Hi Brain,
I found a couple of copper washers that will work for shims to get the system pressure up. I put on two, but as per your experience I will take one out before testing again. I got brave enough to take the WUR apart. It is an interesting unit and I am beginning to understand how it operates. I have some very good technical help and tools to put voltage to the unit and watch how it works. I think I am going to have to knock the valve assemble up a little more out of the WUR body to lower the warm pressure. I will know more later in the day. I blew the valve out with compressed air them shot carb cleaner through it. There does not appear to be any obstruction. I will post what I find out.
