The RAK 15mm Thermostatic Mixing Valve is a compact, practical safety valve that helps protect against scalding by limiting the temperature of hot water reaching a tap, shower or bath. Its round, brass body is designed to be fitted within the supply pipework, so it works quietly in the background once installed.

A thermostatic mixing valve, often called a TMV, blends hot and cold water to a safe, steady temperature before it reaches the outlet. They're widely specified in care homes, schools and healthcare settings, and they're increasingly popular at home too. It's a sensible choice for children's bathrooms and homes with older or less mobile family members.

It should be installed and commissioned by a qualified plumber familiar with the relevant standards. Regular servicing, including cleaning the internal strainers, keeps it working as it should. It's a small investment that adds real peace of mind.

It comes with a 15 year guarantee, giving you lasting reassurance. It's a dependable choice for any home where safety at the tap matters.
