You shortened the chain too much. Make it longer a link at a time till it works.
The toilet keeps running because there may be a problem with the flapper valve, fill valve, or flush handle that is not sealing properly, causing water to continuously flow into the toilet bowl.
Linkage going to flapper is sticking or needs adjusted. Nut holding flush handle to tank may need tightened or replaced. Pressure assisted toilet needs more force on handle to flush.
Common issues that can arise with a toilet tank include leaks, running water, and a malfunctioning flush mechanism. Leaks can be fixed by replacing the flapper or tightening connections. Running water may be due to a faulty fill valve, which can be replaced. A malfunctioning flush mechanism can be fixed by adjusting the chain or replacing the handle.
The toilet flapper may not stay up due to a worn-out or misaligned flapper, a problem with the chain or handle, or issues with the water pressure or tank level.
The flush mech or flapper is faulty or your handle needs to be adjusted.
To replace the flapper on a Kohler one-piece toilet, first turn off the water supply to the toilet. Remove the tank lid and flush the toilet to empty the tank. Disconnect the flapper chain from the flush handle and remove the old flapper. Install the new flapper by attaching it to the mounting ears on the flush valve. Reconnect the chain to the flush handle and turn the water supply back on. Test the flush to ensure the new flapper is working properly.
Clogged toilet, mainline stoppage, not enough water in the tank or bowl, too much slack in flapper chain, bad flapper, broken handle...
To be honest, my whole family have had to hold down the handle to get it to flush in one of our toilet for two years until today that I searched this page and do my trouble shooting. I replaced the Flapper two years ago, and did not realize that the first step that you need to do is to cut the collar off from the new Flapper if your toilet has mounting arm. The Flapper is designed to fit two different kind of toilets, the one with mounting arm and the one that doesn't have(and thus need a collar). If the collar is not cut off. it generates push down force every time you press the handle to flush the toilet. That is the reason that you need to hold down the handler. Inside the tank, there is a flush valve. Depending on the age of the toilet, it typically either is a "flapper" or "tank ball' style. Each type have a little bouyancy...when you press tank handle, the suction is broken, and the flapper or ball floats open. As the tank empties and the water level gets lower in the tank, the flapper or ball re-settles on its seat. Your flapper or ball is not floating open. Look inside tank, press handle. Observe flapper or ball. If the flapper or ball does not float open, you may need to simply shorten the chain...just a little. Typically, you can readjust the chain linkage where it connects to the handle. Also, you can pull the chain from inside the tank...without using the handle to see how it is supposed to work and determine how much slack is needed in the chain. Good Luck The "floating open" problem in the previous answer may be from a deteriorating flapper. The upside down cup that holds the air may be torn, and allow the air to escape too fast, dropping the flapper prematurely. I had the same problem and thanks to these previous answers, I solved my problem. It is very hard to describe parts without pictures, but here goes. There is the small hose that emits water into a "column" which goes to the "rubber flapper". I first checked my flapper to see if it had eroded and it seemed fine, actually almost new. While I was checking that, I noticed that the flapper had a rubber round part which instead of being over the "column", was behind the column. It made sense to me that this round rubber part should go over the column, so I pulled the flapper off at the sides where it was connected (by these two small tabs) and pulled the rubber ring up and over the column. I pushed the ring all the way down to the bottom of the column and over the two plastic tabs at the bottom of the column. I then felt around and made sure the flapper was not leaking (kind of like checking to make sure a rubber stopper in a sink is not leaking) and it was good. The chain was adjusted so there was not a lot of slack. I had a toilet that was constantly running in the powder room. It is an Eljer installed when the house was built in 1992. The flapper valve was quite deteriorated and the flush handle/lever was worn and sticking. I replaced the other 2 toilets in the house with much higher quality Toto toilets a few years back. Money is tight at the moment so I decided to just fix this one. I bought a new "Korky" flapper valve and a replacement flush handle at a local hardware retailer and replaced them. After this I noticed that the water level in the bowl was much lower after refilling and that I had to hold the lever down to get it to complete a flush. After reading the above answers and several others from other websites I took the lid back off the tank and this is what I found: The new flapper valve was manufactured with a hole in it that immediately let the air out once the flapper valve is vertical, causing it to drop down and reseal the tank too soon. I shut off the water and removed the flapper valve, dried it off, and placed a smal piece of electrical tape over the hole to see if the flapper valve would then perform properly and it did. Also I noticed that when I had done the original work I failed to replace the bowl refill tube back into it's original location in the overflow tube and that was what was causing the lower water level in the bowl after flushing. There is nothing complicated or requiring long explanations about this - Simply remove flapper, get a universal flapper and fit it - done !
The purpose of the chain in the toilet tank is to connect the flush handle to the flapper valve. When the flush handle is pressed, it pulls the chain, which lifts the flapper valve, allowing water to flow from the tank into the bowl for flushing. The chain plays a crucial role in activating the flushing mechanism by controlling the movement of the flapper valve.
The purpose of the toilet handle arm is to lift the flapper or flush valve inside the toilet tank, allowing water to flow from the tank into the toilet bowl to flush waste down the drain. When the toilet handle is pressed, it pulls on the handle arm, which in turn lifts the flapper or flush valve, releasing water into the bowl for flushing.
The toilet flapper may not go down due to a blockage in the flapper valve, a problem with the chain or handle, or issues with the water level in the tank. It is important to check these components and make necessary adjustments or repairs to ensure proper functioning of the toilet.
Put a new flapper in the tank. The flapper is what the handle is attached to. They get hard over time and don't seal completely so the tank drains and then refills.
