Why Do My Drains Back Up After It Rains?

Causes of Blocked Drains

Clogged drains are a common issue for homeowners, and wet weather can make it worse. After a rainstorm, water from both the outdoors and indoors can consume available drain space, leading to backups. There are a few common causes of this problem that homeowners should recognize in order to carry out proper maintenance and prevent blockages in the future.

The first factor is organic debris. Leaves, dirt, grass clippings, and other organic materials can accumulate in your yard, clog pipes, and cause a backup when they get wet. Even though the material may seem small, it can easily block up pipes if it isn’t cleared out.

Another common problem is grease, oil, and fats. These substances adhere to the inside of your pipes and gather, even in small amounts. When wet weather arrives, they can loosen, gather together, and create a blockage.

In addition, roots from trees and shrubs can invade pipes and cause backups. Roots are attracted to the moisture inside of pipes and, over time, can cause deterioration and clogs.

Finally, improper plumbing systems can canalize the rainwater and overflow into your drains. This can cause serious backups when the entire system can’t handle the amount of water in use.

Storm Drain Maintenance

In order to prevent and reduce the risk of blocked drains, it’s important to take care of your storm drain system. Regular maintenance and proper use of your storm drain will help ensure it is working as effectively as possible.

When it comes to maintenance, it’s important to keep all outdoor drains and gutters clear, as well as to check regularly for any dirt, debris, or build–up. You should also check your outdoor drains for any signs of infiltration or decay. If you see any root activity around the pipes, contact a professional to clear out the roots.

Inside your home, be sure to avoid pouring any grease or oil down the drain, and scrape food items off of dishes and utensils before washing. It’s also important to inspect your indoor pipes regularly to check for any corrosion or obstructions.

Rainwater Collection

In addition to regular maintenance, homeowners may also consider installing a rainwater collection system. This system captures rainfall and diverts it away from your pipes, preventing blockages and backups.

Rainwater collection systems can be as simple as setting up a rain barrel or investing in a more complex system, such as a rain garden. The most important part of a rainwater collection system is that the diverted water is directed away from the drainage system and into a separate outlet.

This type of system can be beneficial in both the short– and long–term, as it prevents backups and also helps to save water. In the long run, this can pay off financially in the form of lowered water bills and diverted maintenance costs.

Ultimately, understanding why your drains back up after a rainstorm can help you better manage your storm drainage system. Proper maintenance and rainwater collection are important tools to help you prevent clogged drains and keep your plumbing system running efficiently.
