A clogged sewer line usually shows up in more than one place. Several fixtures drain slowly, a toilet gurgles when the washer runs, or water backs up in a basement floor drain. Stop using water and find your cleanout.
A plumber can clear the line, and a camera shows why it clogged. If the cause is a break, roots, or a sag, the fix may be sewer line repair instead of cleaning alone.
Signs the problem is the main line, not one drain
One slow sink is a branch problem. These point further down.
Several fixtures slow at once.
A tub, a sink, and a toilet all draining badly share one line.
Gurgling in unrelated fixtures.
Air is pushed through traps when water cannot move past a restriction.
Basement floor drain backing up.
The lowest drain in the house is usually the first to show a blocked main.
Toilet water rises when you run the washer.
Washer water reaches the blockage and has nowhere to go.
Sewer smell indoors or in the yard.
A broken line or a persistent backup can release gas and moisture.
Lush wet patch in the yard.
A section of lawn that stays soggy can point to a cracked line underground.
Locating the cleanout before you need it
A cleanout is a capped pipe that gives direct access to the sewer line. It is often outside near the foundation, in a basement, or in a crawlspace, and it is usually a few inches wide with a screw cap. Licensed plumbers work to the 2021 International Plumbing Code (IPC) as adopted in Colorado for cleanouts, so ask the Firestone building division whether adding or moving one needs a permit.
Find yours on a dry day. Knowing where it is helps a plumber start sooner.
Do not open the cap if the line is full and backing up. Pressure and sewage can come out fast. Leave it closed and call.
What to do right now if sewage is backing up
Act fast but stay safe.
Stop all water use.
No flushing, no laundry, no showers, no dishwasher. Every drop makes it worse.
Keep people and pets away.
Sewage carries bacteria. Keep children out of the area and avoid contact.
Keep electricity away from wet areas.
Do not touch outlets, cords, or appliances standing in water.
Do not use chemical cleaners.
They rarely reach a main line clog and they are hazardous for the person who clears it later.
Call a plumber.
Dial (303) 552-3896 and say how many fixtures are affected.
What you can safely try yourself
Limit it to these steps, and stop if the water level rises.
- Confirm the scope.Run water in one fixture at a time and see which others react.
- Try a plunger on one fixture.If a toilet or tub plunges clear and the others do too, the clog was local.
- Check the cleanout from outside.Look at it, but do not open it if water is visible or the line is full.
- Stop and call.A drain machine or a camera needs a plumber.
How a camera shows the cause
A small camera on a flexible cable goes in through the cleanout. It shows the pipe wall, the material, joints, roots, sags, and breaks. The picture tells the plumber whether the clog is a one-time event or a symptom.
That is why a sewer camera inspection often follows cleaning. If the line is clean and the video shows a good pipe, you have a maintenance problem. If it shows a crack or a belly, you have a repair decision.
Ask to see the video and ask where the problem sits on the line.
Repair choices from cleaning to replacement
The right option depends on what the camera shows.
| Option | What it fixes | Trade-off |
|---|---|---|
| Cable or machine cleaning | A soft blockage or light roots. | Does not fix a cracked or sagging pipe. |
| High-pressure water jetting | Grease, heavy roots, and film on the pipe wall. | Needs a sound pipe to start with. |
| Spot repair | A single crack or a joint that has separated. | Requires digging at the point of damage. |
| Pipe lining | A cracked or root-prone run | Needs a clear line and a pipe that can take a liner. |
| Full replacement | A collapsed or badly sagging line. | Largest job and most disruption. |
Do not accept a replacement without seeing the video. Ask what the camera showed and why the chosen option fits it.
Why the same clog keeps coming back
A clog that returns often has a cause that the first cleaning did not remove. Common ones are roots entering at a joint, a sag that holds water and solids, or a section that has shifted.
Cleaning clears the symptom. Only a camera shows the cause. If the line has needed clearing more than once, stop paying for repeat cleanings and get the video.
What you can do to keep the line clear
Flush only toilet paper and human waste. Wipes sold as flushable do not break down the way paper does, and they catch on roots and rough spots.
Keep cooking grease out of drains. Let it cool, scrape it into the trash, and wipe the pan before washing.
Watch where you plant. Tree roots follow moisture to a joint, and a cracked line is a free water source.
What this means in Firestone, CO
Since the bulk of town was built after 2000, many homes have plastic sewer lines, which resist rust but can still sag or separate. Original townsite homes are much older, and older pipe materials are possible, so the camera matters before anyone assumes what is underground.
The Colorado Geological Survey says expansive clay is the state's most significant geologic hazard, and poor drainage next to foundations can move soil. A soil engineer decides whether that applies to your lot, and we only deal with the pipe side.
If your property near Frederick or rural Weld County is on septic instead of a municipal sewer, the repair path is different, so say so when you call. The same advice covers sewer lines in Dacono, where we also take backup calls.
Questions homeowners ask
A small hand tool can clear a local clog. A main line is long, and a rented machine can damage a pipe or leave the cause in place. Call for anything past the first few feet.
Sewage backing into the house is. Stop water use, keep people away, and call. A slow drain that is not backing up can wait for a normal appointment.
Your plumber can find out with a camera at the cleanout. The utility handles its own main, and the homeowner usually handles the pipe on their property. Ask your utility where that boundary is.
Not always. Roots can enter at one joint, and a spot repair or lining may solve it. A camera shows how far it goes.
It can be. The original townsite holds the oldest homes in town, so older pipe materials are possible. A camera inspection shows what is there before you pick a repair.
