Common Tankless Unit Repairs We Can Handle

We’re experienced at handling various issues, including:

  • Lack of Hot Water: Water temperature fluctuations could be caused by a clogged heat exchanger, low flow rate, or insufficient gas pressure. 
  • Persistent Leaks: Leaks that keep coming back may be the result of loose connections (from poor installation), faulty pressure relief valves, or a damaged heat exchanger. 
  • Strange Noises: If your pump fails or air gets trapped in the system, your water heater could make strange noises. 
  • System Error Codes That Are Unfamiliar: Depending on the tankless unit model, there could be several reasons you’re seeing error codes.

Miguel and Mateo did a terrific job installing a new hot water heater. They were very professional and cleaned the garage floor and walls in and around the affected areas. I was and remain impressed. I also appreciate the efforts of Chris Danko who planned and supervised the project. Cheers!

Why DIY Tankless Water Heater Repairs Aren’t Recommended

While homeowners can perform several troubleshooting steps, attempting complex repairs or tasks involving gas lines or electrical wiring isn’t recommended, especially if you’re untrained.

We highly discourage DIY repairs because:

  • You may accidentally create more significant issues.
  • You could be injured if you’re unfamiliar with electrical systems and gas lines.
  • You may void your warranty.

Always prioritize safety and hire a qualified plumber at Thousand Oaks Plumbing for these situations, or you could find yourself paying more on the back end to address more extensive problems.
