Dave Harvey came out to quote the job. Professional, prompt, friendly. Installer was also on time and did a great job, making sure to explain job etc.
We've used Konkle for previous jobs ie Backflow prevention valve in 2014, gas line hookup to whole home generator in 2003 etc and have always had great service and follow-up. They take the time to explain things and size things appropriately to make sure things work as intended.
