Help: My Toilet Is Overflowing!

Why Is Your Toilet Overflowing?

An overflowing toilet is the definition of a plumbing inconvenience, and if not taken care of correctly it can lead to huge disaster for your plumbing system. There are three main reasons a toilet will begin to over flow.

Those reasons are a blocked vent pipe, an improperly placed too high filler float, or a clogged/blocked drain. If your toilet starts to overflow, you need to act fast to minimize the dirty water that ends up on your bathroom floor. Follow these step-by-step instructions below.

What To Do If Your Toilet Is Overflowing

  1. Open your toilet tank and push down on the flapper to close it. The flapper is a circular rubber valve attached to a chain at the bottom of the tank. By closing it, you’ll cut off the flow of water into the toilet bowl.

  2. Find your toilet’s water shut-off valve (outside the tank). It should be located near the base of your toilet by the wall. Turn the valve clockwise until the water shuts off. This will keep any additional water from entering your toilet.

  3. Look back inside the tank and locate the float. It might look like a round or oblong rubber ball on a lever (if it’s a float ball) or a cylindrical, cuplike component (if it’s a float cup) with the longer, skinnier, cylindrical fill valve running through it.

  4. Arrange the float so that it will stay in its current position. You may need to tie it or secure it with something. This will prevent any more water from filling the toilet tank.

How to Clean Up

If your toilet has overflowed, then you’ll probably have some clean-up to do afterward. Don’t delay this step, as toilet water from the bowl is highly unsanitary (unlike water from the tank, which you have not yet “used”).

  1. Put on gloves, a mask, and eye protection to avoid infection from sewage bacteria.

  2. Line a bucket with plastic and shovel any solid waste into it. You can transfer that waste to your garbage can outside afterward.

  3. Soak up the water with towels. You’ll need to wash them with bleach and hot water afterward to sanitize them. If a lot of water has spread, you may want to use a wet/dry vacuum cleaner.

  4. If carpeted bathmats have gotten dirty, it’s best just to throw them out and replace them.

  5. If sewage water has soaked into your walls, furnishings, or carpeting, you’ll need to call a water damage restoration company. They can help you with the necessary restoration and sanitization to keep your home hygienic and safe.

Dealing With the Toilet

The most common culprit behind an overflowing toilet is a plumbing clog. While wearing gloves, try to clear the clog with a plunger. A flange plunger will work best. If you can’t remove the clog with a plunger, contact a plumber. They might need to cable to the clog loose or look for an obstruction in one of your vent pipes.

I have used green planet a few times. One time was an emergency clog, They were prompt and reasonably priced. Their most recent visit was planned work that was needed on my older home. They were honest and fair, did quality work, answered all my questions, explained my options and gave me sound advice. Green planet is who I call whenever I have a plumbing need. They have always done right by me

Justin rocks. He is incredibly knowledgeable and professional. Keeps it clean and courteous. As a contractor, I have had him and the green planet team rough in and trim out multiple jobs and even work on my own home. Couldn’t recommend a better plumber.

I am SO relieved to have found Green Planet, a plumber I can trust. For years, I had a colleague in my business networking group who did amazing work without bait and switch and ridiculous markup, but he retired. Green Planet came recommended by my next door neighbor. They first did routine maintenance on my rental unit, but this week I called them with a bit of urgency. My water shut off valve snapped off, thankfully when I was not in an emergency, like a burst water pipe. I decided to have them also fix a toilet that on occasion would run for hours and an exterior spigot that was shooting water the wrong direction. Technician arrived within 45 minutes, took a look at everything, and provided a written estimate. He discussed what could go wrong once we removed drywall and fixtures, but made every effort to work diligently to avoid these scenarios. One of the main issues would be the presence of old, corroded, pipes versus modern pex. He had the spigot and toilet fixed quickly and then focused on the main project. Steady lines on the drywall removal help make it easy for me to replace that. Once done, even with a quick parts run to the warehouse, he was wrapped in about 90 minutes with everything looking great. We discussed my aging hot water heater, and options to install an upgraded toilet, so I can make plans to budget those projects down the road. Such a relief to have a company I can trust after some bad experiences with the big brands you see on TV (I see how those types of companies can afford big splashy campaigns).

We had a really great experience with Eddie from Green Planet. We had a shower faucet that was leaking, and also the handle had completely separated from the faucet. Green Planet doesn’t change for an estimate which was really appreciated, and also their estimate to replace the cartridge in the faucet was less than half what other companies had charged us for the same service. We were weighing whether to replace the entire faucet, and he gave us helpful thoughts on that as well. We chose to go with a cartridge replacement because to replace the faucet they would have had to open up a wall. We didn’t have a dry waller in mind. The repair was fast and works great. Thanks so much Green Planet!

It was a pleasure to have Justin and Henry replace our hot water tank and snake out our kitchen sink drain. They were very pleasant and easy to talk to and made sure all questions and concerns were answered. Very rapid response, I called for an estimate and they were here the next day. I approved the work and they were able to start the work the following day. They arrived early and got right to work. They protected all exposed surfaces before starting. When complete they made certain that we understood how to operate the controls on the tank and explained all they did. All at a reasonable cost. We definitely will call Green Planet Plumbing again for any future plumbing needs.
