Sewer Line Repair

[Account Closed]

What have your experiences been with old sewer lines?  When have you decided it is definitely necessary to replace them?  I have a unit that was really backed up and likely hadn't been serviced for years and years.  A camera ran through showed that there is also damage in two spots.  Plumbing company spent 8 hours out there this month completely clearing the line (it was reallyyyyy backed up), so it should perform fine for at least a couple of years.  It cost me $800 to do this.  I'm expecting that complete replacement will cost 7.5 to 15k, so I'd rather shell out a grand every couple of years in the near term.  But long term it will probably need to be fixed.  Just not sure how long I should wait to pull the trigger - want to defer large expenses but also don't want a really pissed off tenant!
