Huge fan of Red Rock Plumbing! They responded to my request immediately and educated me with several different options. I decided to replace my (2) old water heaters (that lasted only seven years!) with one single large tankless water heater. It works incredibly well and the installation is a work of art, thanks to the skilled and expert installation by Nate the head installer. I could not be happier with this new system! Their price was fair, they were extremely easy to work with, not to mention extremely honest and fair! Highly recommend!!
