The answer to 'faucet won't flush' is that there could be several common causes, such as a clogged drain, a faulty flapper, or a problem with the water supply. Symptoms may include the faucet not releasing water or water not draining properly.
Some DIY solutions to try include checking for clogs in the drain, cleaning the faucet aerator, and replacing the flapper. However, if the issue persists or you're not comfortable making repairs, it's best to call a professional plumber to diagnose and fix the problem.
