Pride Plumbing came out and replaced the thermopile on a gas water heater. We also provided a cost estimate to replace the unit with a new customer-supplied model. 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, water and gas ball shut-off valves, new water and electrical connectors, brass drain valve, atmospheric vent, and thermal expansion tank; ensuring that the unit is properly vented, lighting its pilot, and setting it to its appropriate operating temperature.
