Tankless Descaling and Flushing in San Leandro
Hard water leaves calcium and magnesium scale inside the heat exchanger, restricting flow and causing overheating. Many units warn of this with scale codes, such as the LC code on Rinnai models. We connect a circulation pump to the service valves and run a descaling solution through the exchanger. Annual descaling is a smart move for most homes on hard water.

Tankless Water Heater Descaling Service in San Leandro
Hard water can lead to mineral buildup, or scaling, in your tankless water heater's heat exchanger, reducing efficiency and eventually causing breakdowns. Homes on hard water see scale on fixtures and water heaters, while very soft water can be slightly corrosive to older copper pipe. Our descaling service in San Leandro involves flushing the unit with a dedicated cleaning solution to dissolve these mineral deposits. This preventative maintenance and repair step is crucial for extending the lifespan of your tankless heater and keeping it at peak performance.
Tankless Repair vs Replacement Cost in San Leandro, CA
Descaling service usually costs $175 to $350, and sensor or igniter repairs run $250 to $600. Heat exchanger replacement can cost $800 to $1,500 or more unless covered by warranty. A new tankless unit installed usually ranges from $3,000 to $5,500. We compare these costs against the age and condition of your unit.

Timely repair of these components prevents hazardous gas problems and restores your unit's ability to heat water on demand.

If your tankless unit will not fire, the cause may be a dirty flame rod, a bad igniter, low gas pressure or a blocked intake. We test each component and measure gas pressure at the inlet.

Frequently Asked Questions About Tankless Water Heater Repair in San Leandro
The cost of tankless water heater repair in San Leandro, CA can range from $150 to $800 or more, depending on the issue. Simple fixes like sensor replacements might be at the lower end, while major component replacements like a heat exchanger could be higher. We provide a detailed estimate after diagnosis.
We stand behind our tankless water heater repairs with a comprehensive warranty on both parts and labor. The specific warranty period will be discussed with you before any work begins, providing you peace of mind.
While some basic troubleshooting, like checking the power supply or gas valve, can be done, most tankless water heater repairs require special tools and knowledge. Attempting DIY repairs on gas or electrical components can be dangerous and void your warranty. It is always best to call a licensed plumber.
Typical signs include inconsistent hot water, a sudden loss of hot water, strange noises like banging or popping, a rotten egg smell or error codes displayed on the unit. Any of these symptoms warrant a professional inspection.
Regular maintenance, particularly annual descaling, is crucial for tankless water heaters in homes with hard water. It prevents mineral buildup, maintains efficiency, extends the lifespan of the unit and helps avoid costly repairs by catching small issues early.
With regular descaling, tankless heaters often last 15 to 20 years. Without maintenance in hard water, problems can start within a few years.
Minor repairs typically do not require a permit. If the repair involves major changes to the gas or water lines, or if the unit itself is being replaced, a permit from the San Leandro building department may be necessary. We handle all required permitting for you.
Some homeowners do with a kit if service valves are installed. Diagnosing error codes and replacing sensors, igniters or gas components should be left to a pro.
