Noritz Tankless Water Heater Tune-Ups in Hays, KS

Inlet Filter and Air Intake Cleaning in Hays
Every tankless unit has an inlet water screen that catches grit and scale flakes. Those screens can clog with sand and debris, especially after municipal line work. We pull and clean the screen and inspect the air intake filter, which can load up with dust and dryer lint. Clean filters keep the flow sensor reading accurately and the burner breathing properly.

Residential Tankless Water Heater Flushing in Hays
Water across much of Kansas runs quite hard, leaving mineral scale in water heaters, faucets, showerheads, and dishwashers. Hard water can lead to heavy mineral buildup in tankless water heaters. Our residential flushing service in Hays involves circulating a descaling solution through your unit's heat exchanger to remove calcium and magnesium deposits. This process restores efficiency, prevents overheating and extends the life of your appliance, so your family gets continuous hot water without interruption.
Tankless Water Heater Venting System Check in Hays
Proper ventilation is critical for the safe operation of gas-fired tankless water heaters. Our maintenance service in Hays includes a thorough inspection of the venting system for blockages, proper slope and secure connections. We make sure that exhaust gases are safely directed outside and that no carbon monoxide leaks are present, which is vital for the health and safety of your household.

Heat Exchanger Descaling in Hays
The heat exchanger in a tankless heater is a coil of small tubes that water races through while the burner fires. Hard water drops calcium and magnesium on those hot surfaces, narrowing the passages over time. We connect a submersible pump and hoses to the service valves and circulate descaling solution for 45 to 60 minutes. Then we flush with fresh water to rinse the system completely. Restored flow means more stable temperatures and fewer shutdowns.

Frequently Asked Questions About Tankless Water Heater Maintenance in Hays
Most tankless descaling visits cost $175 to $350, depending on brand and access. Adding an isolation valve kit usually runs $150 to $300 more.
Once a year is standard, and homes with very hard water and no softener may need it every six to nine months. Heavy users and commercial units need it more often.
With regular descaling, many tankless heaters last 15 to 20 years. Neglected units in hard water can fail in less than half that time.
The descaling process involves shutting off the unit, isolating the water lines and connecting a circulating pump to flush a specialized acidic solution through the heat exchanger. This solution dissolves mineral deposits like calcium and magnesium, which are common in hard water, improving heat transfer efficiency.
Usually, a permit is not required for routine tankless water heater maintenance, such as flushing and inspections. However, if major repairs or component replacements that alter the original installation are needed, a plumbing permit from Hays may be necessary to ensure compliance with local building codes.
KRV Plumbing services all major brands of tankless water heaters, including Rinnai, Noritz, Navien, Bosch, State, Rheem and more. Our technicians are trained on the specific maintenance requirements and diagnostics for a wide range of models to ensure expert care for your unit.
Most visits take one to two hours, including the descaling cycle. Installing isolation valves on the same trip adds about an hour.
Most tankless water heater manufacturers recommend annual maintenance to support good performance and extend the unit's lifespan. In areas with harder water, more frequent checks, perhaps every 6 to 9 months, might help to prevent excessive scale buildup.
