If you’ve noticed that flushing your toilet is causing water to come out of the drain in the bathtub, then you’re going to need to know how to unclog a toilet that’s backing up into the bathtub.
The plumbing for your tub, sink, and toilet usually connects to one main drain line. Since the tub’s plumbing is set lower than the sink and toilet, if there’s a clog in the toilet, it can sometimes cause the water to bubble up out of the bathtub drain.
If you’ve tried to use a plunger in the toilet to get rid of the clog and find that the backup is still affecting the bathtub, then you might have a clog located in the main drain line.
To remove the blockage, you should have a few supplies:
- Flat sewer rod or auger
- Sponge or cloths
- Adjustable wrench
Sewer rods and augers are used to either push down or fish out whatever debris may be trapped in the pipes.
You’ll need to locate your clean-out plug which is usually found in the garage, basement, or near the house’s foundation. Use your adjustable wrench to take the plug off. You can catch any water that may leak out of the plug when you pull out the clog with your bucket.
If you’re using a sewer rod, push the rod into the clean-up until you hit the clog. Push the rod back and forth until you feel it’s breaking the clog apart.
If you need to use an auger to locate the blockage, insert and push until you feel it come up against resistance. That will usually indicate that you’ve reached the source of the clog. Rotate the handle clockwise to hook the auger’s tip into the blockage. Once you feel it has connected, pull the cable to help dissolve the clog.
Whether you use the rod or auger, make sure you work them down the drain line towards and away from the house to eliminate any other possible issues.
Following these directions should take you step-by-step on how to unclog a toilet that’s backing up into the bathtub. If you want to reduce your chances of dealing with clogs, then you might want to consider a low-flush toilet option that uses less water and decreases your odds of your toilet backing up.
