Signs that your toilet fill valve is bad include a toilet that won't stop running, takes too long to fill, makes unusual noises, or doesn't flush properly. You might also notice water running from the valve itself, indicating a leak. If adjusting the float doesn't solve the issue, it's likely time to replace the valve. It's a relatively easy DIY fix that can save water and reduce your utility bills.
