The answer to 'why is my faucet won't flush' is that there could be several common causes, such as a clogged drain, a faulty flushing mechanism, or low water pressure. The most likely issue is a blockage in the drain or plumbing system that is preventing the faucet from properly flushing.
Some key symptoms you may notice include water not draining properly, a slow flushing action, or a complete failure to flush. To troubleshoot, you'll want to check for any visible clogs or debris in the drain, and you may need to disassemble the faucet to inspect the internal components.
