When a drain backs up, one of the first things a plumber will ask is, “Where is your cleanout?” If you do not know, you are not alone. Plenty of Colorado Springs homeowners have never needed to find it. But knowing where your sewer cleanout is can save time when trouble hits, because it gives direct access to the main line for clearing clogs and running a camera inspection.
This guide walks you through what a cleanout looks like, where to check, and how to find yours. It is part of our full guide, sewer line trouble in your yard.
What a sewer cleanout is and why it matters
A sewer cleanout is a capped pipe that connects directly to your main sewer line. Removing the cap gives a plumber a straight access point to clear a blockage, run a drain snake, or send a camera down the line without going through an indoor fixture. In Colorado Springs, the sewer service line from your home to the city main is the homeowner’s responsibility, so easy access to it is worth having.
Locating it ahead of time matters because:
- It lets a plumber clear a clog faster and with less mess.
- It gives clean access for a camera inspection to diagnose deeper problems.
- In a backup emergency, a plumber may be able to open the cleanout to relieve pressure and stop sewage from rising inside the house.
What a sewer cleanout looks like
You are looking for a short, round pipe sticking up a few inches from the ground, or a capped access point set flush in the ground or a wall. Common signs:
- A white or black PVC pipe, roughly 3 to 4 inches across, with a screw-on or push-on cap
- A cap that may be labeled “cleanout,” “sewer,” or “C.O.”
- Older homes may have a cast iron fitting with a square nut on top instead of a plastic cap
How to find your sewer cleanout, step by step
- Check outside along the foundation. Walk the perimeter of the house, especially the side facing the street. The cleanout is usually within a few feet of the foundation, on the path between the house and the city main.
- Follow the line toward the street. Your main line runs from the house out to the city connection. The cleanout typically sits somewhere along that route, so scan the ground in that direction.
- Look in the landscaping and grass. Cleanouts often hide under shrubs, mulch, tall grass, or a light covering of soil. Check flower beds and along fence lines. Part the grass where you expect the line to run.
- Check inside if you have a basement, garage, or crawl space. Some homes have the cleanout indoors, on a lower-level wall, in the garage, near the water heater, or in a utility area. Look for that same capped fitting.
- Note the location for next time. Once you find it, mark it or write down where it is. When a backup happens, you will not want to be searching in the dark.
If you walk the yard and still cannot find it, that is fine. Some cleanouts are buried or were never installed in an easy spot. A plumber can locate it, and if your home lacks an accessible cleanout, one can be added. In fact, Colorado Springs Utilities suggests a contractor-installed outside cleanout so the line can be cleared without the mess of working from inside your home.
Found the cleanout but still have a clog?
Locating the cleanout is step one. If your drains are slow or backing up, the next step is clearing and diagnosing the line:
- Drain cleaning clears the blockage and gets flow moving again.
- Hydro jetting uses high-pressure water through the cleanout to scour out grease, scale, and root debris that ordinary snaking leaves behind.
Colorado Springs Utilities recommends having your service line professionally cleaned about every two years, and more often in older neighborhoods with large trees, since thirsty roots work their way into pipes. If clogs keep returning, that is a sign of a deeper issue like roots or a bellied line. A sewer camera inspection through the cleanout shows exactly what is going on. Call Alphalete at (720) 807-3224 to schedule.
When the real problem is the pipe itself
Sometimes a cleanout and a cleaning are all you need. Other times the camera reveals cracks, root intrusion, or a collapsed section. When that happens, Alphalete can repair the line with trenchless methods that work through small access points and protect your yard and landscaping. See our trenchless sewer repair in Colorado Springs, backed by a 20-year warranty with a properly installed liner expected to last 50 years or more.

Frequently Asked Questions
Where is my sewer cleanout usually located?
Most often outside, within a few feet of the foundation on the path between your house and the street, hidden in grass or landscaping. In some Colorado Springs homes it is indoors, in the basement, garage, or near the water heater.
What does a sewer cleanout look like?
A short, round, capped pipe, usually white or black PVC about 3 to 4 inches across, sometimes labeled “cleanout” or “C.O.” Older homes may have a cast iron fitting with a square nut on top.
What do I do if I cannot find my cleanout?
A plumber can locate it, and if your home does not have an accessible cleanout, one can be installed to make future clearing and inspections easier.
Can I use the cleanout to fix a clog myself?
You can open it to check, but opening a cleanout during a backup can release sewage under pressure. For a clog that keeps returning, it is safer and more effective to have the line cleared and camera-inspected professionally.
