Dwyer was great. My old water heater broke and flooded my utility room. Called Dwyer at 7:00 am and they had someone to my house by 8:50. The plumber was professional, courteous, knew exactly what they were doing. Not only did he replace the water heater, but he made sure to improve the plumbing connections to the heater (including a new and better water valve), checked every water and gas connection for leaks and adjusted the pressure valve from the main water line. They were done by 12:00.
