Shower valve symptoms
- Temperature swings during use
- A drip from the shower head after the handle is off
- Not enough hot water even though the heater is fine
- A handle that is loose, stiff or turns too far
Repair options
Pressure-balancing valves keep temperature steady when pressure changes. When their cartridge wears, the balance fails. Replacing the cartridge through the trim opening usually fixes it. Older two- or three-handle valves use stems and washers that can be rebuilt. If the valve body itself is failing, replacement is possible with an access panel from behind or a careful tile cut.
- Identify the valve brand and model.
- Shut off water and remove the trim.
- Replace or rebuild the cartridge or stems.
- Adjust the temperature limit stop and test.
Hot water safety
Ontario plumbing rules limit how hot water can be at a shower. If your shower runs very hot, an adjustment of the limit stop is a quick safety fix, especially with children or older adults at home.

Questions we get
Why does my shower get cold when someone uses water?
A worn pressure-balancing cartridge or no balancing valve at all. A new cartridge often solves it.
