Hi Everyone -
Please excuse this amateur hour moment... I'm a bit confused about code, vs best practices, vs bare necessities as it concerns cleanouts. I've read the UPC section and get the basic requirements. What I'm confused on is:
1. Can cleanouts be inside an interior wall - i.e. behind the drywall, and is this standard practice (w/ or w/o access panel)
2. They are supposed to be opposite the flow, or min 90* to facilitate snaking. Real world obstacles like studs, walls, finished surfaces sometimes make this impossible. What's the next best option (see photo below).
3. Beyond the 50', change in direction, main drain/stack requirements, are cleanouts frequently installed at: a) single lavs b) kitchen sinks c) washer standpipes
Related to 2. above, the arrows show the drain flow direction (forward for ~1', then right to sewer). Can I use a 90 or 45 or something to not break the cleanout orientation rule? Kind of seems self defeating. The other three directions are blocked by 3" pipe, shower tile, and the stud. What about a wye? Seems if the snake was pointing down already, it would have less trouble making the bends. The access is the mech room, so aesthetics aren't much issue.
