We have a Fluidmaster Fill Valve and the chamber that rises up the body of the fill valve is sticking. After flushing, it does not go down and the tank is not filling with water. How can I fix this.
Fluidmaster is low quility but popular ballcock. For the price of a new one,it's advisable to replace the complete valve. You might spend 30 minutes cleaning and lubercating the old one and have it sticking a week latter. There is no replacement part spicifly for the problem.
