The answer is found in the fill valve model used in the toilet tank. Fluidmaster, for example, allows for rapid repair by simply replacing the seal inside the device. Other brands, on the other hand, may not be as repair-friendly. The only option if the toilet flush valve cannot be repaired is to replace the complete machine.

How Do I Clean a Toilet Flush Valve?

Debris and silt can clog fill valves. Cleaning them is, thankfully, simple. After removing the fill valve’s cap, look for any debris that may have become lodged in and around the fill valve’s body. Turn on the water supply by placing an inverted cup over the open fill valve. This will force the water to circulate through the fill valve’s body, allowing the debris or sediments to be released. To clean the fill valve, repeat this procedure at least twice.
