Why your shower valve matters
- Regulates water temperature and flow

- Ensures steady water pressure for a comfortable shower
When this part begins to fail, the consequences are immediate—and often frustrating.
5 warning signs of a failing shower valve
- Temperature fluctuations – Water shifts from cold to hot suddenly, especially when another faucet is used.
- Persistent dripping – Even when the shower is turned off, you hear a drip.
- Low water pressure – Mineral buildup or internal blockages reduce flow.
- Stiff or loose handle – The knob becomes hard to move or won’t stay in place.

If you notice one or more of these issues, it’s usually time to consider a full replacement.
