I have a counter warranty so I can use that first. Wasn't there a recall on the high side valve? If yea how can I be sure that the new one I get is gonna be ok.
We made new valves and offered to them to anyone who had old valves. It actually takes a lot of force to damage the old valves but some guys will. Most guys won't ever see a problem with the old valves. Serial numbers above 12000000 have the new valves.
