I am a professional plumber, and I recently completed a job at a customer's home. The customer had requested that I install a new toilet for them. I arrived at the customer's home and began the installation process. I removed the old toilet and disposed of it properly. I then installed the new toilet, making sure that it was level and securely attached to the floor. I connected the water supply lines and the drain pipe, and tested the toilet to make sure that it was working properly. Finally, I cleaned up the work area and made sure that the customer was satisfied with the job.
