San-T for Vent


Is it permissible to use a San-T like I have in the picture. It is going vertically to a Vent only--not a drain.

To the left is the washer trap. The right is towards the sewer.

Thanks for any help!

You must use drainage fittings below the flood level of the fixture. A wye and eight bend should be used instead. But no one will probably notice the tee.

Not required in my area. Must be different in yours?

Agreed, as long as it's not more then 45* from the vertical

uniform plumbing code 905.2 Vents less than six inches above the flood level of the rim of the fixture SHALL be installed with approved DRAINAGE fittings, material and grade to the drain.

Thanks

That's not what my 905.2 says... "where vents connect to horizontal drainage pipe, each vent shall have it's invert taken off above the drainage centerlne of such pipe downstream of the trap being served".
But I will say that a combo is the preferred method. However. if santees are not allowed, i've got 20+ years worth of rough-ins in multiple states to change. Besides, who said he works under the UPC?
BTW, I still plumb under a revised 2003 UPC, but I understand Idaho is/has adopted it's own code. So, more battles with the AHJ

I'm in Canada. I've noticed our plumbing codes can be a little more permissive than yours. From what I can see in ours, there is no difference for vent fittings regardless of the proximity to the flood rim. That fitting would be permitted where I am, in its present location. I will admit that its easier to find code references from the U.S. and have gotten happy smiles from inspectors when I used them here.(They were pleased to see someone went above code, I guess)

Mine doesn't say that either.....

That even seems kind of vague, actually


The section i have that discusses what YOU'RE talking about is 905.3

Unless prohibited by structural conditions, each vent shall rise vertically to a point not less than 6 inches above the flood level rim of the fixture being served before offsetting horizontally, and where two or more vent pipes converge, each such vent pipe shall rise to a point at least 6 inches above the flood level rim of the plumbing fixture it serves before being connected to any other vent. Vents less than 6 inches above the flood level rim shall be installed with approved drainage fittings, material and grade to the drain.

The whole section is talking about where vents travel horizontally to connect to one another....

Anyway, code is open somewhat to interpretation.....

I have seen a plumber inspection make people tear out fittings that weren't drainage below the flood level as mentioned. Just thought I would give a heads up. Some inspectors don't know or care. But that is the code.

Thanks
