I am in the Seattle area and I have a question regarding clean outs.
I have a basement that is plumbed separately through a back water valve due to being below the upper man hole cover on the street. The toilet is the upper terminus of the basement drain line. It runs approximately 3 feet horizontal then goes through a backwater valve and connects to the horizontal main drain through a Wye. The main horizontal drain has a 3” clean out upstream.
The basement toilet does not have a clean out. I am hoping that since it’s less than a 5’ run before joining the section that has a clean out I am covered. But the code also says you need a clean out at the upper terminus. Does that trump the 5’ exemption rule? The vertical vent on the toilet is 2” so I can’t install a clean out on the vent. Am I code legal?
Any help would be highly appreciated. Thanks.
