In some states, local plumbing codes require a TCV in showers and bathtubs, also in any commercial application. When the code does not require the TCV, please consider the fill time. TCV fill time is 7-8 GPM (gallons per minute) while fast fill deck mount bathtub faucets fill time range from 12 up to 18GPM. Lastly, the flow rate can be affected by size of supply lines or in-house water pressure. If possible install 3/4″ water lines vs 1/2″. When you choose TCV please consider your local water quality. The TCV cartridge’s is sensitive, and most likely will clog, and will need to removed and cleaned due to hard water with calcium and iron. Therefore the warranty for TCV is only 1 year. There are a variety of other TCV’s available in the market which can be installed into the hot water supply line. Please consult with experienced professional licensed plumber to avoid any issues down the road.
WHAT IS A THERMOSTATIC CONTROL VALVE?
The purpose of a Thermostatic Control Valve (TCV) is to regulate the temperature of water before it reaches your sink or bathtub faucet. A TCV ensures constant temperature of water by blending hot water with cold water to prevent scalding or thermal shock. There are circumstances where inlet temperature and pressure are inconsistent and pose potential danger to a bather. Responding to these variations in temperature and pressure is the only way to ensure maximum bather safety. The Ella has it’s own deck mount unique 5pc TCV faucet.
