Although sewer lines are not visible to us, they offer a valuable service to homeowners by removing waste from the home. However, when any of them stops working, we quickly notice that something is wrong that needs to be resolved immediately.

If there are any signs of sewer line problems, you need to pay attention to them and fix them as soon as possible. However, sometimes these signs are not visible until the problems become severe. Therefore, homeowners need to notice the sewer line problems early to fix them at the right time to save your appliances like a home theater or thermostats from the water. Here are some common signs of sewer line problems that homeowners can detect at an early stage.

Old sewer line

Think about the age of your home. If your home was built 20 years ago, your sewer line might need replacement. Sewer lines tend to become more and more fragile with time as they become old and they deteriorate faster. They become more susceptible to cracks and damage. Therefore, it becomes essential to replace the sewer lines in homes that are older than 20 years.


Sewer lines can get clogged like drains. It is one of the most common sewer line problems in homes. The clogging material blocks the flow of wastewater through the pipeline and creates sewage backups in the line. Backups usually apply additional pressure on the pipe, leading to added stress and rupturing the pipes.

Although the clogging in a single line may not cause a severe problem, it can become severe and need immediate attention if it occurs in multiple lines. Therefore, you should call a professional immediately to get the clogged lines fixed in your home. To learn more about sewer line services and repair, visit


Corrosion is a result of an electrochemical reaction that causes the deterioration of walls and metal pipes. The corrosion process leads to thinning of metal pipes and results in a significant reduction in the load-carrying capacity of the line. If corrosion is left untreated, it can lead to multiple leaks, cracks, and ruptures on the pipelines.

Slow Drains

If the water in the sink or bath occasionally drains slowly, it could be a simple blockage and an isolated incident. However, if multiple electrical devices in your home seem to be affected simultaneously, it is a sign that there is a problem with the drainage system, such as the sewer line. If you notice any signs of slow drains in your house, you can call a professional to get the drains checked. Slow drains, if left unattended, can get blocked sooner or later and you don’t want to use swiggy money just because the repair is taking so much time.

Blocking of sewer lines

Clogging and blocking are common sewer line problems characterized by insufficient drainage and increased water in toilets, sinks, bathtubs, etc.

While plumbing can occasionally become clogged, frequent clogs (for example, if sewage builds up with each flush) can indicate problems with the sewer system. In addition, while blockages are not necessarily a cause of alarm, a blockage in more than one drain simultaneously may be worth investigating.

Clogs and clogging related to sewer systems usually start at the lowest level of the house and are usually visible in all installations.

Puddles of water on the lawn

Have you noticed water pooling on the lawn? Water can smell unpleasant and change color. This could be a clear sign that the sewer pipe is broken and needs to be replaced. Untreated wastewater that ends up in the soil can cause significant environmental and health problems.

While you could be experiencing a different problem, the only way to find out what’s going on is to get a professional sewer repair company to inspect your pipe.

Overflowing Toilets

Do all the bathrooms in your home overflow from time to time? Does it happen more often than you would like? You probably have a major problem in the sewer that is causing this nasty incident. For example, roots can grow in sewers, clogging them up. This, in turn, can cause the bathrooms in your home to overflow.

Sudden pest infestation

Another unfortunate side effect of sewer leaks is an unwanted and unexpected increase in pests in and around the home. Rats and cockroaches are particularly attracted to the smell of leaking sewage. In addition to being destructive, these pests can transmit many harmful diseases.

Rotten egg smell

Sewage smells can manifest as the smell of burnt sulfur, rotten eggs, skunk smell, or just plain old sewage. The smell comes from sewage gases that collect in the drains and somehow enter the house. Household sewage gases can be dangerous because they contain hydrogen sulfide, which is toxic in small amounts.

Bad sewage smells do not necessarily mean that the line has been interrupted. Odors are usually caused by a dry or broken seal that allows gas to flow back into the house. In other cases, the problem could be damaged roof ventilation. A plumber can check your seals and openings to see where gas is entering your home.

Gurgling drains

While gurgling can occur in any drain, it is usually first noticed in the bathroom. You may hear a gurgling noise right after you flush, or it may occur if the toilet has not been used recently. Sometimes the gurgle is followed by bubbles in the bowl and the smell of raw sewage.

Gurgling indicates that a blockage is forming in the drain pipe. Often, the blockage is in the affected drain, so all you have to do is clear it. However, in some cases, the obstruction is in the main sewer system.


These are the ten common signs of sewer line problems that every homeowner should know. So, if you notice any of them in your house, you need to contact a professional immediately and get the problems fixed.

Sewer lime problems, if left unattended, can get severe anytime and put the homeowners in trouble. Therefore, homeowners should get these problems fixed as soon as they notice the signs of bad sewer lines in their house.
