Top 4 Reasons for Sewer Line Clogs

A properly functioning sewer line is crucial for maintaining a clean and efficient plumbing system. However, clogs in the sewer line can cause significant problems, including slow drains, unpleasant odors, and even sewage backups. As experienced plumbers in Peoria, Rooter Hero Plumbing & Air of Phoenix has seen and resolved numerous sewer line clogs. Understanding what causes these clogs can help you prevent costly repairs and keep your plumbing system in top shape. Here are the top four reasons why sewer lines get clogged and what you can do about them.

Top 4 Reasons for Sewer Line Clogs

1. Tree Root Intrusion

One of the most common and troublesome causes of sewer line clogs is tree root intrusion. Over time, tree roots grow towards sources of moisture, and your sewer line provides a prime target. If there are even small cracks or leaks in the pipes, tree roots can penetrate and expand inside, creating severe blockages. This not only disrupts the flow of wastewater but can also lead to pipe damage.

Signs of Tree Root Intrusion:

• Gurgling sounds from toilets or drains

• Slow draining sinks and bathtubs

• Frequent clogs despite attempts to clear them

• Sewage backups in multiple drains

Prevention and Solution:

To prevent tree roots from infiltrating your sewer line, avoid planting large trees near your plumbing system. If you suspect roots have already invaded, professional hydro jetting or root removal services from Rooter Hero Plumbing & Air of Phoenix can clear the obstruction. In severe cases, pipe lining or pipe replacement may be necessary to restore your sewer system’s integrity.

2. Grease and Fat Build-Up

Another major culprit behind sewer line clogs is grease and fat accumulation. Many homeowners unknowingly contribute to this issue by pouring cooking grease, oil, and fat down the drain. While these substances may go down as a liquid, they solidify inside the pipes as they cool. Over time, the buildup restricts water flow and eventually leads to complete blockages.

Signs of Grease Build-Up:

• Slow-draining kitchen sinks

• Frequent clogs in the kitchen drain

• Foul odors coming from drains

• Water backing up when using the dishwasher or sink

Prevention and Solution:

To prevent grease-related clogs, never pour grease or oil down the drain. Instead, collect used cooking oil in a container and dispose of it properly. If you’re already facing a grease clog, professional drain cleaning services from trusted plumbers in Peoria can help restore proper flow. Hydro jetting is an effective method for breaking down stubborn grease buildup and flushing it out of the system.

3. Foreign Objects and Debris

Flushing or washing down inappropriate items is another frequent cause of sewer line blockages. Items such as paper towels, baby wipes, hygiene products, hair, and food scraps can accumulate and restrict the flow of wastewater. Unlike toilet paper, which is designed to break down quickly, many of these objects do not decompose easily and can create serious plumbing issues.

Common Foreign Objects Causing Clogs:

• “Flushable” wipes (which are often not truly flushable)

• Feminine hygiene products

• Paper towels and napkins

• Dental floss and cotton swabs

• Small toys or foreign objects accidentally flushed

Prevention and Solution:

To avoid sewer line clogs caused by foreign objects, only flush human waste and toilet paper. For kitchens, use a sink strainer to catch food debris, and never wash down large particles. If a foreign object is already causing a blockage, a professional plumbing service can use specialized tools such as drain snakes or hydro jetting to safely remove the obstruction.

4. Pipe Deterioration and Collapses

Aging or damaged pipes are another major factor contributing to sewer line clogs. Over time, pipes can crack, corrode, or collapse, leading to obstructions and poor drainage. This is especially common in older homes where clay or cast-iron pipes were originally used. When these pipes deteriorate, soil and debris can enter the sewer line, restricting wastewater flow and eventually causing a complete blockage.

Signs of Pipe Deterioration:

• Frequent sewer backups

• Unexplained patches of lush green grass in the yard (indicating leaks)

• Visible cracks or sinkholes near your sewer line

• Persistent foul odors from drains

Prevention and Solution:

Regular plumbing inspections can help detect signs of pipe deterioration before they lead to major problems. If your pipes are old or damaged, trenchless pipe repair or replacement may be necessary. At Rooter Hero Plumbing & Air of Phoenix, we offer advanced sewer line repair techniques that minimize disruption while restoring your plumbing system.

How to Prevent Sewer Line Clogs

While some sewer line issues are inevitable, proper maintenance and awareness can help reduce the risk of severe clogs. Here are some tips to keep your plumbing system running smoothly:

• Schedule regular plumbing inspections to detect potential issues early.

• Avoid flushing non-degradable items like wipes, paper towels, and hygiene products.

• Properly dispose of grease and food waste to prevent buildup in your pipes.

• Monitor tree roots near your sewer line and remove invasive plants if necessary.

• Invest in professional drain cleaning services to keep your sewer line clear.
