WE are installing a toilet and have very little height to work with.. Is it against code to use a regular 90 under the toilet, or is a long sweep required.

Hi PazMN

You can definitely use a regular 90 for a toilet bend... no problem. The bigger question from my perspective is if height is restricted, how are you VENTING this toilet? Let me know, OK?

Mark raised a good question... Also, is this installation on concrete slab or are you trying to fit it between floor joists ? What makes you think you "don't have enough space to install large sweep" ?

Back to you
