I spoke with two separate county inspectors and neither could say one way or another for sure.

It all looks good to me . Except the first pic. It seems to be installed upside down, and for that matter uphill. The pics are kind of confusing icon_confused.gif


I think the S Tee is wrong.

I aint' no plumber



It seems like a "wet" vent thing. I say call a plumber.

That was the debate in the other thread.

These are all vents above the highest fixture or flood line. So, theoretically, there will be nothing but air flowing in these pipes in both directions.

I don't think it's a real big issue, but it just made sense to me that the tee be oriented in this way for a vent system. Some inspectors did not agree.

I went searching and came up with a conclusive "I'm not sure."

To be honest. I think that if it is a vent above all others, with no possibility of it being a wet vent. I really do not care which way the S-tee is situated…


The plumber used what he had. It works for him , and in this situation it works for me.


I would not put it on my report.

They are still using cast iron? Why? Must be a special reason for spending all that money and time on cast iron when PVC works better, lasts longer, and is easier to install (fewer joints to loosen and leak).

I asked that question too. I'm not sure you want to hear the answer I got. . .

They use cast iron in custom builds to reduce noise ![icon_biggrin.gif](upload://iKNGSw3qcRIEmXySa8gItY6Gczg.gif)

Or they could just insulate around the stack in sound insulation, but that would be too easy to think of?


I'd rather have that "noise" than the potential for leaks at those joints ... I can sound dampen most of that noise out.

Looks like the right hand section should have been ran with 2" pipe with a vent t instead of a y… but I would need to see the builders plans to confirm why it is not.
