I ordered and quickly received this part last week. When I attached it there was a major leak from the place where if joined the output. I'm thinking there was an o ring or washer there when I dis-assembled it. Was there? If not, do you have an Idea about what's going on. By the way, I also tried putting the old part back on with the same results.
