OK. My turn with a cast iron and ABS problem. Its pretty simple, really. I've got this cast iron Y piece into which a kitchen drain is connected. The problem is that the 2" ABS that feeds into it (on the attached picture, that's the connection at the top, just after the 45 degree elbow) is pretty much horizontal over a distance of about 20 feet, so needless to say it needs to be unclogged maybe once every 6 months. To fix this problem, I reckon that I should lower the kitchen drain connection by 5 or 6 inches which should give me enough slope. I've never played with cast before, but the job seems to be pretty straightforward to me:
1) With an angle grinder, I'll cut the straight piece that sits between the cast 4x4x2 and the 4x4x3 Ys, maybe a couple of inches below the hub. I think I've got enough room for this all around.
2) I'll get rid of the remaining piece of straight pipe, and of the 4x4x3 below it.
3) I'll permanently cap the 2" connection on the 4x4x2
4) With a hubless coupling, I'll join the shortened cast iron piece to a small section of 4" ABS below it, which will then be joined to a new ABS 4x4x2 (which will now be at the correct height), followed by another piece of 4", followed by a new ABS 4x4x3 for the lower connection...
Am I missing anything, here, or is this the extent of it? Any trap, pitfall, etc. I have to be aware of? Thanks for any suggestion or comment.
