Prevent Backflow From a Bad Storm

Heavy storms can spell trouble for homeowners, especially when it comes to your plumbing. One of the most serious threats is backflow — when contaminated water flows in reverse and enters your clean water supply.

Backflow can happen quickly during a bad storm, putting your family’s health and your property at risk. Knowing how to prevent backflow is essential for every homeowner.

What is backflow and why is it dangerous?

Backflow occurs when water flows backward through your plumbing system, bringing dirty or contaminated water into your home’s clean water lines. This can happen when heavy rain overwhelms city sewers or your own drainage system, creating pressure that forces water in the wrong direction. Backflow can introduce bacteria, chemicals and debris into your drinking water, creating a real health hazard.

Plumbing measures to prevent backflow

Install a backwater valve

A backwater valve is a device installed on your main sewer line that allows water to flow out of your home but prevents it from flowing back in. When the city sewer becomes overloaded during a storm, the valve closes automatically, stopping contaminated water from entering your basement or lower levels. A professional plumber can assess your system and install the right type of valve for your home.

Use backflow preventers on outdoor faucets and irrigation

Outdoor faucets, hose bibs and irrigation systems are common sources of backflow. Backflow preventers, also called vacuum breakers, stop contaminated water from being siphoned back into your home’s plumbing. These simple devices are a must for any outdoor connection.

Sump pump maintenance

A working sump pump helps keep your basement dry during heavy rain. Make sure your pump is in good condition, the discharge line is clear and the check valve is functioning. The check valve is a type of backflow preventer that keeps water from flowing back into the pit after the pump shuts off.

Proper grading and drainage

Ensure your yard is graded away from your home’s foundation so water flows toward storm drains and not into your basement. Downspouts should direct water at least six feet from the foundation. Good drainage makes it less likely that stormwater will overwhelm your plumbing.

Regular plumbing inspections

An annual plumbing inspection can identify weak points in your system, such as aging pipes, faulty connections or missing backflow devices. A professional plumber can recommend upgrades or repairs to keep your system storm-ready.

Avoid using plumbing during a storm

When a storm hits and sewers may be overloaded, avoid running dishwashers, washing machines or taking long showers. Reducing water use during heavy rain helps prevent backups.
