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.
In an effort to dislodge whatever is clogging the toilet, many homeowners get overzealous and thrust too hard downward into the toilet with their plunger. 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.
Check water level in toilet bowl
After plunging for thirty seconds, quickly break the seal and remove the plunger. 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.
Lower the plunger into the toilet bowl at an angle, and fit the rubber cup over the toilet's drain hole. Grip the plunger handle with both hands. With a forceful motion, move the cup up and down without breaking the cup's seal around the hole. Repeat this action for about 10 to 20 seconds and then remove the plunger.
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. Flush to see if the clog has cleared. If not, repeat.
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.
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.
Start slow and add force as needed. Several gentle pumps will usually work better than a couple of hard pushes. If your blockage is going to come out, it should happen in less than 10 minutes.
Plunge Out the Water
After shutting off the water supply valve, place the flange of a toilet plunger (also called a closet plunger) firmly into the drain hole in the bottom of the toilet bowl. Plunge with an up-and-down motion to get most of the water out of the bowl. This should force out any clog into the drain.
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.
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).
Baking Soda And Hot Water
Pour about half of a cup of baking soda down the drain and then follow up with a pot of boiling water. Let it sit for an hour or two before you try flushing again. It might take several attempts, but this method has been known to work really well in unclogging slow draining 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.
We recommend you add a cup of baking soda to your blocked toilet and wait for some minutes. Next, pour two cups of vinegar slowly into the toilet. Vinegar and baking soda will typically react to form bubbles, so ensure you pour carefully and slowly to prevent the toilet water from overflowing or splashing.
Confirm that there is standing water in the toilet bowl. Sometimes clogs cause a toilet to slowly drain its bowl. You cannot plunge a toilet that is empty, so if there is no standing water, use a cup to fill the toilet with water from your sink.
Once you force out the air, plunge vigorously in and out, maintaining the seal. You'll be forcing water in both directions in the drain, which will effectively loosen most clogs. Stick with it, plunging 15 to 20 times if necessary.
Hot water will break down the grease better and when aided by a cleaning agent, grease is a goner. While cold-water jetting can bust through a blockage, you will not truly clean a pipe and rid it of the FOG buildup unless you clean it with hot water.
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.
A manual drain snake, also known as a plumber's snake or a drain auger, is a small boring tool that rotates slowly as it's physically pushed through a stubborn clog. The terminal end of the device is a corkscrew-shaped hook that is fed into a clogged drain or toilet.
A drain auger is a better choice, but the wire hanger will work in a pinch.
Blocked Toilet Vent
The toilet vent allows fresh air to enter your home's plumbing system, which increases the pressure of flushes. If a toilet vent becomes blocked, the toilet loses flushing pressure. With poor pressure the toilet keeps clogging more frequently, and clogs become a consistent problem.
