Context: Connecting a 1.5 in diameter 42in long sink + dishwasher trap arm into a 2in diameter drain.
- How far, from the trap to drain connection, does the vent on the 2in diameter draine line have to be located? from my research I am getting 5ft but also 8ft from the connection.
- Can the re-vent of the laundry sink be removed, if the drain is a 2" pipe rather than a 1.5in pipe?
- How long can the trap arm be if the 2" drain to the vent is 8ft?
