Why it matters to you
Local water chemistry and sediment load make flushing genuinely valuable in the Lowcountry rather than a nice-to-have, especially for homes on wells or with noticeable hardness.
Practical guidance
Plan on flushing a tank water heater about once a year, and treat a rumbling or popping tank as a sign it is overdue. An old drain valve that has never been opened can stick or leak, so a technician's flush is the safer first time.
