Customers' right side kitchen sink had tail piece that was rotted through completely. Customer agreed to replace basket strainer and tail piece. Removed old tailpiece and strainer and then replaced both pieces secured and tested no leaks. While at the residence I talked to the customer about their pressure being high at a hundred and ten psi, and the fact that their water heater is very old. I recommended replacing both item. They are not going to move forward with that at this moment in time. Thank you for choosing and trusting te with your plumbing needs
