Regarding the Grundfos Video....that was good information but I had a hard time dealing with the bad acting and boring narration. I felt as if I was in my eighth grade cafeteria watching a sexual education film clip!
Your sex ed taught you about wells too? I thought it was an analogy but clearly I was wrong. Growing up in a small town in Texas all we had was well. I'm going with well. I have no dental issues and it always tasted better to me.
