<human>:  How do I fix a running toilet?
<bot>: To fix a running toilet, you will need to start by shutting off the water supply to the toilet. Then, remove the lid from the toilet tank to locate the water float and ballcock assembly. Check to see if the chain that runs from the flush handle to the flush valve is broken or too long. If so, adjust the chain or replace it. Lastly, replace the fill valve and flush your toilet.
