have just purchased a diverter valve diaghragm repair kit for my wicks 3 way valve.
Can anyone tell me how to replace it. I know to turn off all electrics & stop the water filler in loft
Do i need to drain all the top underfloor pipes so the valve has no water in it.
Do I need to remove the 3 way valve completely out off the pipes to do the repairs.

you only need to change motor on valve body ,lock valve from slider and hook it so does not slide back remove two screw ,make Electrical connection ,if you want to change whole body than drain system ,stop water in let to header tank,open when finish air vent all radiators,turn off power supply to boiler before start
