How to Prevent Sewer Backups and Basement Flooding in Cleveland
Heavy rain and old sewer lines put Cleveland basements at risk. Practical steps — maintenance, backwater valves and inspections — to prevent sewer backups.
Keep your sewer lateral clean, know its condition with a camera inspection, consider a backwater valve, keep downspouts out of the sewer, test the sump pump and limit water use during heavy storms. These steps cut the risk of storm backups.
Spring storms and summer downpours bring the same calls every year: water coming up through the basement floor drain. Here's why it happens in Cleveland-area homes and what you can do about it.
Why sewers back up into basements
Your own line is restricted
Roots, grease, scale or a belly in your sewer lateral slow the flow. When a lot of water hits at once, it has nowhere to go but up — through the lowest drain.
Heavy rain overloads the system
Parts of Cleveland and older inner-ring suburbs have combined or aging sewers. During heavy rain, the public sewer can fill up and push water back toward homes.
Rainwater is getting into your sewer
Downspouts, foundation drains or a broken pipe connected to the sanitary sewer add rainwater to your line exactly when the system is already full.
How to protect your basement
1. Keep your sewer line clean
If you have mature trees or an older home, schedule a drain cleaning or hydro jetting every 1–2 years. A clean line carries water away faster.
2. Know your line's condition
A camera inspection shows roots, cracks, bellies and separated joints. Our $199 sewer camera inspection includes a full report and video, so you know exactly what you're dealing with.
3. Consider a backwater valve
A backwater valve lets water flow out of your home but closes when sewage tries to flow back in. It's one of the most effective protections for homes with a history of storm backups. Check with us and your city about requirements.
4. Redirect downspouts
Downspouts should discharge away from the foundation, not into the sewer, where your city allows.
5. Check your sump pump (if you have one)
Test it before spring by pouring water in the pit. Make sure the discharge runs away from the house.
6. Go easy during big storms
During heavy rain, avoid running the washing machine, dishwasher and long showers. Less water from your house means less chance of a backup.
7. Raise what matters
Keep valuables off the basement floor, on shelves or in plastic bins.
Already had a backup?
That's a sign your line needs attention. Start with a camera inspection, then fix the cause — not just the clog. If it's happening now, here's what to do when your basement floods.
Protect a finished basement
If you're finishing a basement, or already have one, the stakes are higher. Before you put up drywall or carpet:
- Have the main line camera-inspected and cleaned
- Fix any broken or root-filled sections first
- Ask about a backwater valve and a proper cleanout
- Make sure the floor drain is accessible, not buried under flooring
It's much easier to do this before the finishes go in than after the first backup.

Frequently asked questions
What is a backwater valve?
A backwater valve lets wastewater leave your home but closes automatically if sewage tries to flow back in, protecting the basement during sewer surcharges.
Why does my basement flood only when it rains hard?
Heavy rain can overload combined or aging sewers, and rainwater entering your own line through downspouts or cracks adds to it. A restricted lateral makes it worse.
Does homeowners insurance cover sewer backups?
Often only with a specific sewer backup rider. Check your policy before storm season.
