Noritz Tankless Water Heater Replacement After Error Code 121 – Installation of Noritz EZTR50 in San Diego

This project occurred in San Diego, CA, where our team at Happy Plumbing Inc. replaced an aging Noritz NRC663-FSV-NG tankless water heater that was no longer functioning reliably. The new system installed was a Noritz EZTR50, chosen for its efficiency and longevity. The installation included full compliance with current building codes and new exhaust ventilation. The project includes a 6-year parts and labor warranty, contingent upon annual descaling performed by Happy Plumbing, as well as a 25-year manufacturer warranty. The first annual descaling is provided at no cost to the customer.
