Why Longmont Trusts Mountain Valley Plumbing
Is Your Clog in One Drain or the Main Sewer Line?
The first step in clearing a drain is identifying where the blockage is located. In Longmont, older homes, especially in areas like Old Town, may have clay or cast iron sewer lines that are more susceptible to root intrusion, while newer neighborhoods often have PVC piping. Knowing the pipe material and the location of the clog helps our technicians choose the safest and most effective clearing method.
Signs of a Branch Line (Single Fixture) Clog:
- Only one sink, shower, or tub drains slowly.
- A nearby toilet gurgles when you use that fixture.
Signs of a Main Sewer Line Blockage:
- Multiple drains back up at the same time.
- Toilets gurgle when the washing machine or dishwasher is running.
- Sewage odors come from floor drains.
- Wastewater backs up through drains on the lowest level of your home.
Avoid chemical drain cleaners whenever possible. They can damage older pipes and make professional drain cleaning more difficult and hazardous. If wastewater is backing up into your home, avoid DIY solutions and contact a professional as soon as possible.
Rooter Service vs. Hydro Jetting: Which One Do You Need?
Most residential drain clogs can be cleared using one of two methods: rooter snaking or hydro-jetting. After inspecting your plumbing system, our technicians recommend the safest and most effective option based on the type of blockage, the condition of your pipes, and the severity of the buildup.
When Rooter Snaking Is the Right Call
Rooter service uses a rotating cable to break apart and remove common drain blockages. It’s often the best solution for hair buildup, soap scum, minor root intrusion, and other localized clogs. Because it uses mechanical cleaning instead of high-pressure water, it’s a safe option for many residential plumbing systems.
When Hydro-Jetting Is the Better Option
Hydro-jetting uses high-pressure water to remove grease, sludge, scale, and other stubborn buildup from inside your pipes. While it’s more thorough than snaking for certain blockages, older clay or cast iron pipes may require extra care. That’s why we perform a camera inspection first to confirm your plumbing system can safely handle hydro-jetting.

Longmont Drain Clearing FAQs
How much does drain clearing cost in Longmont?
The cost depends on where the blockage is located and how severe it is. Factors such as pipe condition, cleanout accessibility, root intrusion, and the need for a camera inspection or hydro-jetting can all affect pricing. Before any work begins, we’ll provide a clear, upfront flat-rate quote.
What does the $79 drain-clearing offer include?
The $79 promotional rate applies to qualifying single-fixture drain clogs with easy cleanout access. Main sewer line blockages, structural pipe damage, heavy root intrusion, or more complex repairs require different equipment and pricing. Contact us to confirm whether your situation qualifies.
Do I need rooter service or hydro-jetting?
Rooter service uses a rotating cable to clear localized clogs such as hair, soap buildup, and minor roots. Hydro-jetting uses high-pressure water to remove grease, sludge, and scale from inside the pipe. After inspecting your plumbing system, we’ll recommend the safest and most effective solution for your situation.
How do I know if it is a main line clog or just one drain?
If only one sink, shower, or tub is draining slowly, the problem is usually isolated to that fixture. When several drains back up at once, or toilets gurgle while appliances are running, you may have a main sewer line blockage. Stop using water and contact a plumber as soon as possible.
Is the homeowner responsible for a sewer lateral clog, or is it the City of Longmont?
In most cases, homeowners are responsible for the sewer lateral that runs from the home to the city’s main sewer connection. The City of Longmont maintains the public sewer main beneath the street. If you believe the issue is affecting multiple nearby properties, contact the city’s public utilities department first. If the blockage is in your sewer lateral, we’ll inspect the line and recommend the appropriate solution.
Should I use Drano or chemical drain cleaners?
No. Chemical drain cleaners can damage older pipes and create additional safety concerns during professional repairs. If your drain is slow, avoid using harsh chemicals and have the blockage inspected instead. If water has already leaked into your home, we can also check for hidden plumbing damage during your service visit.
