Common Toilet Problems

A household toilet can be wreaked with a slew of problems. Let’s take a look into them and their respective causes. But before we do that let’s know how a toilet works. When you flush a toilet, there is a chain that lifts up the flapper valve. The water then goes through the flush valve that opens into the toilet bowl. This water forces waste water in the toilet bowl through the trap and into the main drain. Now that the tank is empty, the flapper valve closes. The fill valve that has the ballcock opens up to refill the tank. When the tank is full, the float ball shuts off the fill valve/ballcock.
Water on the toilet floor

This can be caused due to variety of reasons. It could be due to a leaking toilet tank. You can put some coloring in the tank water. If you see color in the toilet bowl after sometime, it could be a case of leakage. Check the tank bolts, the fill valve/ballcock mounting nut, and supply tube coupling nut. If these are all intact, you may need to replace the washer.

Dripping water from the side of the tank could also be caused by condensation. This would happen during humid weather. This happen because the water that flows into the tank has a lower temperature than that of the room. To stop this you have to ventilate your bathroom well. You can also resolve this by placing a toilet liner kit. This is a foam panel placed inside the tank.
A leak can happen due to cracked toilet tank. You have to replace it that case. A cracked toilet base can also cause leakage of water. The wax ring that seals the toilet base to the floor may have gone lax. You can call a plumber to replace the wax ring.

Not flushing

This can be caused due to many reasons. You should check the flush handle, if it is working properly. It may have gone too loose or tight. The tank cover should be removed to clean the mounting nut (located on the inside behind the handle). The handle may now work smoothly. Sometimes lime can build up around the mounting nut, in that case clean it with a brush dipped in vinegar.
Also check the lift arm which may be broken. The connection between the lift arm and lift chain may be broken resulting in the flapper valve not lifting properly to allow the water to flush out. The flapper 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. Level of water too high or low can also cause this problem.

Clog in the toilet

To determine this you can pour 5 gallons of water from a bucket in to the toilet. If it dumps into the trap without any splashing, the drain is unclogged. If water backs up into the bowl and drains slowly, it is a clog. Call a plumber to unclog the drain.
Slow-Filling Toilet

This happens if the valve that opens up to allow the water to get inside the tank is not working properly. You can dissemble the fill valve and clean it. Sometimes replacing the fill valve diaphragm seal helps the situation. Replacing the fill valve/ballcock is also a good idea. These are available at reasonable price and can be installed on your own by following the manufacturer’s instruction.
