Run from converted garage to house is approximately 34' long with around 90 degrees of bends (2-45's minus a slight angle coming out of the garage). I'm assuming it is best to add a vertical cleanout at the garage and at the house. Is this required? As for the 18" of clearance...is this regarding access to the cleanout(s)? In other words should there be a 'clear' radius of 18" surrounding the cleanouts or am I interpreting the code incorrectly? Does a Tee do the job?

hi Flick,

Your first cleanout should be 18" from the foundation. then Section 704.2/ chapter 7 of the Standard Plumbing Code dictates 50' apart in horizontal drainage lines and section 704.4 says a cleanout shall be installed at each change of direction of the building drain greater then 45 degrees.
good luck, Tom

Tom,
Does this mean I only need one at the exit and not anywhere else or is this the accumulated bend the code is referring to?

"Run from converted garage to house is approximately 34' long with around 90 degrees of bends (2-45's minus a slight angle coming out of the garage)."

Looks like a 90 degree bend to me. Regards, Tom

So this means another cleanout near the house? Might be obvious to you but I can lost between right after the second 45 or right before (18") the house.

Hey Flick,

Two 45's make a 90 degree bend and code calls for a cleanout at every bend greater then 45 degrees. How ever I consider that overkill, ( as I do a lot of code restrictions) so if you're not permitted and there won't be a inspection Just skip it. If you did pull a permit check local codes for a exemption. cheers, Tom

Can always count on you. Bought the Tee's and other paraphernalia this morning so I think I’ll do it right. Thanks, again!

just to add id say that it would be wise (if someone hasnt said it yet) to keep the cleanout the same size as the pipe it serves, and technically a cleanout is supposed to be designed to rod in the direction of flow but i dont think the tee is a deal killer anyways.
- good luck man

Thank you. This one looks like it's made for cleanouts...don't remember the name, though.

Flick,
" This one looks like it's made for cleanouts...don't remember the name, though."
If it's a tee with a cleanout cover already installed then you have a "clean out tee" that we use mainly on vertical stacks for a first floor or basement inside cleanout. We don't use them much outside in a trench because covering the trench tends to hide them. We use a combination wye and eighth bend, (or in the case of a shallow trench a sanitary tee) on the sewer line and raise to a cleanout set at ground level.
Cheers, Tom
