system can develop. Here are the problems our clients call us about most often.
🚽

Toilet Keeps Running After Flush

A worn flapper valve or a fill valve that no longer seals correctly lets water run continuously from tank to bowl. Left unaddressed, this can waste thousands of gallons a month and drive up the water bill. We rebuild or replace the internal components so the toilet shuts off properly.

🚰

Slow or Clogged Bathroom Sink Drain

Hair, soap scum, and toothpaste residue build up gradually inside drains until water barely moves through. Left too long, the clog worsens and can affect connected fixtures. We clear the blockage with mechanical snaking or hydro jetting, without the pipe damage chemical cleaners can cause.

🚿

Low Water Pressure in the Shower

Weak pressure usually comes from a clogged aerator or showerhead, or from corrosion further upstream in older pipe material. Left unresolved, corroded pipe continues narrowing from the inside with no outward warning. We trace the actual cause rather than just cleaning the fixture and hoping it holds.

👃

Persistent Bad Smell From the Drain

A dried-out P-trap stops blocking sewer gas, letting odors into the bathroom even after cleaning. Left unaddressed, a trap that keeps drying out points to a deeper venting issue. We diagnose whether the fix is as simple as refilling the trap or requires repairing the vent system.

💧

Leaking Faucet That Won't Stop Dripping

A worn washer, O-ring, or cartridge lets water drip steadily even when the faucet is fully off. Left alone, the leak wastes water continuously and can indicate the fixture is nearing the end of its service life. We identify the exact part causing the leak and replace it correctly.

⚠️

Water Pooling Around the Toilet Base

Standing water at the base of a toilet usually means a failed wax ring seal or a cracked component allowing water to escape during flushing. Left unchecked, this can damage subfloor material beneath the toilet. We reseal or replace the affected parts to stop the leak at its source.

🔊

Gurgling Sounds From Bathroom Drains

Gurgling noises when other fixtures are used usually signal a venting or drain line issue rather than a simple clog. Left ignored, this pattern often develops into slow drainage across multiple fixtures at once. We inspect the full drain and vent system to find the actual restriction.

🔧

Corroded Supply Lines Under the Sink

Supply lines under constant water pressure can corrode over time, especially in older homes with original plumbing. Left unnoticed, a failing line can release water quickly rather than gradually. We check these connections during every visit and replace lines showing early wear.

💰

Rising Water Bill With No Clear Cause

An unexplained increase in the water bill often traces back to a hidden leak or a running toilet that hasn't been noticed yet. Left unaddressed, the cost keeps climbing month after month. We check every fixture and connection to find exactly where the waste is coming from.

Rachel B.

Finally fixed our running toilet for good

We had replaced the flapper ourselves twice and it kept running. The technician found the fill valve was actually the problem and rebuilt the whole tank assembly. No issues since.

Traced our pressure issue to old pipes

Core Ontario Plumbing Services figured out our low pressure was from corroded galvanized pipe, not the showerhead like we assumed. They walked us through the options without any pressure to do the biggest fix right away.

Good service, appointment ran a bit long

The drain clearing took longer than expected because of how built up it was, but the technician kept us updated and the drain has worked perfectly since. Would book again.

Found the source of a smell we couldn't figure out

We had a bathroom smell for months and assumed it was just old plumbing. Core Ontario Plumbing Services found a dry P-trap under a rarely used sink and fixed it in minutes. Wish we had called sooner.

Thorough inspection, not just a quick patch

The technician checked every fixture in the bathroom, not just the faucet I called about, and caught a supply line starting to corrode before it became a problem. Really appreciated the full look.

Omar H.

Honest about what actually needed fixing

I expected to be told I needed a full toilet replacement but the technician explained a rebuild would work just as well and cost less. Core Ontario Plumbing Services earned a repeat customer with that honesty.
