Concealed Thermostatic Mixer Valve

With BAI Thermostatic Mixers you will be able to maintain an exact water temperature for the duration of your shower. It protects you from any sudden changes in the water supply to the shower, so even if somebody flushes the toilet or turns on the kitchen faucet the temperature of your shower will remain the same. The thermostatic valve mixes the hot and cold water to your pre-selected temperature and reacts instantly to any changes in the pressure or temperature of the water supply by re-adjusting the mix of hot and cold water. Should there be a failure in your cold water supply, the thermostatic valve will automatically shut down. It is very convenient, it will maintain your pre-selected water temperature, leaving you to relax and enjoy your shower. Compatible with all BAI Shower Heads, Body Sprays and Spouts.

This valve controls only the temperature, it is not an ON/OFF valve!
