First my two questions, hopefully simple for the experienced to answer:
1) Does code allow the top of a 3"x4" closet bend be cut shorter?
2) Does code allow the use of an additional length of PVC to be cemented inbetween the closet flange and the closet bend - a sort of extension? If so, can it be 3" PVC?
As to why I need answers to these questions, here's the situation:
I am installing a new toilet in a new bathroom located within an unfinished space on the 2nd floor of a residence. The space underneath will also be finished at some point but right now it's unfinished. The drain for the toilet will be 3" PVC, and will run horizontally down the wall behind the toilet and tie into the main stack. The joists underneath the bathroom subfloor are 2"x10"s.
I'm having some trouble planning how to connect the toilet flange to the 3" drain... everything I've read says to use a fitting called a "closet bend". So I went out and purchased a 4"x3" reducing closet bend (as seen here:
The problem is this fixture, because of it's fixed height, may not work well in joining the drain to the flange. I guess I have 2 options here: 1) I can drill a hole and run 3" PVC through one of the floor joists and into the wall, or 2) I can make a soffit in the space beneath the bathroom and drop the drain below the floor joists to avoid having to drill large holes. If I choose the first option, the hole I drill in the joist will have to be dead in the center so as not to fail the framing inspection, so the closet bend will be too tall. - It will stick out WELL above the subfloor. On the other hand if I choose the second option, the closet bend will be too short. - The top of it will be located well below the subfloor.
So I'd like to know if a closet bend can be cut or extended to fit my installation.
Thanks in advance for any insight and advice!
