MBC question
Been wondering about this....
My mbc is one of the ball and spring types. The ones you can make from common brass plumbing parts. At the back of the tee there is a small hole drilled in it. I've noticed that not all have this hole drilled in them. Is this necessary? Seems like it would work better without it.
