I have an Office Lever Plus that is about a year old. I see that the WLL has created a copper washer with a hole in it to help with the high temperature of the group head. My question is, can I purchase one of these to put in my machine? Thanks David
Looking up your order, I see that you purchased that machine in Feb of 2012. We had already begun modifying the machines with the new thermosiphon washer before that point. So your machine already has it!
