Re: Island sink vent
Also referred to out here on the left coast as a "high loop" installation.
(Nice graphics Ron)

Re: Island sink vent

Re: Island sink vent
My 1968 code book has the same illustration in it, just hand drawn though.

Re: Island sink vent
Thanks. The basement had an odor and I am sure this didn't help

Nice image Ron. I saved that one for use with clients and for my own use.

Re: Island sink vent
Through the magic of Photo Shop, this is how I see that set up. I can't see how the sink would vent correcty.
Basically what I did was remove the looped piping and placed a cap on the top portion.

Re: Island sink vent
Guys, ... I guess I gave the wrong impression. I was NOT saying that the Photo Shop manipulation, verbage was my remedy and/or the correct way. I was saying (I meant) that it was just another way of looking at how the plumber could have messed up the job.
Being a former electrician in the Navy, I would often have to figure out electrical problems by looking at schematics, ... visually removing (or adding) wiring and saying "Yea, it will work that way as well" - (Hope that made sense). That pic just gave me an opportunity to play around with Photo Shop.
In its current state, I see no way of venting - even accidently. In my photo - I duplicated the problem, just piped differently and placed a cap on it.
I absolutely agree a AAV should be installed. Sorry for the confusion

Re: Island sink vent
The air admittance valve would be the most cost effective remedy for that setup. Pretty much like how Robert did in his picture but with the aav on top.

Re: Island sink vent
I understood that, and that was why I posted what I did. That your image of capping it off would be worse than what is there now, as compared to what you were saying was your impression of the net effect (which was my way of saying the net effect as currently done is not as bad as capping it off).
