PLEASE NOTE:
If the outlet TCO switch that is attached to the outlet pipe is the problem then you will need to order part number 85000140 and just remove the TCO and fit it to your old pipe which will give you a working shower again. The pipe that comes under the new part number that you remove the TCO from is much smaller than your old pipe and this means it will be of use to you.
NO WIRES OR TERMINALS COME WITHN THE OUTLET TCO AND IF NEEDED WILL NEED TO BE SOURCED ELSWHERE.
