A Centennial plumbing inspection is a plumber's check of supply and drain piping, shutoffs, fixtures, water pressure and the water heater, plus an optional sewer camera run. Because water and sewer here come from separate districts, part of the job is knowing which rules apply to the address. Call the number on this page to be connected with a local plumber in Centennial.
Districts, not the city
Centennial doesn't run its own water or sewer. The city points residents to several special districts, and much of its water arrives through Denver Water distributors. The city's maps list water providers including Southgate, Willows, ACWWA, East Cherry Creek Valley, Inverness and others, and a separate set of sanitation districts handles sewer. The district on the water bill is the one whose rules govern the service line and any backflow device.
As an example, Southgate's rules make the owner responsible for the service line on the owner's side of the curb stop, the meter and the meter pit, and they list backflow devices among the owner's maintenance items. Other districts may divide things differently, so a plumber will want to know which one serves the address.
Comparing your options
| Visit type | Includes | When it makes sense |
|---|---|---|
| Standard inspection | Water heater, visible supply and drain lines, fixtures, pressure, shutoffs | Most purchases and annual checkups |
| Inspection with sewer camera | Standard items plus video of the sewer line | Mature trees, older streets, past backups |
| Pre-remodel check | Condition of pipe in walls you plan to open | Kitchen or bath projects |
Warning signs worth mentioning
- Water stains on a ceiling below a bathroom
- A slow main drain or a smell from a basement floor drain
- Water heater rust, a leaking valve or no expansion tank
- Low pressure at upstairs fixtures
- Sprinkler valves or a backflow assembly with no service history
- A toilet that runs on its own or rocks on the floor
Point these out when you call. A plumber can spend extra time on the area you are worried about rather than giving every room the same quick look, and can tell you which problems are cosmetic and which ones are worth negotiating over.
Seasonal timing
Spring and fall are easy times to book. In fall a plumber can confirm hose bibs are frost-proof and that the sprinkler system was drained before the first hard freeze, which matters in a climate with cold nights and big daily swings. Any plumbing or gas work that follows needs a permit from the City of Centennial Building Division.
