Hydro jetting clears a Thornton home's main drain or sewer line with a pressurized water jet that removes grease, sludge, scale and roots from the pipe wall. It's the usual step when a line has been snaked and keeps clogging. Call the number on this page to be connected with a local plumber in Thornton.

What happens when you call
The number on this page connects you with an independent plumber who works in Thornton. You'll be asked which drains are slow, whether it's the lowest fixtures in the house, and roughly when the house was built. That last question matters here, because Thornton's older south side and newer north side tend to have different pipe.
On site, the plumber opens a cleanout, may run a camera, and jets toward the city main. The nozzle scrubs the full circle of the pipe and flushes debris downstream, and a follow-up camera pass confirms the line is clear.
Cost factors
- Cleanout access versus working through a toilet or vent
- Length of the line to the main
- Roots and scale in older pipe versus grease in newer pipe
- Camera inspection
- Night or weekend timing
Thornton conditions
Thornton is a large, fast-growing suburb of about 142,000 people along I-25. Census survey figures put the median home at 1997, with about 22% built before 1980. That older share is concentrated in the south, in housing from the 1950s through the 1970s, while newer subdivisions spread toward E-470 and State Highway 7.
In the older homes, drain lines may be cast iron inside and clay outside, where scale narrows the pipe and roots work into joints. Thornton's water is hard, and while hardness mainly shows up on fixtures and water heaters, older drains also collect mineral and soap deposits over time. In newer homes, plastic drains don't scale or rust, and clogs come from grease, wipes and lint. Jetting handles both; a camera look tells the plumber which case applies.
The City of Thornton maintains the wastewater lines, and wastewater is treated at Metro Water Recovery. For sewer problems in the city's system, call Utilities Operations at 720-977-6500. If the city's main is clear, the problem is in your private line. Plumbing modifications need a city permit through the Building Inspection Division (303-538-7250).
