In a different post I asked about whether it was to-code to have a 2" kitchen drain connect directly to the building sewer outside. Your answer: yes!
Now, I have to decide if I should reuse that drain or not. I'd like to know what would you do?
Unfortunately forum readers, it'll take a bit of explaining... Here is the situation: the 2" drain mentioned is an old 2" cast iron hub & spigot (possibly as old as the house--1907) that slopes perhaps a little steeper than 1/4" per ft into the unfinished (dirt) floor of a storage room. (We will be finishing the storage room w/ drywall and insulation, but not heating it--and we will pour a slab as well.) The drain leads outside and connects to the building sewer as mentioned above. Downstream from this connection is the main stack connection to the sewer. We had the sewer scoped from the main stack onward, but the camera did not fit in the 2" drain so we have no way to know the condition of that drain/sewer, which sit upstream of the stack. The sewer scope guy said the 2" drain was likely connecting to a 3" sewer and that may be hard to clean out should the need arise (both because of size and that it would have to be dug up).
Were we not to route the kitchen drain through this 2" drain, we would have to run an additional 27 ft horizontal to reach the main stack / sewer connection. (This can be done w/ correct slope, for a total horizontal run of 36'--we'd be taking a higher route of course than the existing drain).
Keep in mind, this is a full-remodel and all new plumbing is installed elsewhere above the basement level. Also we have not lived in the house so have no history/knowledge of that drain's performance.
So without knowing the condition or performance of the drain and given the sewer scope guys comments, would you tap into that old spigot and hub 2" line or run all-new to the main stack?
Should we choose to reuse the existing 2" drain and to pour a new slab, does whatever connection is made to the CI spigot & hub drain have to remain exposed above it or can it be embedded in the slab?
