Reply To: DWV for a sink in an Island

[Don HenriksonParticipant]

: I am planning to install a kitchen sink in an island. The dirty arm length is approx. 8( distance fron san-tee to island), : I believe the code says a dirty arm cannot exceed 5.. Is this possible?Don, The UPC Plumbing code reads: 60 inches for 2 pipe 42 inches for 1-1/2 pipeMost island sinks are run with a loop vent that has a foot vent added.Regards, Terry Love
