What is a Barbers Loop and how is it done or laid out. I know that it's used as a drain/vent configuration for a sink that is not near a wall, i.e. an island with a sink. Could any body show me a drawing ?. There may be a different name for this type of venting, I heard it called a Barbers Loop. Thanks, Ben

this is an island vent...

NUmbers 2 & 4 would not typically be permitted.

code books refer to it as a "loop vent"

We called it a "yoke vent" because it looks like the device they use when milking cows. And "loop vent" usually has a different connotation, similar to a circuit vent.

the word yoke does not trigger anything in my mind that would have the word loop in it and is why i think they are talking about a loop vent and not a yoke vent. i could definitely be wrong though

PLUMBERS "Protecting The Health Of The Nation"

Take your "loop vent" put it in a barn. Then walk the cow up to it and stick its head through the opening between the two risers. Now the cow is safely yoked and you can milk it without getting kicked.

ok but i thought we were talking about plumbing vents not milking cows

PLUMBERS "Protecting The Health Of The Nation"

We were, and the cow analogy describes the vent the best. But since plumbing has some of the most vulgar, possibly sexist, terminology, you should have had no problem with the "mixed metaphor".

Yoke vents are commonly used in high rise buildings where the waste stack ties into the vent stack usually every 6 floors.

Thanks for your reply, I'm sure that this is what I am looking for (an island vent). Thanks again. Ben

Those are "relief vents".

Hj when the vent is at the top tie in on an inverted wye and the bottom a standing wye, it is referred to as a yoke vent here. /exception for sizing \allowing above tie in water flow to yoke.Used widely for multi story kitchen wm waste verticals.

As Abraham Lincoln once said when he asked the question, "IF you call a donkey's tail a leg, how many legs does he have? He answered his own question by stating that you can call a tail a leg or anything else but it is still a tail." You can call it a yoke vent, or anything else, but the rest of the industry, as far as I have ever heard or seen, calls it a relief vent.

It's been in the code books for many years on the East Coast. But then again, you might not know what a shoebe is either.....

Nope, but then I am not from New York or Pennsylvania, and have never been to a Jersey beach, and even if I had, I would not have brought my lunch in a ShoeB(ox).

If you did visit, you would probably be recognized quikly. Wearing shoes on the beach!

Would blue jeans also be a clue? What do you do with shoebe's? Do you tie them to a boat and use them for shark bait, but tell them you are taking them waterskiing?
