Descale the Unit Annually
Descaling or flushing the entire tankless unit is crucial. It is often considered one of the most important maintenance tasks. This removes mineral buildup (mostly calcium and magnesium) from the heat exchanger.
How to Flush a Tankless Water Heater:
- Turn off the power and water supply to the unit.
- Connect a submersible pump to the cold water service valve using a hose.
- Attach another hose to the hot water service valve and run it into a bucket.
- Fill the bucket with white vinegar or a descaling solution (approx. 2–3 gallons).
- Circulate the solution through the system for 45–60 minutes.
- Flush the unit with clean water to rinse out the vinegar or chemicals.
- Disconnect the pump and hoses, and restore the power and water supply.
Do these steps look very technical and going to be hard? You need not worry. Hiring a professional is a smart option. A pro can do the job safely and efficiently without risk of damage.

A small inline water filter remains in the tankless unit. The purpose of these filters is to trap debris and sediment. Over time, this filter can clog and restrict water flow, reducing system performance.
Steps to Clean the Filter:
- Turn off the water supply to the heater.
- Locate and remove the filter (usually at the cold water inlet).
- Rinse it under running water or soak it in vinegar if needed.
- Reinstall and turn the water supply back on.

To Check the TPR Valve:
- Turn off the power and water.
- Carefully lift the valve’s test lever to see if water discharges from the system.
- If water doesn’t flow or the valve leaks afterward, it may need replacement.
If there is a faulty TVR valve, you should never ignore it. If you are unsure, call a lisenceed plumber for quick fixes.
Look for Error Codes
