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

The place was built in 1980, was has the installation tech changed since then.

matthew,
my 1976 u.p.c. has the verbage to go along with ron's illustration!

[Ron Hasil]

My 1968 code book has the same illustration in it, just hand drawn though.

Thanks. The basement had an odor and I am sure this didn't help:)

[Jim Robinson]

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

Through the magic of Photo Shop, this is how I see that set up. I can't see how the sink would vent correcty. :rolleyes:

Basically what I did was remove the looped piping and placed a cap on the top portion.

Which is worse than what was there.

At least originally there was the possibility that some venting might accidentally take place. You have now removed all that possibility.

Best to at least put an AAV valve in place of the cap.

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 :D

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.http://www.rd.com/images/tfhimport/2003/20031001_Ask_Handyman_page002img001_size2.jpg

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).

That would be the easy solution ... unless you are in Illinois ... where AAVs are not allowed to be installed.

And at least 10 other states that do not allow AAVs.
