Thanks for the replies, esp the link to the valve, that was my next option. All the big brand rv dealers eBay and others were out of the valve I needed. Friend I work with has a brother working for Johnny's RV in Theadore AL, they had two of them. Problem is fixed now with a spare. It is apparent that this valve has a high failure rate so the shutoff valve is a good idea. Wife is happy I'm happy.
Now if I could find a portable bandsaw mill that easy!
