//Quick answer
- Shared drain lines mean the blockage is often not in the unit that reported it.
- Shared water heaters and recirculation loops are commercial water heater work.
- A camera locates the cause and shows which line it is in.
- Licence and insurance documentation available on request; invoicing terms not published.
01Definition
What is different about a multi-unit building?
Stacked and shared drain lines, one or more sewer laterals serving many units, and often a central water heater or a recirculation loop instead of one heater per unit. A problem in a shared line surfaces in the lowest unit first, whatever caused it. Access runs through occupied units and common areas, which changes scheduling.
What does a property manager actually need?
A single call that gets a licensed, insured crew on site, a camera that shows where the problem is and which line it is in, a plain answer on repair versus cleaning, and a water heater service that keeps the building's hot water on. Done-Rite is CSLB C-36 #998069, licensed, bonded and insured with workers compensation, and runs a 1-hour response with 24/7 emergency service.
02When it applies
When is the cause in the shared line?
When more than one unit backs up, when the lowest unit floods while upper units seem fine, or when a single unit keeps clogging on a schedule with nothing unusual going down its drain. The main line cleaning ($99 to $350) and the camera answer it; jetting at $650 to $850 cleans a building line that has coated up.
When is it the central water heater?
Complaints of no hot water across several units at once, long waits at the far end of a recirculation loop, or a tank at the end of its life serving the building. Light-commercial tanks and recirculation systems are Done-Rite's commercial water heater service.
03What goes wrong
What goes wrong when the building line is treated as a unit problem?
The same unit gets snaked every month while the real blockage in the shared line grows. The camera ends that cycle by showing where the problem is, which also settles who is responsible for it.
