Hi all
I am venting a kitchen island sink. Is there a limit to how far you can run horizontal to connect to the main vent stack after you have run your loop vent under the island? Thanks !! |

| I may have answered my own question. It seems the max. horizontal run after the loop vent is 6 ft for a 2 in pipe. Does this sound about right? |

"I may have answered my own question. No. It doesn't sound right. There should be no limit at all for the length of a horizontal run or 'foot vent' that gets connected to a main stack. The only limit in most cases would be on the horizontal length of the trap arm between the sink trap and the island vent itself...which is limited to 8 feet for 2" pipe. See the links below for how Code compliant Island vents should be installed under most codes: http://www.terrylove.com/images/island_vent.gif If your kitchen island vent doesn't look like the above diagrams, you're not installing the island vent properly. |
