Another good idea is to check on the tank to bowl bolts and washers and the spud gasket. If the rubber washers or the gasket are breaking down,, now is the time to replace them as well.
Many thanks for the very informative and detailed video tutorial. I also liked the cool video technique with the shots from inside the tank and another angle from the floor as you left the toilet room at the end.
Keep uploading videos please. New homeowners like me need you. I guess I'm a Plumber trainee now. Never heard toilet sounds EVER until I bought this house 😞
Wish I could find this brand of fill valve online. The only website that I could find that sells it doesn't list a price without creating an account with them :(
