A sewer backup is not a normal clog. Here is what to do
A backed-up sewer line sends waste water the wrong way, back into your tubs, toilets, and floor drains. It smells bad and it spreads fast. And it is not something to wait out until morning.
Arvada Pro Plumbing built our emergency line for exactly this. Our licensed master plumbers show up ready to clear the blockage and stop the damage before it spreads further into your home.
Older Arvada homes built before 1970 often still run on vitrified clay pipes. Tree roots find every hairline crack in that old clay and grow straight through it, which is one of the most common causes of a full backup we see on service calls.
Spring snowmelt and heavy summer storms add another layer of risk. Runoff overloads older lines fast, so a basement with a weak or failing sump pump takes on water right when the sewer line is already struggling to keep up.
Let’s cover the warning signs, what actually causes this, and what our team does to fix it for good.
When a backup needs a plumber right now
A single slow drain is usually no big deal. Multiple slow or backed-up drains at once is a different story.
Do not run water anywhere in the house once you notice sewage backing up. Every flush and every load of laundry pushes more water into a line that already cannot drain.
- Water backing up in the lowest drain first: Tubs, showers, and basement floor drains back up before anything upstairs.
- Gurgling toilets or drains: Trapped air escaping means something is blocking the main line.
- Sewage smell inside the house: A strong odor points to standing waste water somewhere in the system.
- Multiple fixtures backing up together: One clogged sink is a fixture problem. Several at once is a main line problem.
- Standing water or a soggy patch in the yard: A leaking or collapsed line under the lawn often shows up as a wet spot that will not dry out.
Do not touch the water or the area around it. Raw sewage carries bacteria and viruses that can make you sick, and the CDC recommends rubber boots, gloves, and goggles for anyone near it. Call us and we will walk you through what to avoid until we arrive.
What we use, and why
Every sewer backup has a cause, and guessing at it wastes your time and your money. We start with a camera inspection so we know exactly what we are dealing with before any equipment touches your line.
A single root intrusion or a small blockage usually clears with mechanical snaking. A line full of grease, scale, or heavy root growth needs something stronger, so we bring hydro jetting trucks that blast pressurized water through the pipe.
| Feature | Mechanical Snaking | High-Pressure Hydro Jetting |
|---|---|---|
| Best Used For | Single clogs, minor root intrusion | Grease buildup, heavy roots, scale |
| How It Works | An auger cable breaks through the blockage | Pressurized water scours the full pipe wall |
| Average Pressure | N/A (relies on torque) | 1,500 to 4,000 PSI |
| Long-Term Result | Opens the line for water to flow again | Restores the pipe close to its original width |
We will tell you honestly which one your line needs. Jetting costs more, and we are not going to sell it to you for a problem that snaking will fix just as well.
Once the line runs clear, we verify it with a second camera pass. You get to see the footage so you know the job is actually done, not just quiet for a few days.
