At present, I have 2 WCs, 1 shower, and 1 sink that all utilize a 3" copper waste.
The copper waste drops from the 2nd floor to the basement, where it has a 10 to 15 foot horizontal run. From there, it 90s down and ties into the main cast iron stack via a wye with a cleanout shortly upstream of the wye.
I've had the house for about a year, and we've had 3 backups from this line.
On the most recent go round, the last sewer cleaner did not tighten the cleanout cap tight enough (fortunately) so I noticed it dripping before the backup went all the way to the 2nd floor. There are obviously no branches in the basement or 1st floor.
The clog is always in the wye, and never has any foreign material. My guess is that solids and liquids are separating in the horizontal run, building up, and then finally heading down into the wye as one big slug of deliciousness.
By leaving the cleanout open and having my wife flush both toilets, it was noted that our most often used toilet has a much weaker flow than the other.
I'm going to confirm that the horizontal run is at 2%, but by eye it looks close. Assuming that this is not an issue, I think my next course of action is to replace the toilet.
1) Does this sound like a reasonable plan?
2) What's the best toilet for this situation. Tall and elongated are preferred.
