Common causes of a slow-flushing toilet include low water levels, a partially clogged drain, mineral build-up on the jet holes, a defective flapper, and a blocked drain vent.
Boiling water can help to dissolve the clog and free up the pipes. To use this method, bring a pot of water to a boil and pour it into the toilet. Let it sit for a few minutes, and then flush the toilet. If the clog is still there, repeat this process until it's gone.
Many people think that a forceful push into the plunger is what frees up the clog, but this can often worsen the problem. In fact, pushing the plunger in with enough force can even break the seal of the toilet gasket (the seal between the toilet and the floor where the plumbing exits).
Ideally, no more than five or 10 minutes. One plumber told us that if plunging goes on any longer, it's time to try a toilet snake or call an expert.
Caustic soda is a nasty chemical that can burn, but it's very effective for unclogging toilets. To use this chemical, you need to get some rubber gloves and eye protection. You can pick the chemical from the local hardware or grocery stores. Pour a ¾ gallon of cold water into a bucket, and add 3 cups of caustic soda.
Is it okay to leave a clogged toilet overnight? In most cases, you can leave a clogged toilet overnight. However, calling an emergency plumber near you might be warranted if water starts leaking from the pipes. A simple clog likely won't cause this, but an inexperienced homeowner messing with the plumbing could.
Waiting to deal with your toilet's clog for a few hours can be harmless. But, waiting longer than that can cause some issues that you probably want to avoid, including: Overflows: Some toilets have small leaks that run all of the time.
Plunging down too hard
A hard thrust downward can break the wax seal between the toilet and the floor, causing a leak. And a really hard thrust could even crack the bowl.
If you find that your toilet bowl still drains properly — but slowly — then the issue may lie in the jet holes that surround the rim of the toilet bowl. The build-up of sediments and minerals along the side of these holes can gradually reduce the water pressure released with each flush.
Place the plunger over the hole in the toilet. Maintain a seal and plunge up and down rapidly, keeping the plunger under the water level and lifting it only an inch or so on every upstroke. Be patient, as it may take multiple plunge cycles, of a dozen plunges per cycle, to loosen the clog.
Baking Soda & Vinegar
The combination of baking soda and vinegar is an excellent way to dissolve clogs. For toilet clogs especially, add one cup of baking soda to the bowl and let it sit for a few minutes. After that, slowly pour in two cups of vinegar. Let the mixture sit again for an hour, then flush down the toilet.

Make your own drain cleaner by pouring one cup of baking soda and two cups of vinegar into the toilet and adding a half gallon of hot water. Dish soap can also help loosen some obstructions. When using either method, allow the solution to sit overnight and then flush the toilet to see if the obstruction has cleared.
Using a plunger is one of the most effective methods used for unblocking a toilet as it can unclog a wide variety of waste pipes.
The easiest and first thing to try when attempting to unclog toilets without a plunger is hot water. The addition of hot water might be enough to loosen the clog and dislodge the blockage. Fill a bucket with about a gallon of hot water from the sink or bathtub. Then pour the hot water into the toilet bowl.
