Annual Tankless Water Heater Inspection in Michigan City
An annual inspection of your tankless water heater in Michigan City is a proactive measure against costly repairs. Our complete check includes examining the gas line connections for leaks, testing the pressure relief valve, inspecting the igniter and cleaning the air intake filter. We look for any signs of wear or potential failure, giving you recommendations to keep your system running smoothly all year long, through hot spells and cold snaps alike.
Heat Exchanger Descaling in Michigan City
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 thoroughly. Restored flow means more stable temperatures and fewer shutdowns.

Recirculation and Combi System Service in Michigan City, IN
Many tankless units now include built-in recirculation pumps or buffer tanks to deliver faster hot water. These systems move more water through the exchanger and scale up sooner. We flush the recirculation loop, check pump operation and verify crossover or dedicated return line settings. Correct schedules can reduce wasted energy while still giving you quick hot water.

JKN Plumbing provides preventative maintenance for all major tankless water heater brands, including Navien, Bosch and State, across Michigan City, IN. Our technicians are cross-trained to handle the specific requirements of each manufacturer. We perform descaling, filter cleaning and component checks tailored to your specific model, ensuring long-term reliability and manufacturer warranty requirements, regardless of the brand.

Inlet Filter and Air Intake Cleaning in Michigan City
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 correctly and the burner breathing properly.

Frequently Asked Questions About Tankless Water Heater Maintenance in Michigan City
Most tankless descaling visits cost $175 to $350, depending on brand and access. Adding an isolation valve kit usually runs $150 to $300 more.
Rinnai shows LC codes, Navien may show E003 or E030 and Noritz often shows 90 or 99 when scale or airflow is a problem. These codes usually clear after proper cleaning.
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.
A softener or scale prevention system greatly reduces buildup in the heat exchanger. Some brands even recommend treatment when hardness is high. Groundwater supplies much of Indiana, and it tends to run hard to very hard, leaving scale in water heaters, fixtures, and appliances.
Many tankless water heater manufacturers require proof of regular, professional maintenance to keep your unit's warranty valid. Skipping annual service can cancel the warranty, leaving you responsible for costly repairs that would otherwise be covered. Always check your own warranty terms.
If you have isolation valves, a pump and the right solution, a handy homeowner can do it. A pro visit also checks gas pressure, venting, sensors and condensate, which a DIY flush skips.
No, routine maintenance, such as flushing and inspection, usually does not require a permit in Michigan City. Permits are typically only needed for new installations, major repairs that involve altering gas or water lines, or replacing an entire unit. We will advise if any permit is needed for complex repairs.
A standard tankless water heater maintenance service, including flushing and inspection, typically takes 1 to 2 hours. The exact time can vary depending on the unit's condition, the amount of scale buildup and any unforeseen issues encountered during the service.
