Tankless Descaling and Flushing in Daly City
Hard water leaves calcium and magnesium scale inside the heat exchanger, limiting flow and causing overheating. Many units warn of this with scale codes, such as the LC code on Rinnai models.

Frequently Asked Questions About Tankless Water Heater Repair in Daly City
The cost of tankless water heater repair in Daly City varies widely depending on the issue, ranging from $150 for minor fixes like sensor replacement to $600 or more for complex repairs involving heat exchanger descaling or major component replacements. We provide a detailed estimate after identifying the specific problem.
Regular professional maintenance, including descaling and checking all connections, is the best defense. Installing a whole-home water softener can also greatly reduce mineral buildup in areas with very hard water.
Error codes can be triggered by a variety of issues, such as low water flow, gas supply problems, ignition failures, exhaust blockages or faulty temperature sensors. Each code points to a specific system malfunction.
Many common tankless water heater repairs can be completed within 1 to 3 hours, especially if parts are readily available. More complex issues, like extensive descaling or ordering special parts, might take longer and may require a follow-up visit.
Yes, FBL Plumbing stands behind its work. All our tankless water heater repairs come with a satisfaction guarantee and a warranty on both parts and labor. We will provide full warranty details with your repair estimate.
Minor repairs usually 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 Daly City building department may be necessary. We handle all required permitting for you.
Most repairs and descaling are done in one to three hours. If a part must be ordered, we typically return within a few business days.
Fluctuating temperatures can come from low flow rates, a dirty inlet filter, a failing flow sensor or scale on the heat exchanger. Crossed hot and cold lines at a fixture can cause it too.
