Tank Sediment provides general educational information about water-heater sediment, scale, water hardness and maintenance considerations. The site does not provide plumbing, engineering, electrical, gas, inspection or other professional services.
Water heaters differ by fuel, design, age and manufacturer. General information on this site cannot determine whether a particular heater should be flushed, descaled, repaired or replaced. Follow the manufacturer's instructions and use qualified professional help where appropriate.
Gas, electricity, hot water, pressure, damaged valves and corroded equipment can create serious hazards. Do not use a general article as a procedure when safe isolation, draining, disassembly or restart is uncertain. Stop and seek qualified help if there is a gas smell, active leak, damaged wiring, severe corrosion or other unsafe condition.
Calculators, examples and symptom lists are educational only. They do not measure sediment, diagnose equipment condition, guarantee savings or predict remaining service life.
