I've drawn up my horizontal drain lines and want to get some input as to where I'll need to place the cleanouts. The house was built in 1920 and is on piers with a crawlspace.
I'm thinking about using a 3" combo wye on it's side with cleanout fitting at A in the drawing due to the fact that I'll have to have a quarter turn at that point to connect into the main branch drain. The cleanout will have to be in the crawlspace, which I understand isn't the ideal location, but I don't see that I have much choice.
Due to the layout of the crawlspace and the lack of headroom, it's going to be very difficult to have a cleanout at the full bath WC (left hand side of drawing) and I think the inspector will let me get away without one. My plumbing buddy says that one can always pull the toilet if that line has to be snaked. I don't think that is necessarily exactly to code, but it gets done of course.
At E in the drawing, I had considered using a long sweep quarter turn and then having a wye with a cleanout just upstream of it instead of the two 1/8-turn elbows separated by a length of pipe. Which would be better?
Where else should I put one if it's needed? Basically, the inspector told me that there needs to be a cleanout every time a horizontal line has a quarter turn fitting, although two 1/8-turn fittings separated with some distance of pipe appears to be acceptable.
At D where the 4' vertical drop where the drain goes underground then turns horizontal, do I need a cleanout at the base of the stack where it goes back to horizontal before exiting and connecting to the sewer stub? It's only about 12' between the vertical/horizontal junction and the city's cleanout at the stub. If I do, how should that be configured? A combo fitting with cleanout?
I know there are a lot of considerations here and I'm grateful for any insights.
Thanks!
