Hello,

Am I allowed to use the side inlet of a quarter bend as a vent when the bend is used for a toilet?

Thank you

The side inlet of that 90 isn't high enough for it to work as a vent in that configuration. The vent needs to come off the invert/ upper 1/3 of the pipe/fitting. In a horizontal to vertical configuration, the side inlet is entering in the flooded portion of the fitting.

That's a nice diagram, but I'm not sure I believe it. Too bad it doesn't indicate which plumbing code it is about, with references to the appropriate sections.

Cheers, Wayne

I had found a near identical diagram from IAPMO but it didn't have that particular fitting in that particular configuration, but did have a san tee version and indicated it was not to be used for a vent.

Actually.. maybe I was misinterpreting that.. Is this diagram indicating that the side "Pattern" ie the side inlet could be used as a vent in that configuration? I was thinking that it meant the fitting could be used in a vent system.. But maybe i was wrong.. and perhaps that would included the side inlet 90?

No, I think my original take is still correct. That the tee fitting whether its a left or right inlet tee can be used in a vent system and ONLY in a drain system if used in the indicated position.

Thank you for the information and your time replying. I've been searching for another way to put a vent in with the structure I have since I posted my question. Spent most of the weekend looking for alternate ways to get a vent in. Think I've finally got it figured out. I'm going to use a wye in the horizontal waste line and come off the wye with a 45 and use it for the vent.

My thanks to everyone who replied.

Regards
Mike

is there room to install a wye and come up in the wall next to the toilet or behind the toilet to pull a vent. Only has to be 1-1/2" pipe to vent your toilet

The wall behind the toilet sits on a wooden beam I don't want to drill through vertically. If I drill horizontally through it I can come up through the adjacent wall with the 1-1/2.

Thank you

Nice website. I looked at the picture in the residential section, just me, but I remember getting slapped more than once for putting tools on a home owners nice counter top.

I know this thread is older but im in a similar position and found this.. Are we sure i cannot use the side inlet if I'm directly under the toilet. .Like 3 inches below . Its being used as the closet flange.
