Tankless Water Heater Maintenance Near Brea, California
Tankless Water Heater Maintenance Near Brea, California
Stay ahead of error codes and cold showers.
Tankless (on-demand) water heaters are awesome for endless hot water — but only if they can move water through the heat exchanger at the right flow. Sediment, scale, and dirty inlet screens make the unit think there’s not enough water or too much heat, so it shuts down. Our service is designed to clean, flush, and reset performance so your tankless can keep up with your home.
We service many of the common SoCal brands: Navien, Noritz, Rinnai, Takagi, Rheem, Bosch, and others.
What We Do During Tankless Maintenance
- Verify model, fuel, and install location
- Inspect gas, venting, and condensate for safe operation
- Check for stored error codes / history
- Flush and descale the heat exchanger (to remove mineral buildup)
- Clean the cold-water inlet screen / filter
- Check flow rate and temperature rise
- Confirm recirculation or comfort features are working (if equipped)
- Show you how often to service based on your water quality
If we spot worn parts, venting issues, or undersized gas lines, we’ll tell you before doing additional work.
Signs Your Tankless Needs Maintenance Now
- Hot water cuts in and out mid-shower
- Unit shows repeating error codes
- Water is not as hot as it used to be
- It gets worse when two fixtures run at once
- You hear the unit trying to fire multiple times
- You haven’t had it flushed in 12+ months
- You’re on hard water and don’t have a softener
These are classic symptoms of scale buildup or flow restriction — both are solvable with maintenance.
How Often Should I Flush a Tankless Water Heater?
- Every 12 months for most homes
- Every 6–9 months if you have very hard water or lots of usage
- After big remodels where debris might have entered the lines
- When new error codes start appearing after years of no service
We can put you on a simple annual reminder so you don’t have to remember.
Add-On: Recirculation & Performance Tweaks
If your tankless supports it, we can check or enable recirculation, adjust temperature, and make sure you’re getting the best performance at distant fixtures — perfect for two-story and larger Brea homes.

Tankless Water Heater Maintenance FAQs
What happens if I don’t maintain my tankless?
Scale builds up, the unit overheats or can’t sense flow, and it starts throwing error codes or shutting down.
Can I flush it myself?
Some homeowners do, but professional service catches venting, gas, and sensor issues at the same time — not just scale.
Will flushing fix my error code?
If the error is scale or flow related, often yes. If it’s a gas, vent, or sensor issue, we’ll diagnose and repair it.
Do I need a water softener?
It helps a lot in OC. A softener or filter reduces how often you have to descale your tankless.
Can you maintain multiple tankless units in one visit?
Yes — tell us how many you have and we can service them together.
