You might want to see if the clog works itself out in time. If you have another toilet you can use, let the clogged one set overnight. The water pressure that builds up in the bowl might actually cause the toilet to unclog itself. After a day's wait, flush the toilet again.
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.
The water level will go down after 15 minutes, so pour more hot water into the bowl to restart the lubrication process. After another 15 minutes of waiting, you can flush the toilet and the clog will be gone!
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.
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.
You may just be using it incorrectly. Do this: Next time you have a clog, use your plunger like this: Ensure the flange lip is unfolded. Get a good seal on the toilet drain (that is, make sure you're covering the entire drain or you won't have enough pressure to loosen the clog.)
Check water level in toilet bowl
Listen for a gurgling sound from the drain (a good sign) and check the water level in the toilet bowl. If nearly all the water drained from the bowl, then you've probably cleared the clog.
Then pull up sharply to disturb the clog and loosen it. Continue vigorously pushing and pulling until the water begins to drain. It may take 15 to 20 cycles before the toilet unclogs. Be patient.
The longer you leave a clog, the more opportunities there are for the clog to get worse. The most water-soluble parts of the clog will dissolve, and the rest will fill in the gaps, making the clog worse. There is also the possibility that human error could come into play.
Attempting to force a clog through a toilet with a plunger can often make the problem worse. Instead, create a seal and slowly push down on the plunger before pulling it back sharply. The suction can help pull the clog back up toward the bowl, breaking the blockage and allowing gravity to take over.
Home Repairs
If declogging requires you to go the extra mile, i.e., take steps that do not need a plunger—don't DIY it! You must contact a plumber immediately before the clogged toilet causes any health hazard and leads to overflowing water.
When it comes to simpler clogs, expect to pay no more than $150, while more extensive blockages that require dismantling the toilet's plumbing could cost between $150 and $500. A DIY drain snake costs between $5 and $50, so it may be affordable for homeowners to take the first attempt at unclogging themselves.
You may have a first-generation, low flow design. The low flow design was created to help homeowners save on water, but the earliest models ended up lacking the necessary pressure to properly clear the internal trap and drain. In other words, this means that it can continuously become clogged if you aren't careful.
Using too much toilet paper
This is probably the most common reason toilets get clogged — and often the easiest to deal with. If we're honest, most of us are probably guilty of this one. If you're one of the many people who use a lot of toilet paper when you use the bathroom, here are a few tips!
Toilets can develop drain clogs for any one of several basic reasons, usually involving partial or complete obstruction in one of the various parts of the drain system: the toilet trap, the branch drain line, the vent pipe, or the main sewer line.
Structural Damage – if your clog is not immediately addressed, the pipes can burst and cause other structural damage to your home. In addition, your toilet might back up and flood your bathroom floor.
Bleach or chemical drain cleaner.
For those tough clogs that seem like they are impossible to solve, you could try to use harsher chemicals, like bleach or a store-bought toilet drain cleaner. The chemicals contained in these can be harmful to yourself and your pipes, so only use them as a last resort.
You can use Drano® Clog Removers to unclog a kitchen sink, bathroom sink, shower or clogged bathtub, but DO NOT use them in toilets. For clogged or slow-running drains, apply the product and let it work 15 minutes, then flush with hot water. For tough problems, allow 30 minutes before flushing.
Pour a half cup of dish detergent (degreasing dish detergent like Dawn works best) into the clogged toilet. Follow this with three to four cups of boiling water. The boiling water and degreasers will break up the clog, sending it right through.
