Query: Defective, with no warning that it's going to fail

I wanted to reduce the pressure in my water system. This was one of only a few devices I could find that was designed to do this function. Worked fine for a little over one month, then it completely stopped all water flow ... right outside the return window. So it goes into the recycle bin. Total and complete waste of time and money. I deserved this outcome, because other people have written of their similar experience and kindly provided warning which I simply ignored.
