Hi ,

I am planning to put a wetbar sink in my basement , but total length of the pipe (from the sink to the drain) is around 9 ft.
Canadian plumbing code mentions the maximum trap arm length of 6ft (2.5.6.3) , so If I add a vent pipe in between , would it be acceptable ?

What I am confused about is the 6ft rule for 1.5 inch ABS , is it the maximum length a pipe can have or maximum length without vent pipe.

Normally a vent should be located with in 2 feet of the trap and the fixture with in 2 feet of the trap that gives you 4 feet of play

The max length rules are going to be for the trap arm, and the trap arm ends at the vent.

There is also a minimum length for a trap arm -- probably 2 x the nominal pipe size. So with 1-1/2, trap arm needs to be at least 3 inches. This was probably not going to come up, but there it is.

This is awkward, but...
