A Recent Tankless Flush in Timberwood Park
What the homeowner asked for: a flush on their tankless water heater.
What our technician found: sediment buildup inside the unit.
What we did: we flushed the unit and cleaned out the buildup.
Result: the buildup was cleared, and the technician noted the unit was performing well after the flush. The service was completed in October 2026.
How This Tankless Flush Was Done
On this unit, the water supply was closed off and hoses were connected to the service valves. A pump circulated a descaling solution through the heat exchanger and back into a bucket to dissolve mineral scale and loosen sediment. The unit was then rinsed with fresh water and returned to service.
Flushing and maintenance steps vary by manufacturer, model, and equipment type. Our technicians follow the manufacturer’s recommendations and service requirements for the specific unit being serviced.
With San Antonio’s hard water, scale is the main reason tankless units need this maintenance. See How Often Should You Flush Your Water Heater? and Is a Water Softener Worth It in San Antonio?
Exterior and Recessed Tankless Units
Some tankless water heaters are mounted outside or set into a recess box in an exterior wall, as on this job. On this unit, the flush was done through the service valves at the unit.
If a tankless unit has problems a flush will not fix, such as error codes from failed parts, gas supply, or venting, see tankless water heater service.
