Problem is I had a plumber do the inside work for me...I am not so skilled at soldering, etc.You are not reducing any of the water hammer the plastic valve is receiving. Do yourself a giant favor and install something like a Wilkins BR4 pressure regulator at the point of connection for the system. Let the hammer forces go no further than the brass PRV. You can set its outlet pressure to whatever works for you.
