Welcome to Just Answer, my name is ***** ***** I will do my best to help you with your issue. First I’ll need some more info so I have a more complete picture of you situation.
Are you talking about the fill valve for the toilet tank?
Ok, if this is a 2 piece toilet (separate tank bolted to the bowl) you should just replace the fill valve. A Fluidmaster is your best bet. Fluidmasters are widely available, inexpensive (<$15) and come with good instructions.
You're description indicates the valve is failing and needs to be replaced. It's a pretty easy replacement for a moderately skilled DIY'er. A plumber would charge $100 to $150 depending on where you live. I can post a link to instructions if you like so you can see if you want to tackle this yourself.
I'm sorry for the misunderstanding but I did answer your question in detail. I diagnosed the problem and gave you an inexpensive solution which which is far less money than what you'd spend on a plumber. Even if you don't do this yourself you know what the problem is so the plumber won't be able to sell you something you don't need. Contact customer service if you have a question about the charges. http://ww2.justanswer.com/contact-us
I have nothing to do with billing or your account. Please contact customer service at the link above to discuss this with them.
