Water Heater Flush — Same-Day Tank Cleaning & Maintenance
142 Customer Reviews
Hard water in the Lowcountry builds up sediment inside your water-heater tank, making it work harder and wear out faster.
Elemental Appliance Repair offers same-day and next-day water-heater flush service across Charleston, Summerville, Nexton, and nearby areas.
A professional flush helps your unit heat faster, last longer, and use less energy while keeping your water clean and safe.
We educate, not upsell.
Our technician shows the real buildup inside your tank and explains when a flush, element change, or full replacement truly makes sense.
If your heater still has years left, we’ll help you keep it running longer not pressure you to buy a new one.

Full post-service testing
After the flush, we refill, purge air, relight (for gas units), test for leaks, and confirm stable temperature so you’re confident everything’s safe before we leave.

About Our Water Heater Flush Service
We connect your tank to a professional flush system that safely removes old water, sediment, and mineral buildup.
The process includes:
- Shutting off power or gas for safety.
- Draining the tank through a high-flow hose.
- Rinsing interior sediment until water runs clear.
- Inspecting the anode rod, valves, and fittings.
- Refilling, purging air, testing temperature, and restoring full operation.
Most flushes take 45–60 minutes, and you’ll notice quieter operation and faster hot-water recovery right away.

FAQ
At least once a year in Charleston’s hard-water areas. If you hear popping noises or see cloudy water, it’s overdue.
If sediment was restricting heat transfer, yes. If the element or thermostat is failing, we’ll test and show you next steps.
