Ernesto did a superb job in replacing the main water line and associated plumbing fixtures. His work is high-quality and he strives for utmost customer satisfaction and fair pricing for his work. Prior to starting the job, he researched codes to ensure that the new line would be placed at the appropriate depth. He also acquired all of the necessary copper piping and parts using suppliers with the best pricing and using only high-quality materials. Ernesto is very good at troubleshooting and finding solutions to unforeseen obstacles (such as cutting away concrete where it was not expected). Ernesto started and completed the job within the timeline he proposed. I couldn't be happier with the outcome of this large, complex project. I highly recommend Ernesto and E-Flow Plumbing for any plumbing task, large or small!
