A mixing valve is a plumbing component that blends hot and cold water to a desired temperature before it reaches a faucet or shower. These valves help prevent scalding by limiting maximum hot water temperature and provide consistent comfort. They are important in homes and critical in commercial settings like hospitals and schools where precise temperature control is required. Mixing valves also support energy efficiency by allowing higher storage temperatures while delivering safe temperatures at fixtures.

Mixing valves blend hot and cold water for safe delivery.
A family installs a mixing valve to prevent scalding in showers, ensuring water temperature stays within a safe range even when the tap is turned fully hot.
Check and maintain your mixing valve regularly. Mineral buildup can affect performance, and professional calibration may be needed for accurate temperature control.
“Check and maintain your mixing valve regularly. Mineral buildup can affect performance, and professional calibration may be needed for accurate temperature control.”
Mixing valves are increasingly required by plumbing codes to prevent scalding injuries.
Do I need a mixing valve at my water heater?
Many homes benefit from one, especially with higher storage temps or households with children.
Can a mixing valve fail?
Yes. Mineral buildup or wear can cause temperature drift, so regular inspection helps.
Is a mixing valve the same as an anti-scald valve?
They are related. A mixing valve blends hot and cold water, while anti-scald valves limit maximum temperature at fixtures.
