Many homeowners are left wondering why their drains back up when it rains. While they may seem like two unrelated scenarios, the truth is that heavy rainfall can cause it to happen. This article will discuss the causes of sewer backup during heavy rain, signs of sewer backup, if heavy rain can cause plumbing problems, and what homeowners can do to prevent sewer backup during heavy rain.
What Causes Sewer Backup During Heavy Rain?
Overflowing Municipal Sewers
One of the causes of sewer backup during heavy rain is municipal sewer systems overflowing. Municipalities are responsible for maintaining the local sewer system, but when there is a sudden surge of heavy rain, it can cause the system to become overwhelmed. When this occurs, the excess rainwater can cause the sewer system to overflow. When the sewer overflows, water can travel back through lateral lines, causing backups in homes on the street or neighborhood.
Clogged Sewer Line
Another possible cause of sewer backup during heavy rain is a clogged sewer line. Clogs can occur due to a variety of reasons such as tree root intrusion, debris buildup, or other materials getting stuck in the sewer line. When heavy rain occurs, the water that would normally flow through the sewer line has nowhere to go and can cause a backup.
Broken Sewer Pipe
A broken sewer pipe can also cause sewer backup during heavy rain. Age and deterioration of sewer pipes can cause them to break or collapse. When this happens, the water is unable to flow correctly and will cause a backup. Heavy rainfall can worsen the problem and cause more water to enter the broken pipe leading to more backups in the home.
What Are the Signs of Sewer Backup?
Multiple Fixtures Backing Up
One of the signs of sewer backup is when multiple fixtures in your home are backing up at the same time. For example, if both your toilet and shower are backing up simultaneously, this is a clear sign there is a problem with the sewer.
Unpleasant Odors
Unpleasant odors are another sign that you may have a sewer backup problem. If there is a backup in the sewer line, odors can travel back up and waft through the home.
Slow Drainage
Slow drainage is another possible sign of a sewer backup. If several sinks or tubs take longer to drain than usual, it could be stemming from a problem in your sewer line.
Can Heavy Rain Cause Plumbing Problems?
Impact on Sewer and Drainage Systems
Heavy rain can indeed cause plumbing problems. One of the problems that heavy rain can cause is an impact on sewer and drainage systems. As mentioned earlier, heavy rainfall can cause municipal sewer systems to overflow, which can cause backups in homes.
Valve Malfunctions
In addition to overflowing sewers, heavy rain can also cause valve malfunctions. When there is too much rain, valves can become inundated, causing them to fail. When valves fail, it can cause backups in homes.
Clogging and Blockages
Heavy rain can also cause clogging and blockages in plumbing systems. The debris that is washed away in the rainwater can build up and cause clogs in plumbing fixtures or systems.
