Thanks, this was very helpful! I know exactly where the clean out is, don’t have any backups, and I do have a snake of modest length. But it’s that time of year again — the time I worry about whether I should’ve gotten X insurance coverage 😂

The real question I guess is, since there’s nothing alive anywhere near the drain lines, I guess there’s no risk of roots (we have a handful of city planted trees on the sidewalk but nothing in the alley in back). Is there anything else that I should be reasonably concerned that drano or a snake can’t fix between my house and where the city takes over?
