A bit confused over terminology on this, was wondering if anyone can clarify
it for me.
Regarding the typical under sink bathroom drain traps:
I always thought these U-bend assemblies were called "J" Traps.
But I see that in some text they term them "P" Traps.
What are the differences between a J and a P Trap, then ?
Couldn't find any good pix of these two types; anyone know of any links
showing differences, etc. ?
