This apparatus is to retrofit an existing, non pressure balanced mixing valve to provide pressure balanced operation. The apparatus includes a diverter which leads hot and cold water out of the existing valve body to a pressure balanced mixing valve. The mixed blended water from the pressure balanced mixing valve is returned to the diverter which directs the blended water to the existing outlet(s) in the existing valve body.
