Spot the Plumbing Violation

Bringing back a previously used photo I took to see if the conversation will be the same as before:

Vent below trap, see this way to often from out of the area plumbers on Residential & Commercial sites. Drives me nuts.

They could put an AAV on the fixture drain (connected to the vertical through a wye) and it would comply with the IPC.

And PEX support on those washer lines in back....The AAV fix is a good suggestion...

One wonders way they just didn't use a double san tee....A lot of extra work. (but maybe that's what was left on the truck?)

Maybe the local inspector does not allow them?...I have seen that on more than one occasion....

Yes they can cure the violation with an AAV but I'm not offering it as a solution.

Is there a state or municipality that does not allow double sanitary tees or is it an inspectors lack of understanding?

The lavatory drain on the left appears to have
very minimal slope, or even negative slope.
Maybe it is just the angle of the picture though !

It may have been a rule of thumb at some point, but mainly uninformed or over-employed inspectors.

Some people read the footnote and run with it.....


. For a limitation on double sanitary tees, see Section 706.3.
