You will know when your OPV has failed, as the silicon pipe feeding back into the water tank will be bubbling constantly. A simple plumbing job and you will have it fixed with this part. You will also need 2 x copper washers 36240007 to seal your new over pressure valve, we will include these for you in this kit

incredible personal service from Ciaran, his time and advice were invaluable when choosing my new machine. Delivered very quickly as well. I can't recommend Ciaran and his company highly enough.
