|Not sure what the reason for it is. I don't remember anything coming with the tank to tell you that is even there.
I looked in the tube and fitting last time and they both look clean. The marble is stainless so it blends in with the fitting. You have to actually try and blow in to the tubes or take it apart to notice there is a problem. I did not do that the first time.
You never have time to do it right the first time but you always have time to do it again.
