"Two years ago Riley Plumbing and Heating replaced the corroded galvanized water pipe from the street meter to my house, so I was very surprised to have another water leak in the back yard last month. Riley Plumbing came out again, and found that the new leak was due to another corroded galvanized pipe that was supplying water to the back yard irrigation system. They replaced this pipe, tying the water supply to the irrigation system to the water line they installed two years ago. Mike Rojas, Luis Ortiz and Aiden did the work in a professional manner, and left the back yard in good shape for re-seeding this fall. (Hopefully no more corroded pipes in my yard!)"

"Bighorn Plumbing was able to come out the same day to replace our water heater in Carson City. We wanted a tankless. The job was completed that same day and now we have endless hot water. Worth every penny."
