I am currently experiencing a vibration when I engage the water fill valve to the toilet. Subsequently, I can't use my toilet without pouring a bucket of water to flush it. Do I need a new water fill valve. It sounds like air pressure, if so, how do I get rid of it?

thanks

Vibration is caused by a object in the ballcock vibrating against something as water rushes by . You may shut the water off to the tank and take the three screws out of the top of the float ball assembly and pulling assembly up and out. Check to make nsure that the washer is tight in its place and turn the water for a minute to flush out the supply and ballcock body. reassemble and test. If t6here's still a problem then simply change out the ballcock. good luck, Tom
