Toilet Overflowed onto the Carpet or Floor: What to Do Right Now

Stop the water first

A toilet overflows when the bowl can’t drain, usually because of a clog. The water spilling out comes from the tank refilling the bowl. So the goal is to keep the tank from sending any more water down.

1. 1

   Push the flapper down

   Lift the lid off the tank and set it down somewhere safe. At the bottom, you’ll see a rubber flapper over a hole. Push it down to seal the hole. Len The Plumber notes that the water in the tank is clean, so it’s fine to reach in.

2. 2

   Lift the float

   The float rises with the water in the tank. Lift it up and hold it there. That shuts off the fill valve so the tank stops refilling.

3. 3

   Close the shutoff valve

   Find the small valve near the floor or on the wall behind the toilet and turn it clockwise until it stops. Benjamin Franklin Plumbing says the shutoff valve is the best place to turn off the water. If the valve is stuck, don’t force it. You could break it. Close your home’s main water valve instead.

Once the water stops, hold off on plunging. Deal with the spill first, then come back to the clog.

Clean water, gray water, or black water?

This is the question that decides almost everything else: what you can keep, what you should wear, and whether you need a pro.

This follows the categories restoration crews use. Massachusetts’ public health guidance lists a toilet overflow with urine but no fecal matter as gray water. It lists sewage and toilet backflow with fecal matter as black water, which is highly contaminated.

Can the carpet be saved?

Sometimes, yes. It depends on what was in the water and how long the carpet stays wet.

• The EPA explains that a wet vacuum alone won’t dry carpet. The carpet and pad need to be pulled up and dried, ideally within 48 hours. The floor underneath needs to dry, too.
• The CDC advises throwing away things you can’t clean or dry quickly, including carpeting, carpet padding, and rugs.
• Virginia’s Department of Health says carpets and rugs contaminated with sewage should be discarded.

What about bathroom floors? Vinyl and tile don’t soak up water, but water can slip under the edges, under the toilet, and behind baseboards. If the floor feels soft or spongy, or the vinyl starts to lift, the subfloor may be wet underneath.

Check where else the water went

The spill you can see is often only part of it. Before you call it done, check:

• The ceiling below. If the bathroom is upstairs, look for stains, drips, or a bulging ceiling on the floor below.
• Under the vanity. Water can run under cabinets and stay there.
• Baseboards and the bottom of nearby walls. Swelling, peeling paint, or a wet line can mean water wicked up into the drywall.
• The next room. Carpet can soak up water a few feet past the doorway, even where it looks dry on top.

Cleaning up safely

If the water was clean and only a small area got wet, you can often handle the cleanup yourself. If waste was in the water, protect yourself first.

• Gear up. The CDC says to wear rubber boots, rubber gloves, and goggles if sewage is involved.
• Keep kids and pets out. Virginia’s Department of Health says to keep all children and pets away from sewage.
• Soak up, then clean, then disinfect. Remove the water, wash hard surfaces with soap and water, and then disinfect them. Leave the disinfectant on as long as the label says.
• Never mix bleach with ammonia or other cleaners. The fumes can be dangerous.
• Wash your hands with soap and clean water when you’re done. Wash your work clothes separately, in hot water and detergent.

When should you hand it off? Virginia’s health department suggests hiring a professional if your insurance will pay for it, if sewage has stayed in a finished living space for more than 24 hours, or if the job is too big to handle yourself. A soaked bedroom or hallway carpet is often more than a DIY job.

When it’s more than a simple clog

One overflowing toilet is usually a clog in that toilet. But watch for these signs that the problem is deeper in the line:

• Water backs up into the tub or shower when you flush.
• Several drains are slow or gurgling at the same time.
• Water comes up through a basement floor drain.
• Plunging the toilet doesn’t help, or it overflows again right away.

If you see any of these, stop using water in the whole house and call a plumber. For a sewer backup in a home on Boise city sewer, the City of Boise asks you to call Public Works right away at 208-608-7200. Outside Boise, call your own city or sewer district.

Who to call

To be clear about which call fits: a plumber fixes the toilet and the pipes. A restoration crew deals with your house: removing water, drying the floor and walls, and safely removing materials that can’t be saved.

Does insurance cover a toilet overflow?

Often, yes, but it depends on the cause. Your own policy has the final word.

• Farmers says a toilet overflow can be covered if a clogged pipe inside your house or a fixture failure caused it, unless poor maintenance was to blame. It says an overflow caused by a sewer backup typically isn’t covered without water backup coverage.
• The Minnesota Department of Commerce explains that a typical homeowners policy won’t cover sewer backups, and that you need a separate add-on for that.

• Take photos and video before cleanup.
• List anything you throw away, and photograph it first.
• Keep receipts for cleaning supplies, fans, and plumber visits.
• Read any contract carefully before you sign it.

Since soiled carpet often can’t wait for an adjuster to visit, ask your insurer how they want you to document it before it goes out. For the full process, see our guide to water damage insurance claims in Idaho.

Choosing help without pressure

It’s okay to ask questions before you hire anyone, even when the carpet smells. Ask what they plan to remove, what they’ll try to save, and how they’ll show you it’s dry. Get it in writing. Our guide on how to choose a water damage company in Boise has a short checklist you can use on the phone.
