Number Of Bends In Sanitary Drain Pipe


Hi guys,

A HO wants me to open up an existing L.B. wall and make it a knee wall with posts. Basically a "window" look.

I have a 3" or 4" drain pipe running in the middle of the wall (where I want to open up). Which means re-directing the pipe into a BULK HEAD, then back into the wall, at a different point beside the posts (on either side).

This means 7 90 degree bends between the ceiling of the first floor and the cleanout above the basement slab. I don't know how many times it has bent in the ceiling of the first floor.

45's are possible, it will just increase the size of the bulk-head. I'm at the feasibility stage and promised the HO I would find out if there any issues with this before I start designing this knee wall. At some point my plumber will deal with it but I need to know whether it is even possible.

Any ideas?
Thanks in advance.

What you plan to do on the top, after you cut the studs, you will need a header to carry the above load... I think the pipe bends are the least of your problem.

Re: Number Of Bends In Sanitary Drain Pipe


Whats below the floor. To redirect the flow in walls below?

When we run into plumbing like that we try to go with other options/designs.

Good luck.

That's why you insulate the wall.

Just hang a mirror and both sides of the wall the same size as the proposed opening, MUCH EASIER!

Btw what is that at the bottom of the wall next to the wall receptacle, a register or is it for return air?

I want to see the progress pic of this project.

I looked it up myself which is why I couldn't find anything.

It's a good thing I don't live in California.

The NYC code which is based on the ICC states that one cleanout is required every 40 feet of developed length when there are multiple changes of direction. 708.3.3.

Nothing about total degrees of fittings.

Tough guy.

Re: Number Of Bends In Sanitary Drain Pipe


Do u mean IRC ? the ICC is the international code council the governing agency for jurisdictions and inspectors. They dont write the codes. The IRC international residental code states each fitting with a change of direction graeter than 45 degrees in a building sewer, building drain or horizontal waste -where more than one chage of direction occurs in a run only one per 40 feet of developed length.

The uniform plumbing code UPC is what we here in Ca. base the code on and the UPC states every 135 degrees and 100 feet


I looked it up myself which is why I couldn't find anything. REALLY?
just kidding about the tough guy stuff im sure u can plumb circles around me
