Signs You Need Toilet Repair
- The toilet runs continuously or cycles on periodically
- Handle needs to be held or jiggled to complete a flush
- Water pools around the base after flushing
- The bowl rocks slightly when pressure is applied to the seat
- Flush strength has weakened noticeably over time
- A faint odour is present near the floor around the toilet
Internal tank component wear
Fill valves and flappers are the parts most likely to fail first, since they're in constant contact with water and subject to mineral buildup from Toronto's moderately hard water supply. A flapper that no longer seals lets water trickle from tank to bowl, which shows up as a toilet that intermittently refills itself with no one using it.
Fill valves can also fail to shut off completely, running water into the overflow tube. We test both components independently by observing water levels and listening for the fill valve after a flush, since a worn flapper and a misadjusted fill valve produce similar symptoms but need different fixes.
Base seals and flooring
Water pooling at the base often traces to a failed wax ring, particularly in older homes where the toilet has been removed and reset at some point, or where the subfloor has shifted slightly with age. A rocking toilet accelerates wear on that seal because every movement flexes the connection between the flange and the bowl.
On upper floors and in condominium units near Yonge and Sheppard, a loose base is worth addressing quickly, since a failed seal there risks water tracking into the ceiling of the unit below rather than just the local floor.
Repair versus replacement
Most running and weak-flush complaints are resolved by replacing the fill valve, flapper, or both, along with the supply line washer if it shows wear. A rocking or leaking base calls for lifting the toilet, replacing the wax ring, and checking that the flange itself is sound and level before resetting the fixture.
Where the flange has corroded or sits below finished floor height after a flooring upgrade, a flange extender or repair kit addresses that gap so the new seal isn't asked to bridge more distance than it's designed for.
Supply line and shutoff condition
The small shutoff valve feeding a toilet is easy to overlook until it's needed, and in older Willowdale and Downsview homes those valves can seize partially closed or develop a slow weep at the packing nut after years without being turned. While repairing the tank internals or the base seal, we check that this shutoff still operates freely, since a valve that won't close fully complicates any future repair and one that drips adds its own slow source of moisture near the floor.
The braided or vinyl supply line connecting the shutoff to the tank is a similarly overlooked part, and a line that's kinked, corroded at the fittings, or original to a decades-old installation is worth replacing while the toilet is already being serviced rather than waiting for it to fail on its own.
Older tank hardware, including the flush lever arm and the chain or strap connecting it to the flapper, is also worth a look during a repair visit, since a chain with too much slack or one that's caught under the flapper produces symptoms that can look like a flapper problem even when the flapper itself is fine.
How We Handle It
- 1
Observe the symptom
We watch the tank refill cycle and check water levels to isolate whether the fill valve or flapper is at fault.
- 2
Inspect the base
The toilet is checked for rocking and the floor around it for signs of past or active leaking.
- 3
Replace worn internals
Fill valve, flapper, or supply line components are swapped as needed based on what's failing.
- 4
Reset the wax ring if required
When the base seal is compromised, the toilet is lifted, the old wax ring removed, and a new seal set against a sound flange.
- 5
Confirm stability and flush performance
We check the reset toilet for rocking and run several flushes to confirm normal fill and drain behaviour.

Why does my toilet keep running after the tank fills?
This is most often a flapper that no longer seats properly or a fill valve that hasn't fully shut off, both of which are common wear points as the rubber and internal seals age. We test each component to identify which one is letting water pass.
Is water around the base always a wax ring problem?
Not always, since condensation on the tank in humid weather can also collect at the floor. We check whether the water appears during or shortly after a flush, which points to the base seal, versus gradually over time, which points more toward condensation or a supply line connection.
Can a toilet be repaired instead of replaced?
In most cases, yes. Internal components like fill valves, flappers, and wax rings are replaceable parts, and repairing them restores normal function without needing a new fixture, provided the bowl and tank themselves aren't cracked.
Why does my flush feel weaker than it used to?
Weak flushing can stem from mineral scale partially blocking the small rim jets under the bowl lip, or from a fill valve that isn't delivering full tank volume before the flush. We check both the rim jets and the fill level to find the cause.
