Our washing machine used to dump into a utility sink, and the utility sink drained with a 1 1/2" wet vent 9' over to the 1 1/2" kitchen sink vent stack. Took too long to drain, made awful noises, ugly, and probably not very well designed.
So I'm fixing it.
Anyway, I have a 1 1/2 line horizontal line from the utility sink trap and a 2" horizontal line from the standpipe trap coming together at about the midpoint between them, so there's about 30" of horizontal run for each. From there, they meet in a double combination wye with the vent coming up and out to the roof (single story).
So here's my question (provided nothing said sofar raises red flags with anyone)... Those horizontal runs, do they need cleanouts? Looking at Terry's rough-in example (the one with the insulated pex (http://terrylove.com/images/washer_rough_b.jpg)), I don't see any cleanout at the standpipe trap. I'm intending to put a cleanout trap under the utility sink, but will I need some sort of cleanout between the double combination wye and the standpipe?
The cleanout is in the five foot high "crawl space"
I'm putting a cleanout below the combination wye (in the basement, as it turns to make a horizontal run to the 4" main line), but that's not going to be useful for cleaning out above the double combination wye. Is the cleanout at the sink, the standpipe itself, and the roof vent enough to satisfy my cleanout needs?
