Well, I don't really understand plumbing, because I'm not an
emergency plumber , but maybe you need to change some gaskets there to make the water stops dripping. Look on the internet about what could be the problem, I think with the help of the internet you can find the answer. I just had a leaky faucet once, and it was only with the help of the internet that I figured out what the problem was and was able to fix it. I doubt that you have some complicated problem that you can't solve on your own.
