2 months agoMike, Ethan, Jose, and Bradley were a fantastic group of guys to work with. They made getting rid of a leaking water heater a breeze even though they had little to no room to work in. They also installed a brand new tankless water heater system. They were able to get the job done in a single day! 100% will be calling ZyNex for any future plumbing needs.
