Pride Plumbing came out and provided a cost estimate to replace a non-working 50-gallon electric lowboy water heater with either a new 50-gallon electric lowboy model or a new Navien 240A tankless model with a NAVICIRC recirculation pump. This would include removing and disposing of the old water heater after disconnecting its electrical connections, vent lines, and gas and inlet and outlet water lines; and installing the new water heater along with making its appropriate electrical, gas (if applicable), and water connections; ensuring that the unit is properly vented, lighting its pilot (if applicable); and setting it to its appropriate operating temperature.
