Why Your Sewer Lines Are Getting Clogged?- Top 4 Reasons

Like most householders, you don’t think about your home’s plumbing condition until there’s a problem. This can lead to expensvie fees and long days of being unable to use your plumbing fixtures. Among the most prevalent complications people tend to deal withis a clogged sewer line. 

Not sure what’s causing all these clogs? Here are the top four reasons to identify the best sewer repair solution for your home:

1. Sagged Sewer Line

Over time, your sewer lines may begin to sag. This is precipitated by several circumstances, including the weight of the soil above the pipes, the type of pipe material, and the amount of water flowing through the pipes. 

Sewer line sagging can cause problems, including decreased water flow, blockages, and overflows. In severe cases, it can indeed lead to sewage backups into your home. 

If you notice your sewer lines beginning to sag, it’s essential to request sewer repair as soon as possible. Otherwise, you may be faced with costly repairs down the road.

2. Improper Flush Usage

Your sewer lines are designed to handle a certain amount of waste and water flow. When you flush oversized items down the toilet, it causes an increase in water flow. The additional water volume and weight of the washed item stress your sewer line pipes and cause them to crush or crack. 

Additionally, the flushed item can become stuck in the pipe, causing a blockage that prevents wastewater from flowing freely through your sewer line. If the jam is intense enough, it can cause your sewer line to back up into your home, leading to costly repairs. 

3. Growth of Tree Roots

If you’ve noticed that your sewer lines are becoming clogged more frequently, it’s likely because tree roots have begun growing in the bar. This is a common dilemma in older homes, as tree roots can slowly work their way into even the most minor cracks and fissures. 

Once they’ve gained access to the sewer line, they continue to grow and expand, eventually causing a complete blockage. Not merely is this a nuisance, but it can also lead to expensive repairs. 

Fortunately, you can do a few things to prevent tree roots from growing in your sewer line. 

Make sure that all trees on your property are properly trimmed and pruned. This will help to discourage root growth in the first place. 

Then, have your sewer line regularly inspected for any potential problems. If tree roots are already present, they can be removed before they cause any severe damage. 

4. Jetting Grease on Drain

Sewer lines are constructed to carry wastewater away from your home or business. Grease, fats, and oils can build up on the walls of your sewer line, gradually narrowing the opening until it becomes completely clogged. 

When this happens, sewage can go back into your home or business, causing a nasty mess. Pouring hot water down the drain may seem like a quick fix, but it can make the problem worse by melting the grease and allowing it to solidify further downstream. 

The best way to avoid a clogged sewer line is to dispose of grease in the trash instead of spilling it down the drain.
