Place your left hand on the top of the valve cap and while placing your left hand thumb on the side of the arm coming out of the top. Turn the cap and lever counter clockwise 1/8th of a turn to unlock. You should be able to lift off the cap and lever from the valve body. Once the cap assembly has been removed inspect for debris on the seal (rubber disc with pin coming through) and also the valve portion still in the tank. Hold a cup upside down over the exposed opening of the valve and turn on the water supply full force for 10-15 seconds, allowing the pressure to free any debris inside the valve inlet.
Reassemble the top of the valve by placing the cap arm next to the refill tube. To lock, press the cap down while turning it and the arm clockwise. If you find no debris in the valve, then the seal may need to be replaced. If your valve is more than 2 years old, replace the seal (located in the cap assembly).

The top hand is gripping the cap while the thumb is pressing on the raised lever arm.Ten Common Toilet Problems and the Solutions You could have a first generation 1.6 gallon flush toilet that is destined to failure. Look inside the tank for a manufacture date stamped in the clay. If it was made during the time period from January 1, 1994 to mid-1997, this could be the problem. No matter what you do, it will not flush right. If the toilet was made before 1994, hard water deposits in the syphon jet hole or the angled bowl rim swirl holes may be the source of your frustration.
You can try to clean them out with wood sticks and oversized toothpicks, but a muriatic acid wash will really do the job. Mix one part acid to 10 parts water. Using a funnel, carefully pour one half of this solution down the overflow tube in the toilet tank. You should immediately hear fizzing and such. BE CAREFUL of the fumes! Run the bath fan, open a window. DO NOT splash this solution on you, in your eyes, on your clothes, on the carpet, etc. It will not hurt the toilet at all. If you have a septic system, do not do this! The only way you can clean your toilet is to disassemble it and do this process outdoors. Let the acid work for about 30 minutes. Pour the remainder of the solution down the overflow tube. After an additional 30 minutes, flush the toilet. You should see an improvement. The flapper valve may be waterlogged and dropping too fast. Observe the flapper valve during a flush. It should stay up until about 80 percent or more of the water has drained from the tank.
If it drops sooner, install a new flapper. This is really a phantom filler, as the toilet tank fills with water as if it was just flushed. It simply means that the tank is leaking water.

Heeler Puppies For Sale In WisconsinAfter 5 or 10 minutes, look at the bowl water to see if it is colored. If it is, the flapper is not sealing completely. Time for a new one! You flush the toilet and all is well. After a period of time, a significant amount of water has left the bowl. Two things may be wrong. Water could be slowly siphoned from the bowl by a partial clog of toilet paper up in the colon of the bowl.
You can demonstrate this phenomenon by filling a small soup bowl with water and putting it in the center of a cooking jelly pan. Drape a strip of paper towel from the bottom of the bowl, over the bowl edge and into the jelly pan. Watch what gravity and capillary attraction does in several hours. The bowl will be nearly empty. To see if your toilet has a rag, toilet paper, or something else causing the drainage, empty the bowl of water and then use a flashlight and a mirror to look up inside the colon of the toilet. In rare cases, the bowl may actually have a crack in the interior colon or piping of the bowl. This problem can only be solved by installing a new bowl. The water level in the tank may be set too high. Lower the level and look for improvement. You must have an old technology ball cock valve with a ball float on the end of a rod. As the ball floats higher it begins to slowly close the water fill valve. This can cause vibrations and all sorts of noise. Toilet tank fill valves that stay wide open until the tank is filled have been around for over 20 years.
They are wonderful and they are inexpensive. I use the Fluidmaster valve. Get the best one, not the economy model. This problem may be a partially closed shut off valve under the tank. A previous owner or a plumber may have restricted the flow of water into the tank for some reason. After the tank has filled, you hear dripping. Then several minutes later, the tank partially fills with water and the dripping starts again. Then the tank fills and so on and so forth. This problem can be a syphon problem caused by someone who installed a new tank fill valve. There is a small flexible tube that runs from the bottom of the valve to the top of the toilet overflow tube. As the tank fills, water is also sent through this tube. It is used to refill the toilet bowl since it lost its water during the flush. If this tube drops down inside the overflow tube, it can, in some instances, syphon water from the tank. New toilet fill valves often have a clip that attaches to the top of the overflow tube and points the water flow down into the tube without actually having the tube enter the tube.
