Commercial Water Line Service for Denver Properties

A commercial property runs a larger service, sometimes with a backflow preventer and a dedicated fire line, and a failure on it affects tenants or an entire operation rather than one household. Afford-A-Rooter locates, repairs, and replaces commercial water service lines, and works with property managers on scheduling that does not shut down a building unnecessarily.

How is a commercial water line different from a residential one?

Commercial services are typically larger in diameter to support multiple units or higher fixture counts, and many properties have a backflow preventer required at the point of service along with a separate fire suppression line. A failure on the domestic side has to be diagnosed separately from the fire line, since the two run on different schedules and different code requirements even when they enter the property close together.

  • Larger diameter mains serve multiple tenants or a higher fixture count
  • Backflow preventers are commonly required on commercial services
  • Domestic and fire lines are separate systems even when routed near each other
  • A failure can affect every tenant in a building, not just one unit

Call for commercial water line service when

  • Pressure has dropped across multiple units or the whole building
  • A wet area has appeared on the property between the meter and the building
  • A backflow preventer is failing inspection or testing
  • The water bill for the property has jumped without an operational change
