Nothing ruins a cozy rainy day faster than a backed-up drain.
You might be enjoying the sound of raindrops against your window, only to step into a puddle in your basement or notice your sinks draining at a snail’s pace.
Unfortunately, heavy rainfall can overwhelm drainage systems, leading to backups, flooding, and potential property damage.
The good news?
You can prevent this nightmare scenario with the right knowledge, some proactive measures, and—in case of damage and emergencies—the help of a reputable drain cleaning company.
Read on to learn how heavy rains cause drain backups and what you can do to keep your home safe and dry.
Why Do Heavy Rains Cause Drain Backups?
Understanding why heavy rain affects your drainage system can help you take the right preventive steps. Here are some common reasons rainstorms lead to drain backups:
1. Overloaded Sewer Systems
Most residential and municipal drainage systems are designed to handle a specific amount of water.
When heavy rain exceeds that capacity, excess water has nowhere to go, causing sewer lines to back up into homes. This may lead to slow drainage, foul odors, and even raw sewage spilling into your home—yikes!
2. Blocked Outdoor Drains
Leaves, dirt, and debris often get washed into storm drains during heavy rainfall. If these drains become clogged, water starts pooling around your home instead of flowing away, increasing the risk of basement flooding and foundation damage.
3. Tree Root Intrusion
Up to 50% of pipe and sewer line damage is caused by tree root intrusion. During extended wet weather, tree roots seek out additional moisture. If your sewer lines have even the tiniest crack, roots can sneak in and expand, causing significant blockages that worsen during rainstorms.
4. Poorly Maintained Drainage Systems
Over time, household drains accumulate grease, soap scum, hair, and other debris. If your pipes are already partially clogged before a storm, heavy rain can push them over the edge, leading to backups.
How to Prevent Drain Backups During Heavy Rains
The best way to avoid a messy and costly drain backup is through prevention. Here are some key steps you can take to protect your home from rain-related drainage issues:
1. Schedule Regular Drain Cleaning
One of the best ways to prevent rain-related backups is by keeping your drains clear. An experienced plumber can inspect and clean your pipes, removing debris, roots, and other blockages before they become a serious problem.
2. Clear Your Gutters and Downspouts
The gutter plays a crucial role in keeping rainwater away from your home. If they get clogged with leaves and debris, water can spill over and pool near your foundation, seeping into your basement and overloading nearby drains. Cleaning your gutters at least twice a year—especially before the rainy season—can save you from costly water damage.
3. Maintain Your Yard’s Drainage System
Find out where all the drains are in your property, and make sure that your yard is properly graded so water flows away from your home instead of toward it. French drains, rain gardens, and properly placed sump pumps can help manage excess rainwater effectively.
4. Check for Tree Root Intrusion
If you suspect tree roots are invading your pipes, call a drain cleaning company to conduct a camera inspection. Early detection and removal of roots can prevent significant damage and costly repairs.
5. Install a Backwater Valve
The Government of Canada’s Climate Change Adaptation Platform indicates that backwater valves are an effective tool for preventing residential flooding. A backwater valve is a simple yet effective device that prevents sewer water from flowing back into your home.
It automatically closes if water starts moving in the wrong direction, stopping backups before they happen.
6. Install a Sump Pump
A sump pump is a great defense against basement flooding. It automatically pumps water out of your basement and away from your home when water levels rise. Be sure to test it regularly and consider installing a backup battery in case of power outages during storms.
7. Avoid Flushing Problematic Items
Avoid flushing wet wipes, grease, and paper towels, as they can slowly clog your pipes over time. When heavy rain hits, these obstructions can worsen, leading to sewer backups. Stick to flushing only toilet paper and human waste to keep your pipes running smoothly.
8. Seal Cracks in Your Foundation
Water can find its way into the smallest cracks in your basement walls and floors. Sealing these cracks with waterproof materials can help keep your home dry even during the heaviest downpours.
