What Happens Inside Your Pipes During Drain Cleaning?

Clogged pipes in your home aren’t just an inconvenience. If the problem is left unresolved, you can end up with wastewater backups, persistent foul odors, and slow draining. Though it’s a good idea to start the drain cleaning process with a plunger or drain snake, these techniques do not always work. When DIY techniques fail to clear the clog, it’s best to call a local plumber for professional help.

But what happens inside your pipes during drain cleaning? This is a common question among property owners when they need help with cleaning clogged drains. Our plumbers at Mr. Rooter Plumbing are here to help you understand the process inside and out.

For over 20 years, we’ve seen it all, and our hands-on experience allows us to quickly identify the causes of drain clogs and provide the right solutions. The next time you encounter a drain clog and need a skilled plumber to handle the situation, look no further than Mr. Rooter Plumbing. In this post, we’ll explain how drain cleaning works to help you understand what happens inside the pipes during the process.

  • Initial Camera Inspection

A typical drain cleaning job begins with a camera inspection, whereby a plumber in Coraopolis inserts a specialized camera into the drain line.

This step is important to accurately identify the cause, location, and severity of the blockage. A professional plumber uses specialized cameras to view the interior of the affected pipes. Rather than relying on guesswork, the experts are able to distinguish between simple clogs, tree root intrusion, and structural damage.

An initial camera inspection allows the plumber to know the pipe’s condition, identify the exact location of the clog, and detect hidden structural problems. If you’ve been plunging your drains with no success, you may be dealing with pipe damage or tree root intrusion. It’s a good idea to seek help from a trusted plumber that specializes in drain cleaning.

  • Breaking Apart the Blockage

Once the issue is identified, the drain cleaning process begins. Depending on the severity of the clog, a plumbing service may use tools such as drain augers (also called plumbing snakes) or hydro-jetting equipment.

A drain auger is designed to break through clogs and pull out debris that is blocking the pipe. The rotating cable moves through the drain and cuts or grabs materials like hair and grease buildup. This process creates a path for water to flow again.

For more severe buildup, your plumbing service may recommend hydro-jetting. This drain cleaning solution involves sending a powerful stream of high-pressure water through the pipes. The force of the water scrubs the pipe walls and flushes away grease, sludge, soap residue, and other debris that has accumulated over time.

  • Flushing Out the Debris

As the clog breaks apart, the debris begins to move through the drain line. Water pressure helps flush the loosened material out of the pipes and into the sewer line. During this stage, the pipe interior becomes cleaner, allowing water to flow freely again.

In cases where hydro-jetting is used, the pressurized water also removes stubborn buildup that may not have been fully blocking the pipe but was gradually restricting flow. This thorough cleaning helps restore the pipe’s original capacity. Remember, hydro-jetting should be handled by a dependable plumbing service to ensure the process is done safely. The high-pressure water can damage weak pipes or even cause injury in case
