Drain & sewer cleaning is the process of removing blockages, buildup, and debris from your home's pipes — from the small drains in your sinks and showers all the way to the main sewer line that connects your home to the city system.
Quick answer — what is drain and sewer cleaning?
A slow drain might seem like a minor annoyance — but it can be your plumbing system's first warning sign of a much bigger problem. Left alone, a partial clog becomes a full backup. A full backup can mean sewage in your basement, damaged pipes, or a costly excavation job.
That's why understanding how your drainage system works — and knowing when to call a pro — can save you thousands of dollars and a lot of stress.
At iRepair Heating & Air, we've helped homeowners across the Salt Lake area tackle everything from stubborn kitchen clogs to full sewer line backups, bringing the same fast, honest service to drain & sewer cleaning that we apply to every job. Read on for a complete breakdown of everything you need to know, from causes and warning signs to the tools professionals use and how often you should schedule service.
Drain & sewer cleaning terms made easy:
Every time you flush a toilet, run the dishwasher, or take a shower, wastewater flows out of your living spaces and down into a complex web of pipes. To keep this system running smoothly, you need to understand how these pipes are structured and how they are maintained.
Your home's drainage network starts with the small, visible branch lines connected to your sinks, tubs, and toilets. These branch lines typically have a smaller pipe diameter, ranging from 1.5 to 3 inches. They carry wastewater to your main sewer line, which is a larger pipe (usually 4 to 6 inches in diameter) buried underground beneath your property. This mainline is the single highway that transports all waste away from your home and into the municipal sewer system or your private septic tank.
When a clog occurs in a branch line, it only affects one fixture. For example, a hair clog in your master shower won't stop your kitchen sink from draining. However, when a blockage forms in the sewer mainline, it acts like a traffic jam on the freeway—nothing can get past it, causing wastewater from all over the house to back up into the lowest drains in your home.
Maintaining these systems requires specialized knowledge and heavy-duty professional plumbing equipment. If you want to dive deep into how these systems are structured and cleared, check out The Ultimate Guide to Cleaning a Blocked Drain Line.
Many homeowners use the terms "clearing" and "cleaning" interchangeably, but in the plumbing world, they describe two very different levels of service.
Drain clearing is a reactive, temporary fix. When a plumber clears a drain, their primary goal is simply to restore flow. They typically use a mechanical snake (also known as a cable machine or drain auger) to punch a hole through the physical obstruction. While this gets the water moving again, it often leaves a thick layer of grease, soap scum, or mineral scale clinging to the pipe walls. It is only a matter of time before debris catches on that remaining buildup and forms another clog.
Full drain & sewer cleaning is a restorative, comprehensive process. Instead of just poking a hole in a clog, professional cleaning restores the pipe's interior to near-original diameter. This is achieved using advanced techniques like hydro jetting, which blasts the entire interior surface of the pipe with high-pressure water.
Here is a quick look at how these two approaches compare:
| Feature | Drain Clearing | Full Drain & Sewer Cleaning |
|---|---|---|
| Primary Tool | Mechanical Snaking / Cable Machine | High-Pressure Hydro Jetting |
| Goal | Restore temporary flow by punching a hole | Restore full pipe diameter and clean walls |
| Buildup Removal | Leaves grease, scale, and scum on walls | Scours away 100% of grease, scale, and scum |
| Longevity | Short-term relief (clogs often return quickly) | Long-term results (often lasts 1 to 5 years) |
| Best For | Simple, one-time physical obstructions | Recurring clogs, heavy grease, and root removal |
While a simple clearing might cost less upfront, a complete cleaning is often the most cost-effective choice in the long run because it prevents repeat service calls. To understand the financial breakdown of these services, you can read about The Real Cost to Clear a Blocked Drain.
You shouldn't wait for a major sewage backup to think about your pipes. Proactive, preventive maintenance is the key to avoiding plumbing disasters.
As a general rule of thumb, most residential properties benefit from a professional drain cleaning and annual inspection every 18 to 24 months. However, the ideal frequency depends heavily on several factors:
For those living in unique mountain climates, seasonal shifts can also impact your plumbing. Be sure to review Jetting and Maintenance Tips for Park City Homeowners to keep your mountain home flowing smoothly year-round.
Clogs rarely happen overnight. Most blockages are the result of weeks, months, or even years of gradual accumulation. Understanding what goes down your drains can help you prevent major backups. If you are currently dealing with a sluggish pipe, scheduling a professional drain clearing in Salt Lake City is the fastest way to get things flowing again.
The most common culprits behind residential and commercial drain blockages include:
If you live in an established neighborhood with beautiful, mature trees, your sewer line is constantly under threat. Tree roots are highly sensitive to moisture and nutrients. Because older sewer pipes made of clay or cast iron have seams every few feet, warm water vapor escapes into the surrounding soil.
Seeking out this moisture, microscopic tree roots slip through tiny structural cracks or loose joints in the pipes. Once inside, they feast on the nutrient-rich wastewater, growing into massive, woody root balls that act as a perfect net for toilet paper and solid waste.
As these roots grow, they exert incredible pressure on the pipe walls, eventually causing the pipe to collapse or belly (sag). Addressing this requires heavy-duty root-cutting equipment and professional expertise. Learn more about protecting your older lines by reading Why Your Pipes Need a Park City Drain Cleaning Service.
In kitchen drains, the absolute worst offender is FOG: Fats, Oils, and Grease.
When you pour warm grease down the kitchen sink, it looks like a harmless liquid. But as soon as it hits the cold underground pipes, it cools, solidifies, and clings to the pipe walls. Over time, food particles from your garbage disposal get trapped in this sticky grease, forming a concrete-like barrier.
This issue is amplified in commercial kitchens and restaurants, which handle massive volumes of grease daily. Without routine grease trap pumping and professional line jetting, commercial kitchen drains will quickly ground a business to a halt.
When a sink starts filling with water, many homeowners run to the nearest hardware store for a quick fix. While a plunger or a cheap plastic drain zipper can occasionally clear a shallow hair clog in a bathroom sink, DIY methods fall short for deep, stubborn, or recurring blockages.

Those bright bottles of liquid drain cleaner on supermarket shelves promise a cheap, instant fix. In reality, they are incredibly dangerous for both your plumbing and your family.
Most chemical drain cleaners rely on highly caustic ingredients like sulfuric acid or sodium hydroxide. These chemicals work by generating intense heat to melt away grease and hair. Unfortunately, this chemical reaction does not distinguish between a clog and your plumbing:
Instead of risking your pipes, look into safer alternatives discussed in our guide on the Top 5 Drain Cleaners to Save Your Sewer Line.
Professional plumbers don't guess what is causing your clog—they use advanced technology to pinpoint the exact issue and clear it safely.
First, a professional technician will perform a waterproof camera inspection. By feeding a high-resolution, flexible camera down the line, they can see exactly what is causing the blockage, whether it is a toy, a thick wall of grease, or a tree root. This allows them to choose the perfect tool for the job.
For tough blockages, professionals use:

Yes, but only when performed by a licensed professional who conducts a pre-inspection camera run first.
If your older clay or cast iron pipes are structurally sound, hydro jetting is actually the safest and most effective way to remove scale and roots. Because it uses 100% water and no harsh chemicals, it won't corrode the metal. However, if the camera inspection reveals that the pipe is severely cracked, rusted thin, or collapsed, hydro jetting could destroy the remaining pipe. In those cases, pipe repair or replacement is required before any high-pressure cleaning can take place.
