Are bath waste traps all the same fitting? I need something smaller
than what i've got which is about 5 n a half inches and leaks.

TIA

We were somewhere around Barstow, on the edge of the desert, when the
drugs began to take hold. I remember jaz saying
something like:

Are bath waste traps all the same fitting?

Generally, yes.
