What we run into most

Frequent Pipe & Fixture Problems We Resolve

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

Toilet Keeps Running After Flush

A worn flapper valve is the most common cause, letting water trickle continuously from the tank into the bowl. Left alone, this can waste hundreds of litres a day and quietly inflate the water bill. We diagnose whether the flapper, fill valve, or both need replacing.

💧

Water Pooling Around the Base

This almost always points to a failed wax ring, the seal connecting the toilet to the floor drain. Left unaddressed, the leak seeps into the subfloor and can lead to soft flooring or hidden mold. We pull the toilet, replace the wax ring, and check the flange for damage.

🔧

Toilet Wobbles When You Sit Down

A rocking toilet usually means the flange has cracked, corroded, or pulled loose from the subfloor rather than a problem with the toilet itself. Left ignored, the wobble stresses the wax ring and often causes a base leak within weeks. We repair or replace the flange and reset the toilet properly.

🌀

Weak or Incomplete Flush

Needing two or three flushes to clear the bowl usually traces back to clogged rim jets, a low water level, or an aging flush valve. Ignoring it just means living with an inconvenient toilet every single day. We check all three causes together to fix it correctly the first time.

⚠️

Cracked Toilet Tank or Bowl

A hairline crack in porcelain will not stay hairline, since the material does not flex and stress spreads over time. A sudden failure can flood the bathroom without warning. We replace the affected component, and sometimes just the tank if the bowl is still intact.

🔊

Toilet Won't Stop Hissing

A hissing sound between flushes usually points to a fill valve that never fully shuts off, refilling the tank more often than it should. Left alone, this steadily wastes water even when nobody has used the bathroom. We replace the fill valve and confirm the tank holds properly afterward.

🕐

Slow Tank Refill After Flushing

A slow refill often means a partially blocked or failing fill valve that cannot deliver water at the normal rate. This leaves a bathroom without a usable toilet for several minutes at a time. We test the valve and water pressure to confirm the exact cause before replacing parts.

🔁

Toilet Repeatedly Needs the Same Repair

A toilet that keeps needing the same fix usually has an underlying flange or alignment issue that a surface-level repair never resolved. Continuing to patch it eventually costs more than addressing the real cause. We inspect the full base and flange rather than repeating the same quick fix.

🏚️

Old Toilet With No Replacement Parts Available

Older toilets from discontinued brands can leave a homeowner unable to find matching parts for a routine repair. This often stalls a simple fix for days while parts are sourced. We stock a wide range of universal components and adapt the fit for older or non-standard toilets.

Karen D.

Found the real cause of our running toilet

We had replaced the flapper ourselves twice and it kept running anyway. The technician from Core Ontario Plumbing Services checked the fill valve and found that was the actual problem. Fixed in under 40 minutes and it has been silent ever since.

Caught the leak before it hit the subfloor

There was a small amount of water around the base that I almost ignored. Glad I called when I did because the wax ring had already failed. They replaced it and checked the flange while they were in there. No damage to the floor at all.

Good repair, had to wait a day for the part

Our toilet is older and the original flush valve was discontinued, so they needed a universal replacement part that took an extra day to arrive. The fix itself was quick once the part showed up and the price stayed exactly what was quoted.

Honest about repair versus replace

I expected to be told I needed a whole new toilet. Instead the technician from Core Ontario Plumbing Services explained our unit was only 8 years old and just needed a new flapper and fill valve. Saved us a lot of money and the toilet works perfectly now.

Fixed a wobble we had lived with for months

Our toilet had rocked slightly every time someone sat down and we just got used to it. The technician found the flange had cracked and repaired it properly. It has not moved an inch since, and I wish we had called sooner.

Weak flush finally diagnosed correctly

Our toilet needed two or three flushes every time and I assumed it was just old. Core Ontario Plumbing Services checked the rim jets, the water level, and the flush valve and found mineral buildup was the culprit. One visit and it flushes like new now.
