A sewer back up can be one of the costliest, messiest and most stressful problems you will ever have to deal with. It is possible that raw sewage can back up into your toilet, sink and bathtub, eventually overflowing into key areas of your house. It’s admittedly a disgusting topic to talk about, but it does happen, and it is important to know how to prevent it. So, here are a few tips on how to clear a mainline blockage:
1. Clear Roots
These are the most common culprits behind sewer backups. Roots belonging to trees and shrubs seek moisture underground and can, therefore, make their way into sewer lines through cracks in the pipe. Typically, they start small but grow and eventually obstruct the line, allowing waste to build up and back up.
Here are some tips on using salt to get rid of such tree roots.
- Obtain 4 pounds of rock salt and flush it down the toilet in the evening before the family goes to bed. That will give the saltwater at least 8 hours in the sewer line. For that duration, do not use any drains in the house to avoid diluting the saltwater.
- After 8 hours, flush the toilet again and resume use of the drains in the house.
- Follow this practice about once or twice a month. Any tree roots in the sewer line will die from the excess of sodium, and the lines will soon be clear.
2. Clear Paper Products
These include such products as paper towels, sanitary towels and diapers that are not intended for flushing. These products aren’t like toilet paper in that they do not disintegrate easily. They can, therefore, block the sewer line and cause a backup. To prevent this from happening, they should not be flushed down the toilet but should instead be thrown in the garbage.
Sanitary towels and diapers should never be flushed down the toilet as they tend to clog the sewer line the fastest. This also includes tampons. All of these should be disposed of in a specialized garbage bin placed next to the toilet, such as the ones in public restrooms.
3. Avoid Putting Grease in Drains
Grease is another culprit that has a way of causing backups. You should avoid, as much as possible, pouring grease down a drain. This also applies to cooking oil as it often has the same effect. Some people believe that using hot water to wash grease down the drain helps. That is not true. The grease will go down the drain more easily, but it will eventually cool off further down the drain and solidify. When it does that, it will clog the drain and cause a backup. The line will have a harder time letting water through and get clogged.
The best solution is to pour the grease into a container that is resistant to heat and let it cool off. You can then dispose of it in the garbage.
