The Vaillant Turbomax Plus/Turbomax Pro Brass Aqua Sensor 194819 is a brand new, genuine Vaillant spare part with a Vaillant manufacturer's guarantee. The flow switch is an essential component to both Domestic Hot Water and Heating systems as it acts as a safety device that ensures the appliances burner cannot ignite when the system is either low or empty of water. This component triggers when the pump activates to feed the instruction back to the PCB to allow for the ignition sequence to commence.
