  • Professional Descaling Flush: We’ll clear out mineral buildup from your tankless unit to keep it running efficiently and extend its lifespan.
  • System Inspection: We check connections, venting, and the overall health of your unit to catch any potential issues early.

Overtime, calcification and sediment can build up in your tankless. By regularly flushing the unit, you can fight back against the challenges of time. Regular inspections and cleanings help you be proactive against unexpected breakdowns and inefficient performance.

As certified Rinnai and Navien technicians, we’re qualified to keep your tankless performing perfectly year round. Tankless water heaters are sophisticated technology, and shouldn’t be trusted to just anyone. Make sure your tankless is in the hands of a qualified, experienced plumber.

Many manufacturers require an annual flush to keep your warranty valid, making this one service you don’t want to skip.

Looking to reduce your tankless water heater cost in the long run?

To decrease your tankless water heater flush cost, consider installing a whole home water filtration system, which will protect your plumbing system from sediment and mineral build up. Plumbing systems with a whole home water filter can have their tankless units flushed less often.


The tankless water heater flush cost, with this limited time deal, easily pays for itself by lengthening the life of your tankless and preventing costly repairs. If a tankless is not properly maintained, sometimes a full replacement is the only option when a component breaks. This annual flush helps protect your investment, reduce unexpected issues, and keep your hot water flowing strong.
