 Types Of Main Sewer Line Blockages

Soft Blockage

Types Of Main Sewer Line Blockages

Plumbers Near Me

When a plumber explains you had a soft blockage, they are referring to the toilet paper or waste that goes down your sewer line that got stuck. Usually, this shouldn’t happen; however, depending on the condition of the sewer line, regular waste and products can become stuck.

If your sewer line is cast iron, the buildup could be the reason for the blockage. Running a plumbers snake will only temporarily clear the blockage, but the problem will continue. Cast iron is a durable material but will corrode over time. As the pipe corrodes, it becomes jagged and closes in on itself. As waste and toilet paper run down the sewer line, it can get caught on the rough pipe. When this happens, it creates a domino effect and plugs up the sewer line.


How to Fix

Cast iron pipes need to be cleaned regularly and descaled. This process either involves a hydro-jetting or even better a descaling chain that removes debris from cast iron.


Hard Blockage

A hard blockage is when you have roots or something similar that is causing the pipe to stop the flow of sewage. Roots are by far the most common reason is they will break through pipes and keep growing in the sewer. Again, just like a soft blockage, there is a reason why there is a blockage but usually more major.

Failure to address the issue of the hard blockage will result in more sewer backups. To pinpoint the problem, a plumber can perform a camera inspection and determine the exact cause and location of the problem.


How to Fix

Once a plumber has identified the specific problem, repair recommendations can be made. In most cases, many recommend that if the damage to the sewer pipe isn’t too significant, a lining can be installed to reline the pipe underground. This can be expensive but still much cheaper than digging up the sewer pipe and replacing it.

Grease Blockage

Grease is one of the worst things that you can pour down your drains. Grease when it cools down hardens and will block your sewer from flowing correctly. Even small amounts of grease mixed with water can grasp ahold of the inner parts of your pipes and form buildup. It is best that you and the other household members never pour grease down your sink and drains. Many people that use grease for cooking pour the excess grease into a container with a lid like an empty water bottle or old jar. Then the entire container can be thrown out into the garbage instead of clogging up your sewer drains.


How to Fix

If your sewer system is blocked up by the only grease, it is possible you can have your sewer line hydro jetted. This process uses a large machine that has extremely high water pressure to descale the inside of the sewer pipe. This plumbing procedure is much more cost-effective than having to have your pipes replaced.


Foreign Objects

It may surprise you that a good number of calls that plumbers go-to for blockages are foreign objects lodged in the sewer line. This isn’t the usual baby wipes or toilet paper that plumbers find but instead household items that seem to find their way down the toilet and into the sewer line. Children are often the culprits of these causes as some seem to find it interesting to flush their toys or other household items down the toilet. If a homeowner is lucky, the foreign object will lodge in the bathroom itself. If they aren’t as fortunate, the thing will make its way into the sewer drain line where it can get stuck. Often in these cases, a plumbers snake may not work to clear the blockage.


How to Fix

The first step is to have a plumber come out and see where the foreign object is located at. If it’s in the toilet, the plumber may be able to pull the toilet and remove the item. If the object made its way to the sewer, than the plumber can try his snake. If the snake doesn’t clear the line, then a video camera inspection should be performed to see where and what the blockage is. Once the location and obstruction are confirmed, a spot repair may be required.


Broken Sewer Pipe

When a sewer pipe breaks, your house will soon back up. Fairly quickly roots will find a way into your sewer pipes, which will clog up the line. Before the roots grow in, you may have other debris that gets in the way. This could include rocks, dirt, burrowing animals, and shifts in the earth.


How to Fix

When a homeowner has a broken pipe, the pipe will need a spot repair. This will involve a plumber digging down to expose the fractured area of the pipe. Once the area is exposed, the section that is broken can be cut out and replaced with new piping.


Recap | Conclusion

Please don’t take it lightly when your sewer backs up. That is generally not normal, and you will want to understand what is going on. In some cases, if you wait too long to make the repairs, it can get more expensive to fix over time as the damage gets worse.
