Running Toilet Repair — Flapper, Fill Valve & Tank Components
A running bathroom plumbing Mississauga wastes 100 to 500 litres of water daily, adding $40 to $200 monthly to your Peel Region water bill. The two most common causes are a failed flapper — the rubber seal at the tank bottom that leaks continuously into the bowl — and a failed fill valve that cannot stop water intake when the tank is full. Both are same-visit repairs completed in 30 to 45 minutes.
Tank component repair also covers flush valve seat resurfacing, residential plumbing Mississauga, supply line replacement, and shut-off valve replacement. Supply lines over 10 years old represent a high risk for under-floor water damage — we inspect supply line condition on every toilet call and replace when age or condition warrants. Seized gate valve shut-off valves are replaced with modern quarter-turn ball valves that provide reliable positive shut-off.
Toilet Leaks — Base, Tank & Supply Lines Mississauga
A toilet leaking at the base after flushing indicates a bathroom sink plumbing Mississauga — the seal between the toilet horn and drain flange. A failed ring allows wastewater into the subfloor cavity with each flush, causing structural damage and mould growth that may not be visible for months. Wax ring replacement requires removing the toilet, replacing the ring and inspecting the flange, and reinstalling — completed in 60 to 90 minutes.
Bathtub plumbing Mississauga — water dripping down the outside of the tank — are caused by a failed tank-to-bowl gasket, loose tank bolts, or a cracked tank. We diagnose the source accurately before recommending a repair. A cracked tank requires toilet replacement; a failed gasket is a same-visit repair. All toilet leak diagnosis is included in the flat-rate service call — no separate diagnosis charge.

Flapper and Fill Valve Diagnosis
Diagnosing a emergency plumbing Mississauga in Mississauga begins with isolating the cause between the flapper and the fill valve. We perform a dye test — placing food colouring in the tank and waiting without flushing — to confirm flapper leakage into the bowl. Fill valve failure is confirmed by observing the fill valve continuing to run after the tank reaches the water line, or by water overflowing into the overflow tube.
Wax Ring Selection and Flange Inspection
Wax ring selection for toilet replacement in Mississauga depends on the drain services Mississauga relative to the finished floor. A standard wax ring is correct when the flange is at floor level. A thick or double-stack wax ring is required when the flange sits below the finished floor surface — common in Mississauga bathrooms where tile has been installed over the original floor without adjusting the flange height.
