In Castle Rock, the drains inside your home and the line that carries wastewater off the lot are private plumbing, and that is where nearly all clogs happen. A plumber clears them and can tell you if the problem goes past your property. Call the number on this page to be connected with a local plumber in Castle Rock.

About Castle Rock
Castle Rock is the Douglas County seat and a large, growing town on I-25. Castle Rock Water, the town-owned utility, supplies water to most homes, though some areas with Castle Rock mailing addresses, such as The Village at Castle Pines, are served by other districts. Your utility bill shows who handles water and sewer at your address. One local detail touches drains directly: Castle Rock Water does not recommend water softeners because of the salt they add to wastewater. If you are weighing a softener because of hard-water scale, that is worth knowing before a plumber installs one. In newer homes with plastic drain lines, clogs usually come from grease, wipes and food rather than failing pipe; older homes may also have roots or scale to deal with.
First steps when a drain backs up
- Figure out the scope. Run water briefly at one other fixture. If only one drain is slow, it is a local clog; if water rises elsewhere, it is the main.
- Stop water use for a main line clog. Hold off on showers, laundry and the dishwasher.
- Protect the lowest level. Move belongings away from a basement floor drain or shower.
- Leave the chemicals on the shelf. They seldom clear a main and make the plumber's work hazardous.
- Find the cleanout if you can. A capped pipe near the foundation gives the plumber easy access. Do not open it if wastewater is backed up behind it.
- Call. Describe what you saw and when it started.

What affects the cost

- A camera inspection to find out why the line keeps clogging
- Off-hours visits
