The toilet fill valve is one of two main components inside the toilet tank. If the fill valve is worn, damaged, or not operating properly, it could cause a leak from the toilet tank base or lead to the toilet continually filling. By replacing the fill valve assembly, you can reduce wasted water and lower utility bills.
On average, toilet fill valves last 5 years without any issues, depending on the quality of the valve, hard water content, and how frequently the toilet is flushed. The toilet fill valve is located inside the tank, and is responsible for allowing water to flow into the tank and stopping the flow once the water level reaches a set point.
If the toilet keeps running after flushing or runs intermittently when not in use, it could indicate that the fill valve is leaking or has failed, in which case you will need a toilet fill valve replacement. Learn how to identify if a toilet fill valve is malfunctioning and steps to follow when replacing the part.
