Bullhead tees

Member Posts: 167
I see a lot of mention on here of bullhead tees but when I see them mentioned I don't always see what I know of as a bullhead tee. I was taught to measure a tee as run run branch. A bullhead tee has a larger branch than the runs. So a bullhead tee would measure 1x1x1 1/4 with 1 1 /4 on the branch. Did I get taught wrong from the beginning? Or do some people use the term bullhead differently?

An example of a bull head tee. The branch connection is larger than the run connections.
when talking about piping installations, bull heading is as Jamie mentioned Flow entering the branch connection and going two different directions,
when used in hydronic piping the flow doesn’t always divide up the way you expect
That practice used to be prohibited in codebooks, Im not sure if it is still includedBob "hot rod" Rohr

A "bullhead tee" is the name for a tee where the branch is larger than the runs. A "bullheaded tee" is any tee used in such a manner that the branch is being fed. A 1x1x1 tee where the flow enters the branch is bullheaded. Primary/secondary piping with closely spaced tees, the supply side is technically bullheaded.0

@yellowdog As mentioned above you are correct and not taught wrong.
When asking for/ordering a tee, to help prevent confusion you should describe a tee as you have said above. The word(s) bullhead helps those who are completing an order to know that the branch is larger than the run.
If they don't get it right from there, then they are a bullhead.
