Key takeaways
- A shared main serves many units
- The lowest unit backs up first
- A scheduled scope gives the board data
- Maintenance is cheaper than a flood claim
The shared line problem
Condominiums and townhomes often share a main that serves a whole building or cluster. One root mass or break affects everybody, and the lowest unit takes the water first.
Who pays and who fixes becomes a governance issue as well as a plumbing one.
Know the system
A map of the shared lines, with materials and depths, is the first step. Many associations discover that nobody has one. A locating and camera survey creates the baseline.
Include storm lines and catch basins, which are often neglected.
Schedule inspections
Annual or biennial camera inspections of the shared mains, with cleaning where needed, keep problems small. Findings go into the reserve study.
Organize records by building and line.
Communicate with owners
Give residents clear rules: no wipes, no grease, report slow drains early. A short notice before maintenance days helps access.
Footage helps the board show owners why spending is needed.
