Hi, my state is under IPC 2012.
Via google I found some threads that discussed the use of the low heel inlet bends but there seemed to be some dispute about whether or not they could be used for water closets due to some wording in the code. I think https://up.codes/s/connections-between-drainage-piping-and-fittings was one of the references.
Someone mentioned that under 2012 there was a notation on inlet bend usage
IPC Table 706.3 Notation f.:
"The heel inlet connection of a quarter bend may be used as a wet or dry vent if the heel inlet connection of the quarter bend is located in the vertical position. The heel or side inlet connection may be used as a wet vent if the quarter bend is located directly below a water closet or other fixture with one integral trap."
But there is
706.4 Heel- or side-inlet quarter bends. Heel-inlet quarter bends shall be an acceptable means of connection, except where the quarter bend serves a water closet. A low-heel inlet shall not be used as a wet-vented connection. Side-inlet quarter bends shall be an acceptable means of connection for drainage, wet venting and stack venting arrangements.
Now, is this interpreted as saying that type of fitting can not be used at all with a toilet? Or is it interpreted that the low heel inlet bend can not be used unless in a specific orientation?
Hammerpedia had this drawing saying it was to code:
I think I saw Terry saying to someone that it is OK to use the bend with the inlet vertical as a dry vent. It was a very old thread though so I want to have the most up-to-date and accurate information.
I want to install a toilet against an exterior wall so I will need a run of vertical pipe between the closet flange and the closet bend (to get the pipe to clear the wooden support beams), but it's basically the same configuration. I have to run it so it goes out from under the house and the vent pipe will route around the eaves and above the roof rather than risk putting holes in the metal roof. There is a large beam on the perimeter of the house that can't be drilled through to allow the pipe to pass up inside the wall.
But the main issue is whether or not I can use the low heel inlet quarter bend as pictured.
Yes or No?
