Cartridge repairs
- Most single-handle shower valves have a pressure-balance cartridge. When it wears or scales up, the water drips, the temperature swings or the handle stiffens. Trim off, cartridge out, and the matching brand cartridge goes in. A temperature limit stop is reset so the water cannot reach scalding.
- Some older two-handle and three-handle valves use compression stems. Those get new washers, seats and packing.
When the valve has to go
- If parts are no longer available, the valve body is cracked, or you want to change the trim style, the valve body behind the wall needs replacing. That usually means opening the wall from behind, often from a closet or adjacent room, or removing tile from the front.
- We work out the least damaging access point. If it has to be from the tile side, we can install a larger trim plate to cover the opening.
Signs you need this
- The showerhead drips after it is turned off
- Water turns hot or cold when someone flushes
- A handle that drags or free-spins
- Low flow only in one shower
- Water stains behind the shower wall
Opened shower walls
- If the tile is coming off for a renovation, replace the valve while access is free, add shut-offs, and look at the drain and the waterproofing. New valves must be pressure-balanced or thermostatic, which is the safer choice for households with children or older adults.
- We pressure-test the new valve before the wall is closed and leave it accessible for the tile setter.
How the job runs
- 1
Trim is removed and the valve brand and cartridge type are identified.
- 2
The cartridge or stem is replaced and the limit stop is set.
- 3
If the body has failed, access is planned and the valve is replaced.
- 4
The shower is tested hot and cold, and with a toilet flushing nearby.
Richmond Hill note: most houses here sit on York Region municipal water with fairly hard supply, and many basements have a floor drain tied to the sanitary lateral. Mention both on the phone; it changes what goes on the truck.
