Bullhead Tee's: Acceptable or not?
Bullhead Tee's: Acceptable or not?
(OP)
I'm looking for some design guidance on when bullhead tee configurations are acceptable. I know they typically are to be avoided in hydronic systems, but don't see as much emphasis against them in domestic water & domestic water heating applications. My definition of a bullhead tee configuration is one that has flow into a branch tee from the branch connection. I don't know if it matters whether flow is incoming on one of the other connections, but it's definitely a bullhead when flow is both directions out of the non-branch connection.

Bull head Tee's are appropriate for fire protection systems and for irrigation systems. They are not ideal for process piping for many reasons.

I'm not exactly sure what would disqualify any such fittings from normal fluid flow applications; however, I suspect in most cases the reductions (on the run) are "concentric" and thus such would not be good for any connection/application requiring that the continuing piping etc. be "eccentric" with the top or invert of the run. Alternatives perhaps applicable in some cases are also full-opening tees, with concentric or eccentric reducers (when available) off the run ends.
