How to Unblock a Toilet: DIY Methods That Actually Work

Few things evoke the same sense of panic as a blocked toilet. The water starts to rise, you stand frozen, and every second seems to last an age.

Why toilets get blocked in the first place

Understanding why your toilet has decided to go on strike can be helpful before we dive into solutions. The most common reason is using too much toilet paper, especially if it’s the quilted, thicker variety that doesn’t dissolve as well. Flushing non-toilet items like baby wipes, cotton buds, or feminine hygiene products is another common cause. Sometimes the issue is a build-up further down the waste pipe that over time reduces the diameter inside the pipe. And sometimes, yes, it’s what you suspect it might be. Regardless of the reason, the approach to resolve it is generally the same.

The hot water and dish soap trick

This method is always my first suggestion because it involves no special tools whatsoever. Boil some water in a kettle, let it cool for a minute or so (you don’t want it boiling hot, as it can crack porcelain), squirt some dish soap into the toilet bowl, and then pour the water into the toilet bowl from about waist level (the pressure helps). Then wait 10 minutes and let gravity and dish soap do their thing. If you come back and the water level has dropped, do one flush, and you’re usually done. This really is how to unblock a toilet most of the time without getting your hands dirty.

How to unblock a toilet without a plunger

If the hot water method fails, there are plenty of other options before you start hyperventilating. The baking soda and vinegar method is famous for a reason. Pour a half-cup or so of baking soda down the loo, followed by a cup of white vinegar. It will foam, which is the desired outcome, as this chemical reaction aids in dissolving the blockage. Wait 20 minutes or so, and then try to flush it with some warm water. Knowing how to unblock a toilet without a plunger is especially useful if you rent or don’t keep a plunger around. Another technique is using a straightened wire coat hanger with a cloth wrapped around the end to gently manoeuvre out whatever the blockage is. This is a bit more manual but can be quite effective if the blockage isn’t far from the bowl.

When the plunger is your best friend

Alright, there’s a reason plungers have been invented. If you have one, use it. The key here is having the right one. A flange plunger, which has that extension that folds out from the bottom, is the one designed for toilets and will make a better seal on the bottom than a flat cup plunger. Slowly push down to squeeze out the air, then quickly pull up. Do this 5 or 6 times. You should feel the blockage move. Knowing how to unclog toilet blockages with a plunger is probably the most foolproof method you can use. Once the water begins to drain, flush the toilet a few times to ensure that the blockage is gone. And keep a plunger handy. Every household should have one.

What that gurgling sound means (and when to call a plumber)

If you start hearing strange gurgling noises coming from your toilet, particularly when you flush it or when another drain in the house is used, that’s your plumbing system trying to tell you something. A toilet gurgling is usually a sign that there is a venting issue or partial blockage somewhere in your drainage system. This happens when air becomes trapped in your pipes and can’t escape. Sometimes it can be fixed with a good plunging, but if the gurgling persists, it could be a sign of a bigger issue, such as tree roots in your sewer pipe or a collapsed pipe. This is a good time to call in a licensed plumber. If you’ve tried all of the DIY methods above and your flush toilet is still blocked, or if you find that the same blockage keeps happening, there may be an issue with the cistern toilet mechanism or even a faulty fill toilet valve that is affecting your flush power. A plumber can run a camera down the line to locate the problem and spare you a lot of frustration.

FAQs

How long should I wait before calling a plumber for a blocked toilet?

Allow the DIY methods at least 30 minutes to an hour before calling for help. If you’ve tried using hot water and dish soap, the baking soda trick, and a plunger and your toilet is still blocked, it’s time to call in the professionals. But whatever you do, don’t continue to flush a blocked toilet. You’ll only end up with a bigger mess on your hands.

Can I use chemical drain cleaners to unblock a toilet?

While you can, I would advise against it. Most chemical drain cleaners aren’t designed for toilets and can actually damage the porcelain as well as the rubber gaskets and pipe joints over time. The methods outlined above, hot water, baking soda and a plunger, are safer and just as effective.

What if my toilet keeps blocking every few weeks?

If your toilet seems to be blocking every few weeks, there’s probably a bigger issue at play. It could be a partial obstruction further down the waste pipe, an issue with the pipe gradient, or tree roots. A plumber with a drain camera can help you determine the underlying cause. In the meantime, knowing how to unclog toilet blockages as they happen is handy, but don’t ignore the pattern.
