The Importance of Sewer Rodding in Chicago

The Importance of Sewer Rodding in Chicago

In a city like Chicago, there are countless systems in place to ensure its smooth functioning. One such vital system is the sewer system. It may not be the most glamorous topic of discussion, but understanding the importance of sewer rodding is crucial for every resident and business owner in Chicago.

The Role of Sewers in Chicago

Before getting into the significance of sewer rodding, let’s first explore the role of sewers in Chicago. The sewer system is responsible for transporting wastewater and stormwater away from homes, businesses, and streets. It plays a critical role in maintaining public health, preventing flooding, and preserving the environment.

Chicago’s sewer system is an intricate network of underground pipes that span for miles and connect to treatment plants. These pipes collect and carry wastewater from toilets, sinks, showers, and other sources to ensure it is properly treated and disposed of. Additionally, the storm sewers collect rainwater and runoff to prevent water accumulation on the streets, reducing the risk of floods.

The Importance of Sewer Rodding

Sewer rodding, also known as drain rodding or rooter service, is a maintenance procedure that involves clearing the sewer lines of any obstructions or blockages. It is a preventative measure that aims to keep your home sewer system functioning optimally. Here are several reasons why sewer rodding is of utmost importance in Chicago:

Preventing Blockages and Backups

Over time, debris, grease, tree roots, and other foreign objects can accumulate in the sewer lines, leading to blockages. If left unaddressed, these blockages can cause sewage backups, which can result in property damage, health hazards, and significant disruptions. Regular sewer line rodding helps prevent these blockages, ensuring the smooth flow of wastewater and stormwater.

Maintaining Public Health

A properly functioning sewer system is critical for safeguarding public health. When sewer lines are blocked or compromised, wastewater can overflow into your home or business. This can contaminate the environment, exposing residents to harmful bacteria, viruses, and other pathogens. By having your sewer line rodded out, the risk of sewage backup and potential health hazards is significantly reduced.

Minimizing Flooding Risks

Chicago is no stranger to heavy rainfall, and inadequate sewer maintenance can exacerbate the risk of flooding. When storm sewers are clogged with debris and sediment, rainwater cannot efficiently drain away, leading to streets and neighborhoods being inundated. Routine sewer rodding helps keep the sewer system clear, allowing rainwater to flow freely and minimize the chances of flooding.

Extending the Lifespan of Sewer Pipes

Regular sewer rodding helps extend the lifespan of sewer pipes. When blockages occur, the pressure within the pipes increases, potentially causing them to crack or burst. These pipe failures can be costly to repair and may require extensive excavation. By proactively clearing sewer lines, the stress on the pipes is reduced, contributing to their longevity and minimizing the need for costly repairs or replacements.

Seek Professional Assistance

When it comes to sewer rodding, it is highly recommended to seek the services of a professional plumber in Chicago. Trained technicians have the knowledge, skills, and specialized equipment necessary to safely and effectively clear sewer lines. Attempting to perform a drain rodding without proper expertise can result in further damage or incomplete blockage removal.

Regular Maintenance Schedule

Establishing a regular maintenance schedule is key to preventing sewer issues. By scheduling periodic drain rodding services, you can proactively identify and address any potential blockages or obstructions before they escalate into major problems. The frequency of sewer rodding may vary depending on factors such as the age of the sewer system, the number of users, and the surrounding environment.

Use High-Quality Equipment

Professional plumbers utilize specialized sewer rodding equipment designed to effectively remove blockages without causing damage to the pipes. These tools, such as high-pressure hydro jetting service and mechanical rodding machines, ensure thorough cleaning while preserving the integrity of the sewer lines. Investing in high-quality equipment guarantees the best results and reduces the risk of complications.

Consider Preventative Measures

In addition to sewer rodding, implementing preventative measures can further enhance the functionality and longevity of the sewer system. Regularly inspecting sewer pipes, installing backflow valves, and educating residents about proper disposal practices can help minimize the occurrence of blockages and sewage backups.

While sewer rodding may not be the most glamorous topic, it holds immense importance in maintaining Chicago’s sewer system’s efficiency and preventing issues such as blockages, backups, and flooding. By understanding the significance of drain rodding and following best practices, both residents and business owners can contribute to the overall well being of the city while ensuring the longevity of the sewer infrastructure.

Sewer Back Up Causes and Quick Fixes

Sewer Back Up Causes and Quick Fixes

The sewer system is necessary for urban infrastructure because it helps maintain a healthy and safe environment. Carrying away wastewater helps keep the environment secure from flooding and helps stop the spread of water-borne diseases. Therefore, it could be troublesome if a sewer backup is in your home.   

The sewage system is a vital component of your commercial building since it is responsible for adequately disposing of wastewater away from the property. By strategically discarding waste, it is crucial to keep it well-maintained to avoid issues affecting its functionality. 

Although the primary function of a sewer is to circulate wastewater, a commercial system is complex and requires maintenance and professional services. Installing plastic access doors and panels will allow convenient access to these critical fixtures whenever there is a need for repairs and maintenance. 

But what are the common causes of backed-up sewers, and what can we do to fix and prevent it from happening again? Keep on reading to find out more!  

Cause #1 Clogs or Blockages  

Does your sink drain water slowly? Are there unfamiliar gurgling noises when you flush the toilet? These common signs could indicate clogged drains. Clogs mainly develop over time and are a product of a blockage that restricts the water flow from your drainpipes, impacting the plumbing throughout your entire home or establishment.   

Clogged drains can affect multiple fixtures such as sinks, toilets, showers, bathtubs, and sprinkler systems. Raw sewage could travel back into your drainpipes and your plumbing fixtures from the septic tank or the main sewer lines if the clogs become severe. The situation can get messy, and you would want to contact a plumber right away for professional hydro jetting service.

Drain clogs are usually a long process of material buildup in your drains. Here are some of the common materials that can clog your pipes: 

  • Hair  
  • Solidified grease  
  • Baby wipes and feminine hygiene products  
  • Extra-thick toilet paper, facial tissues, towels, and other wiping products.   
  • Dental floss and cotton swabs  
  • Products labeled non-flushable 

You can place a drain strainer in your bathroom drains or sinks to prevent materials from falling into your drainpipes to prevent clogs from occurring. Also, make sure to dispose of hygienic products properly and, as much as possible, minimize the amount of toilet paper that you flush down your toilet.  

Cause #2 Tree Roots  

Tree root invasion happens when trees roots penetrate your sewage lines, growing through your plumbing pipes or crawling around and crushing the lines, searching for the water that flows inside.  

The tree root invasion process is usually slow, but it could speed up if your lines are in bad condition, with holes or cracks that conveniently allow the roots to enter the drain. 

To prevent yourself from dealing with this situation, you should estimate the suitable area if you’re planning to plant a tree within your property. It will vary depending on the type of plant and its growth rate. Ensure that the site you choose will not interfere with your plumbing pipes.  

Cause #3 Main Sewer Line Blockage 

A blockage in your sewer system usually occurs in the main sewer line owned and maintained by your city. The sudden backup caused by a clog is similar to what you experience during a household blockage. It can also be due to insufficient design capacity if your area encounters serious growth.  

The problem becomes prominent if a community has difficulties with the sewers after heavy rainfall. The main sewer blockage will continuously affect your plumbing in the entire house or establishment, rather than affecting just one drain.   

To decrease the damage, once there is a block in your main sewer line, shut off all water supplies in your home or establishment and shield drain openings with material that can absorb the liquid.  

Final Thoughts 

Although these valuable tips are practical and helpful, you should immediately contact a professional sewer line cleaning service if nothing changes. There could potentially be a more severe cause for the blockage, which would require a possible sewer line repair or replacement. 

Why Hydro Jetting is Important Before a Sewer Line Repair

The sewer lines in your home are designed to last a long time. It is not uncommon to find fully functional sewer lines that are twenty years old and over. This is because sewer systems, due to the type of content that passes through them, are designed to be sturdy.

Why Hydro-Jetting is Important Before a Sewer Line Repair

However, even the most well built sewer line will eventually have problems. These issues can come from several sources. The sewer line in your home can get damaged because of misuse, warns Jilsa Management. Or it can lose some of its function through wear and tear or a natural accident.

Regardless of the origin of the issues in your sewer lines, you want to solve the problem and make sure it does not return. To get this result, you should know the best practice for fixing a damaged sewer line; the sewer line repair should be preceded by hydro-jetting.

What is hydro-jetting? What does it do? And why is hydro-jetting important during sewer line repair?

What Is hydro-jetting?

Hydro-jetting is a drain cleaning method that uses high-pressure water to blast away clogs and blockages inside the sewer lines. Water is delivered at a pressure of up to 6000 PSI, which is enough force to remove tree roots, sludge, and other materials lodged inside the pipes.

The process of hydro-jetting is as follows:

  1. As a first step, the plumber conducts a sewer camera inspection by installing a small camera on one end of a cable and inserting it into the sewer line.
  2. The camera travels through the sewer line and sends back images of the interior of the pipes to a computer screen monitored by the plumber.
  3. This initial process helps the plumber pinpoint the location of the problem and determine its severity. The inspection also tells the plumber if it is safe to go on with the next step.
  4. If it is safe to proceed – that is, there is no possibility of the sewer line collapsing – the actual hydro-jetting process can now begin.
  5. Hydro-jetting equipment consists of a large tank filled with water, a specialized high-pressure water hose, a super-strong nozzle, and equipment for pushing the water through the nozzle at high pressure.
  6. The high-pressure water hose, with the nozzle at its head, is inserted into the sewer line until it reaches the point of the blockage.
  7. The clog is blasted with just enough water pressure to break up the obstruction inside the pipe. Hydro-jetting can deliver enough water pressure to shear away plant roots.
  8. The dislodged material is washed down the pipe and into the city’s main sewer lines.
  9. Finally, another sewer camera inspection is done to view the results of the process and determine the condition of the pipes.

Hydro-jetting lets your plumber clear blockages inside the pipes without digging up the yard or exposing your pipes to the risk of damage. Hydro-jetting can be used to effectively remove the following kinds of blockage from a sewer line.

  • Sludge or grease, fat, and oil build: When you flush grease, fats, and oil into the drain, these materials cling to the sides of the pipes and trap dirt. A hydro jet will remove buildup.
  • Intruding tree roots:  In a bid to find water and nutrients, the roots of nearby shrubs or trees can find their way into the sewer line. Hydro-jetting will solve this problem.
  • Pipe scale: Dissolved minerals in hard water are deposited on the interior surface of pipes, where they reduce the diameter of the pipe. Hydro-jetting will remove pipe scale.
  • Non-flushable objects: A range of items we use in the home find their way into the sewer line. Hydro-jetting can blast away these troublesome items.

Hydro-jetting is a powerful yet gentle method for cleaning drains. But why is it necessary to carry out this procedure before a sewer line repair service?

Why hydro-jetting is done before sewer line repair

  • To detect problems: Hydro-jetting the sewer line washes away the layers of filth inside the sewer line and exposes the actual surface of the pipes. This allows the plumber to see the true extent of the damage to the sewer line.
  • Improves the accuracy of repairs: By combining sewer camera inspection with hydro-jetting, the plumber can pinpoint the location of a problem. Hydro-jetting injects a high level of accuracy into sewer repair. It ensures the finished job is well done and long- lasting.
  • Reduce costs: There are other ways to clean a sewer line before it is repaired, but hydro-jetting is the quickest and most-effective method. Other methods will cost more in labor and time.

Improves sanitation and indoor air quality: Hydro-jetting the sewer before repairing helps the plumber do a more complete job. Hydro-jetting gets rid of the bacteria inside the drain that cause bad odors. Unless the sewer line is cleaned with a hydro-jet, the bacteria inside them are not easily removed.
