Can we agree on one thing? When considering the tasks that we perform on a daily basis as a maintenance organization, there is a one-right way to do them? I am not saying that I know the answer, but I believe that there is one-right way to rebuild a Goulds HT3196 LTX pump. I believe that there is one-right way to calibrate a Campbell Scientific pH probe. I would propose that the correct method to perform these tasks is a scientific fact. Now if you were to ask me who makes better music The Beatles or the Rolling Stones, well then I would of course say The Beatles, but that would be an opinion; open to debate and discussion with no clear answer.
