Abstract
There is described a mixer tap with integrated thermostatic mixing valve (TMV). The tap comprises in a single housing: hot and cold water inlets; an outlet for mixed water; hot and cold lever controls and a thermostatic mixing device within the single housing to prevent water above a certain temperature being emitted from the common outlet. The cold water control opens a fluid path from the cold inlet to the common outlet, bypassing said thermostatic mixing device, allowing better assurance of purity. The thermostatic mixing device and strainer/check valve cartridges are housed in an internal body so as to be readily accessible for servicing after installation of the device by removing only a cap part of the housing.
