Shower Valve Repair & Replacement in Toronto

Signs you need shower valve repair

• Drips keep falling from the head after you shut the handle
• Temperature jumps hot or cold the moment a toilet is flushed
• A handle that is stiff, loose or spins without changing temperature
• Weak flow at the shower but good pressure at the sink
• Water stains on the ceiling below that appear only when the shower runs

What causes it in older Toronto homes

Older two- and three-handle valves have rubber washers and brass seats that wear. Single-handle valves use cartridges that scale up in Toronto’s hard water. Older valves often lack pressure balancing, which is why a flush upstairs sends a scalding burst. In some older bathrooms, the valve is fed by corroded galvanized pipe that restricts flow.

What we do on site, in order

1. We identify the valve brand and model from the trim, since parts are specific.
2. We shut off water, remove the trim and replace the cartridge, washers or seats as needed.
3. If the valve body is failing or obsolete, we replace it, ideally through the wall behind it from a closet or with a small access panel.
4. We set the hot-limit stop so the shower cannot scald, test and reassemble the trim.

What affects the price

Swapping a cartridge is a small job. Replacing the whole valve depends on how we can reach it: from behind, through an access panel, or through the tile. We tell you which approach your wall allows and price it before starting.

When to call right away

If the valve will not shut off, close the main water supply and call. Water running continuously in a shower is wasteful and can also overflow if the drain is slow.

The job, in four moves

1. 1
   Empty the cabinet

   Shut-off stops tested first; seized ones noted for replacement.

2. 2
   Strip the old parts

   Supply lines, trap and tailpiece off; cartridge or stem pulled.

3. 3
   Fit new hardware

   New cartridge, stops or tap set, slip-joint washers renewed.

4. 4
   Run it hard

   Both temperatures at full flow, every joint wiped and checked dry.
