When a sewage drain tube becomes blocked, air bubbles appear. The bubbles come from a drain and make gurgling sounds. You can see the bubbling when you flush the toilet as well.

It regularly happens for odours to come from the kitchen sink. It is unusual for odours to come from the bathroom sink, shower, or tub. If there is an odour in one or more of these places, there could be a problem with the sewage system itself.

Slower drainage occurs when sewage overflows it. In turn, this increases obstruction. Slow drainage is one of the most typical indications of a sewage clog. It may be a clue that something is obstructing the line and creating the backup if you discover that your sinks, showers, or bathtubs are draining slowly.

To clean it out, you may also try pouring a pot of boiling water down the drain. If it doesn't work, you should contact a plumber right once to take care of the issue. 

Professional plumbers will use a camera to check your sewer or drains to find the issue, and they will then use high-pressure jetting equipment or a drain cleaner to clear it out.

If you notice mould or mildew growing where the pipes are buried behind your walls, you may have a sewage backlog. This is due to the moisture in the backup providing excellent conditions for mould and mildew growth.

It is critical that you act if you see any of these symptoms. The best plan of action is to contact a plumber who can inspect the sewage system and handle the backup.

Since the sewage is backed up and leaking, your yard most likely contains standing water. This is especially typical when there has been a lot of rain or flooding. 

You might also look into the source of the standing water to check whether a sewage line is to blame.

Excessive growth of grass in your garden is another indicator of a sewer blockage. It frequently happens that the sewage backup seeps into the ground and fertilises the vegetation. 

When you notice the grass growing out of control, this is a clue that you can typically locate the spot in your yard where the backup is taking place.

The puddles in your backyard might be the result of a sewer backlog. Opening and checking the sewer cleanout line on your property is a simple approach to getting rid of a minor blockage in a sewer pipe. This pipe can be used to circulate waste to restart the underground water supply.

The sewage cleanout pipe can be in your basement or backyard. Your grass will suffer from divots if the ground near a sewage line backup is soaked with liquid from the leak. The worst-case scenario is that it may actively cause a sinkhole, which might be dangerous if left untreated.

Sewage from a blocked sewer pipe may be used as fertiliser by plants. In rare circumstances, tree roots may even be able to penetrate the sewage pipe's interior by taking advantage of tiny fractures in the pipe.

No matter what, a backup will probably produce plants that are healthier and greener than the rest of the nearby grass.

Pressure caused by sewage backing up in a sewer pipe can harm pool and porch concrete. A sewage line backlog may also be the cause of holes and fractures in your home's concrete foundation; cracks typically signify an issue that has existed for a while.

Rats can access the pipes running behind your walls from the city/mainline tie-in since they dwell in sewers. A typical rat may enter your sanitary sewer through a crack or aperture (around 3/4 inches) and ask you to dinner. 

Numerous deadly illnesses, including the plague and hemorrhagic fever, are spread by rodents.

Being bitten by an infected rodent or merely inhaling dust that has been polluted with rat urine or droppings can spread certain illnesses. An insect infestation might also be a sign of a clogged sewage system. Insects such as cockroaches, palmetto bugs, and sewer flies have a considerably easier time coming into your home through sanitary sewer cracks than rats.

Cockroaches have several detrimental effects on human health because specific proteins (referred to as allergens) present in cockroach excrement, saliva, and body parts can induce allergic responses or provoke asthma symptoms, particularly in youngsters.

Calling a pest control professional on a regular basis can fix the problem momentarily, but if your sewage line is damaged, the pests will never stop coming into your home. You'll need to fix their access location, which might be a breach in your sewage pipes.

A plugged drain is the most frequent cause of this. A clogged drain may be an indication of a sewer issue resulting in sewage backup through your bathtub drain.

There are a few things to watch out for while draining your bathtub. When the water drains slowly after a bath or shower, it is usually the first indication that anything is amiss. Although it's not often a warning of an emergency, this might indicate a blockage.
