Installation was good except blew out pilot light to hot water heater when turned off liquid propane. Had to come back and reset but did so promptly with no charge,. Very courteous and clean which is unusual for most plumbers I have used. Could have a standard price for installation. I was charged by the hour and it took two to install. I could have arranged installation from place I purchased at 85 an installatiojn. It cost me 75 x 2 hrs=150 plus tax. A little expensive for an install. But does good work and might consider him for another job.
