A: There are a few signs that your fill valve may need to be replaced, such as a constantly running toilet or a toilet that takes longer than usual to refill. Additionally, if you notice water leaking from the tank or the valve itself, it may be time for a replacement.

Q: Can I replace a fill valve myself?

A: Yes, replacing a fill valve is a relatively simple DIY task that can be done with basic tools.
