I was looking to get a double-check valve installed for backflow prevention and ultimately went with PlumbPros Plumbing to get it done. I worked closely with Richard, who was always very quick to respond, and he came out quickly to look at the job for me. He even took time to call Cobb county water in order to find out what was required, a step that nobody else did for me when I was getting quotes. PlumbPros had a very reasonable rate. They did everything to find out where it needed to be installed, and how to test it. They went above and beyond to make sure the job was done correctly. He even gave me a contact list of people I can speak with if I had any further questions. I've replaced our former plumbing company with theirs on our contact list for contractors, and I would use them again.
