I hired Hydro Plumbing and Heating on Thursday evening to replace both of my 50 gallon gas heaters with a new tankless water heater. My floors were soaking wet from the units (both) that failed! Hydro told me they would be at my home @ 8:30 am Friday; they showed up at 8:00 am ready to go to work. Less than four hours later my warm showers were running! In addition, I paid 15% less than I next low bidder. Thanks for the GREAT experience!
