Las Vegas Plumbing Fixtures
A toilet is a unique plumbing fixture in your bathroom because the trap is built into the toilet and not into the drain pipe (if you look under your sink, you will see the trap in the drain pipe). The water in the bowl seals out the sewer gasses from entering the room, as well as provides a medium for the waste.
I have never used chemicals to clear a toilet.
They take too long to work and typically are made to work on hair and grease.
You have a couple of different choices. You can use a plunger, a closet auger or hydro-static pressure. If you are in a pinch, grab a bucket and some water and cross your fingers.
Hydro-static pressure is a fancy way of saying that you are going to force water down the bowl. This works fairly well if the water level in the bowl is low. Simply take a bucket (a five-gallon bucket is good), and fill it about half full. Hold it waist high and pour it into the opening at the base of the toilet bowl. The pressure of the water entering the trap from a height may solve the problem.
Beware of course that the potential for an errant splash is possible. You want to aim right for the trap-way (the hole at the bottom of the toilet) and put is much water in that hole in the least amount of time as possible. I would start slow and once you have your aim down, then go Niagra Falls on it. If this doesn’t work, the bowl will have more water in it than when you started, and you can move to the plunger.
