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.
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).
Unfortunately, the pressure from a plunger probably won't break up a shower drain clog. Instead, it will only send the material deeper down the drain pipe completely intact. The clog still exists, but now it's even deeper into your plumbing system, causing your shower to drain slowly or not drain at all.
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.)
Don't use excessive force when plunging a clog. Also, keep in mind that you shouldn't use too much pressure because it can damage the drain line connection, which will lead to further problems eventually.
However, if the clog is especially tough, your plunger may not be enough. So, what else can you do to clear a badly clogged toilet? The first thing you should do is stop flushing. If your toilet doesn't drain, persistent flushing will only fill the bowl with more water, making the problem worse.
Bacteria and Smells
We're spoiled by the fact that we flush and our mess goes away. You might not realize just how strongly a clogged toilet is going to smell after a few hours. Along with the smell from the clog, you may smell bacteria as it grows. The sitting water gives bacteria ample time to set up shop.
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.
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.
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.
Wait about 10-15 minutes before trying to unclog the toilet, as some water might drain on its own. Squeeze a lot of liquid dish soap, about one cup, or pieces of bar soap into the toilet bowl.
So, let's recap the common reasons why a toilet won't unclog — excessive toilet paper use, non-flushable solids, hard water, and clogs in the main sewer line. Thankfully, they can be prevented via methods like double-flushing, covering the toilet bowl, routine inspections and dealing with tree roots.
The auger or plumber's snake is a long, flexible tool that can be pushed into the toilet as far as the blockage.
There is only one Drano® product recommended for use in slow-running toilets: Drano® Max Build-Up Remover. It contains microorganisms that break down organic matter in pipes that can slow water flow. (However, it will not open a completely clogged toilet. For that problem, see How to Unclog a Toilet.)
A drain auger is a better choice, but the wire hanger will work in a pinch.
Plunger. While this tool might appear basic, it remains the best way of unclogging a toilet. We recommend all households to have this tool and preferably one with a flange because they work best to unblock toilets.
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.
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.
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.
Give a few good up and down strokes with the plunger and flush the toilet. If the water clears from the toilet, then you've successfully unclogged it. If the toilet starts overflowing again, just close the flapper to stop water from entering the bowl. Repeat the plunge and flush sequence until your clog is gone.
Maybe. If your toilet is constantly clogging, the problem could be the toilet itself or it could be something else entirely (like a sewer or septic line problem). So before you rush off to purchase a new porcelain throne, make sure the toilet is really the problem...
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 is an effective way to deal with blocked toilet drains as it is a dilute solution of sodium hypochlorite and also contains a high chlorine concentration. Using bleach by itself or mixing it with boiling water are effective ways to unclog a toilet.
