Let’s first talk what sewer backups are for those who are not familiar with this plumbing issue. A sewer backup is when sewage wastes return to the house’s plumbing such as the drains and even the basement. The main reason why a sewer backup happens is because the sewer pipes are heavily clogged; so whenever there is a strong rain shower, the sewer pipes can easily overflow and go back up to the internal plumbing of the household. Take note of the tips that will be presented below since it’s focused on sewer backup preventions.


  1. Place a standpipe

This is actually just a normal pipe but it’s customised to help control the overflow of the sewer or pipes. The pipe is placed in the floor drains and is enclosed by watertight rubber seal. If ever there is an overflow of sewer wastes or water then it won’t spill on the floor since it will go directly into the added pipe. However, the pipe might not be able to accommodate a large influx of wastewater so there’s still a chance of an overflow.

  1. Installing a backwater valve or backflow prevention valve

There are some situations in which the sewer backup is not caused by clogs but by the sudden change of pressure. There is actually a standard pressure for the wastewater for closed sewer systems. Whenever there is an irregularity with the pressure then the wastewater and sewage wastes push back into the house. To prevent the return of these sewer wastes, you need to have a backflow prevention valve installed in your sewer system. You can’t install this device on your own since it actually requires a permit and of course a qualified and licensed plumber. Backflow prevention valves are mostly used for closed sewer systems since these systems only have a one-way outlet.

  1. Drain plugs

This is the most practical among the solutions in this article. Drain plug devices is installed underneath the drains and block any sewage backup or flood. If there is no more sewage waste build-up then it will return to normal and allow water to enter the drains again. It’s important to make sure that the float device of the drain plug is working since this will trigger the device to work.

  1. Keeping the sewer pipes clear

Sewer clogs are the number one reason why households experience sewer backup. There are many possible reasons why a sewer main line is clogged such as: root blockage, various wastes accumulation, collapsed pipes, and many more. The only way to know the exact cause of the clog is to check the insides of the pipes. There are a lot of plumbing services that offer sewer pipe examinations so you can just call the said services. After the complete evaluation by the plumbers they will be able to advise solutions for you.

  1. Installing an overhead sewer

You’ll be guaranteed that you won’t have any sewage backup if you install an overhead sewer. The sewage or water overflow with the sump and moved to the overhead pipes. This is actually a very costly but highly effective solution. Just like the backflow prevention valve; installing an overhead sewer needs a permit and must be installed by a licensed plumber.
