Sewage backups are a disaster. But we don’t have to tell you that. If you’re experiencing one, there’s only one question on your mind. What should I do? It’s easy to be overwhelmed by the situation. Your basement or living area may be flooding. Stay calm, know that it can be fixed, and read on. We’ll teach you what to do when your basement floods with sewage.
Stop the sewage from coming into your home
So there’s human waste flowing up from your tub, toilet, or drain. How do you even begin to fix this problem? The first step is to control the source of the damage. You can’t clean up the sewage if it’s still hemorrhaging into your home. But how? What if you aren’t a plumber? What if you don’t have the right tools?
First, try to assess what is causing this backup. You don’t necessarily have to be a plumber to make a few deductions about the source of the issue. When the sewage backup started, were you:
- Using your dishwasher
- Using your washing machine
- Using a shower
- Draining a tub
Backups indicate a problem
Most backups occur when water is being used in the house and isn’t able to drain out of your building drain fast enough. Think of your plumbing like a funnel. If you were to pour water into a funnel too quickly, it would overwhelm the opening and backup – or overflow. If the opening of the funnel was clogged with debris, the water you poured in would back up even faster. In your sewer’s case, if a clogged pipe is impeding the flow of water or you are draining too much water too quickly, you are at risk of a sewage backup.
The pipes in your home’s building drain system are sized and installed in a way that backups shouldn’t occur under normal conditions. As long as your home’s plumbing was installed to a plumbing code standard, it follows a system of “DFUs.” Drainage Fixture Unit Values – or DFUs – have been determined by the Uniform Plumbing Code to determine how much water volume your sewer and drains can handle. This means that every pipe is sized to handle the discharge of each plumbing fixture connected to that section of pipe. Even if you were to use every toilet, shower, sink, etc at the same time, your plumbing is meant to handle that water without backing up. That is, unless something is wrong.
Immediately stop water usage
If you notice sewage flooding up from a drain or toilet, stop the immediate use of water. Simply stopping water usage for a brief time will stop the backup in this instance. Keep the dishwasher and washing machine from draining. Stop the long showers. Space out these uses of water and give your pipes some time to slowly drain off until a plumber can come and diagnose the underlying problem.
Salvage important possessions
What if the problem doesn’t stop when you cut off the water drainage? In our case a few weeks ago, the sewage backup was the result of a problem in the county sewer main. Even though we weren’t using any water in our home and no matter what appliances we shut down, the entire neighborhood’s wastewater continued to flood into our basement. If this is the case for you, immediately call the municipality and/or a plumber. While waiting for help to arrive, try to salvage as many of your possessions before they are touched by sewage. Try to save irreplaceable items first, such as photo albums or family heirlooms that would otherwise be ruined.
Who should I call when my sewer backs up?
As mentioned above, if you can’t stop the sewage backup, you need to call the municipality and/or your trusted plumber. In Baltimore City and Baltimore County, your home must have an exterior cleanout at your property’s edge for the municipality to help you. If the city/county can’t assist you because you don’t have an exterior cleanout, call a licensed plumber. Unfortunately, there is not much you can do without the tools and plugs you need immediately on hand when a blockage is off your property.
If sewer backups are a frequently recurring issue in your home, you should call a plumber for a diagnosis and plan of action. Even if the problem is off of your property, having a plumber involved can often speed up the resolution of your problem. Often, a plumber can provide you with proof that the sewer problem is not on your property.
How to clean up a sewage backup
- Cut off electricity to the damaged area
- Stop water use
- Put on personal protective gear
- Take photos or video documenting the damaged area for insurance purposes
- Dispose of any damaged property
- Clean up standing wastewater and sewage with a shop vac
- Mop with bleach solution
- Spray mold prevention solution on any wood or organic surfaces
- Run a dehumidifier
Cut off electrical power to the area
Most sewage backups occur in basements or on the first floor of homes. These spaces have outlets, appliances, lights, wires, etc that pose an electrical hazard during flooding. Before entering the damaged area, the electricity should be shut off. If the power can be turned off to the affected area, do not endanger yourself by entering the area.
Stop water use
As mentioned at the outset of this article, continued water use during a backup can worsen the problem. Stop running your dishwasher, washing machine, sinks, and showers until the problem is resolved.
Put on personal protective gear
There are many harmful things in sewage, from bacteria to dangerous objects that may have been sent down the drain. Personal protective equipment should be worn when entering the area where the backup occurred. Safety glasses, rubber gloves, rubber boots, and a face mask can help keep you safe from the viruses, bacteria, and overall gross contents of the sewage.
Take photos or video documenting the damaged area
Before cleaning up, it would be wise to take some photos or a video of the area damaged by sewage. This documentation is handy for showing your insurance company the extent of the sewage backup. It is also a great way to show any of your possessions that may have been damaged during the flooding. Proof of damage and destruction may help toward the replacement or reimbursement of your damaged property.
Dispose of any damaged property
Inevitably, some of your belongings will be ruined from the sewage backup. Throw away anything that can’t be easily disinfected. This includes carpet, boxes, clothing, books, etc. Truth be told, you may want to get rid of more than you think you should. Be generous with what you think was damaged. You don’t want mold to occur because you didn’t remediate enough. Thoroughly sanitize cleansable possessions.
Clean up and dispose of wastewater
Time for the fun part. Cleaning up the sewage may seem like a daunting task. A few helpful tools to have on hand are a wet/dry vac, a push broom, a mop, a 5-gallon bucket, and bleach. Vacuum up as much of the waste as you can with the wet/dry vac. Check with your municipality about where they recommend for you to dispose of this wastewater. The push broom is helpful for moving all of the waste to a central part of the room for easier vacuuming.
Disinfect the area after disposing of large solids and liquids. Mix the bleach with water in a 5-gallon bucket according to the manufacturer’s instructions. Use the bleach solution to mop or douse the floor and walls (if unfinished). You may find it beneficial to vacuum again. This is a long process but killing viruses and bacteria is crucial.
Spraying a fungicide and antiviral is a good idea. Any organic surfaces like wood or fabric are liable to grow mold after flooding. Be generous with how much you spray.
Run a dehumidifier
Run a dehumidifier after you clean up the area. This works best when placed centrally in the room and used in conjunction with box fans to provide airflow. This combination helps ensure that your floors and walls dry out, in addition to any other surfaces and objects in the area that have become damp. Thorough drying can help prevent mold from growing. Ventilating the area is a good way to get rid of the sewage odor as well.
Depending on the severity of the sewage backup in your home, you may want to submit an insurance claim. Taking photos as mentioned in the steps above is a helpful tip if this is the route you choose. If the damage is extensive, your insurance company will recommend a restoration and remediation service. If you decide that the DIY cleanup method isn’t for you, and your insurance doesn’t cover the sewage backup, you may still want to hire a professional. Look for a well-reviewed and accredited water and mold restoration company. They will handle all cleanup and remediation … for a price.
Sewage backup prevention
After enduring a sewage backup, it isn’t surprising that you never want a repeat occurrence. So how can you prevent sewer clogs and plumbing backups? You can keep your drains healthy and your wastewater flowing OUT of your home with drain cleaning.
Some clogs are a one-time issue. It could be something as simple as a toy accidentally flushed down the toilet. Other clogs are chronic. Root intrusion, sediment buildup, or defects in the pipe can catch sewage and toilet paper, creating a blockage. An expert plumber can do a great drain clean. You can research a C.A.
