Several things cause the toilet to "keep running." Either the flap in the bottom of the tank isn't sealing shut. When you push the handle, a chain connects an arm on the handle to the flap on the bottom of the tank. The flap opens letting the water in the tank run through the bowl flushing the floaties down the drain. After the tank is empty, the flap should seal off the bottom of the tank and let it refill. So, if the tank isn't refilling, make sure the chain isn't too long and getting tangled on the flap and not letting it close.
Also, the float valve can go bad. When the tank refills there is a float mechanism that is supposed to shut the water off when it gets to a certain level. If the float is out of adjustment or doesn't work any longer, there is an overflow tube where the water in the tank will overflow into the tube and down to the bowl. If the tank is full and won't stop running, check for adjustment on the float mechanism (there are many differant styles). Your local hardware store will sell new float assemblies (and any other toilet parts) at a pretty reasonable price. Toilets are pretty much standard and many differant parts can bolt right in so the local hardware may recommend a differant valve than what you have. The directions that come with the valves are usually pretty good.
Even though you might have to pay an extra buck for parts, it would probably be a good idea to visit the local hardware store instead of a large homecenter. I've found that the local hardware owner is usually very knowledgeable and willing to teach you how to use his products. It can be more difficult to get the wealth of knowledge from the large homecenter store.
The water level in a toilet bowl drops when there is a clog in the drain pipe, a faulty flapper valve, or a problem with the water supply.
The water level in a toilet bowl decreases when there is a blockage in the plumbing system, a faulty flapper valve, or a leak in the toilet tank. This causes water to slowly drain out of the bowl, resulting in a lower water level.
The toilet bowl water level drops when there is a clog in the drain pipe, a faulty flapper valve, or a problem with the fill valve.
Water drains from the toilet bowl after flushing because the force of the flush pushes the water down the drain pipe, creating a suction effect that pulls the water out of the bowl.
Water runs in the toilet bowl to maintain proper water levels and to flush waste down the drain when the toilet is flushed.
The toilet bowl is empty of water because the water has been flushed down the drain, carrying waste with it.
Water may be overflowing from the toilet bowl due to a clog in the drain pipe, a malfunctioning float valve, or a problem with the toilet's flushing mechanism.
The toilet bowl is empty because the water has been flushed down the drain, leaving the bowl dry until it is refilled with water for the next use.
The water may not be staying in the toilet bowl due to a clog in the drain, a faulty flapper valve, or a problem with the water level in the tank.
The purpose of the toilet overflow tube is to prevent water from overflowing in the toilet bowl by providing a pathway for excess water to flow into the toilet's drain pipe. When the water level in the tank rises too high, the overflow tube directs the excess water into the drain pipe, preventing it from spilling over the edge of the bowl.
To fully drain a toilet, turn off the water supply valve located behind or near the toilet. Then, flush the toilet to remove as much water as possible. Use a plunger to push any remaining water out of the bowl and into the drain. Finally, use a wet/dry vacuum to suction out any remaining water in the bowl and tank.
To drain a toilet bowl effectively, start by turning off the water supply valve located behind the toilet. Next, flush the toilet to remove most of the water. Use a plunger to push any remaining water down the drain. You can also use a wet/dry vacuum to suction out the water. Finally, use a sponge or towel to soak up any remaining water in the bowl.
