What our service work and the manufacturer documentation say about keeping this model running.
Inspect vessel, heating elements or coil, thermostat, safety valve, drains, insulation and circulation connections. Check for scale, corrosion and leakage and maintain water treatment appropriate to domestic service. Verify temperature control and safety devices using approved procedures. Inspect electrical terminals where heaters are fitted and ensure pressure relief is not isolated. Investigate repeated safety-valve discharge or slow heating. Refer to the manufacturer documentation for the exact figure for pressure, temperature, element and inspection limits.
Keep thermostats, temperature sensors, heating elements where fitted, safety-valve service parts, gaskets, circulation-pump seals and manufacturer-recommended anodes where applicable. Pressure-vessel repairs must follow approved procedures. Confirm all wetted parts are suitable for potable water.
