Steve,

Thanks for the great write-up. Can you elaborate on what you mean by "evidence of maintenance". I have had annual maintenance done by Newell twice (actually two and a half times). I am pretty sure they did not do anything to these valves. What should I be doing? Should I make it a point to operate both sets of valves?

Please don't say anything like..."First take the poo valve apart...."
