Tustin CA — Annual Hard Water Service
In Tustin’s 15–19 GPG hard water, annual descaling is the single most important thing you can do for your tankless water heater. We set the reminder. We come back. We keep your unit running at full efficiency — and your warranty valid.

What’s Included in Every Annual Service Visit
💧 Professional Descaling (Core Service)
We circulate citric acid solution through your tankless heat exchanger to dissolve and flush calcium and magnesium scale deposits. This is what manufacturer maintenance guidelines recommend — but at 12-month intervals in OC’s 15–19 GPG water, not the 24 months written for national average conditions.
Duration: 60–90 minutes. Unit runs a full hot water cycle post-service before we leave.
🔎 Full System Inspection
Inlet and outlet filter inspection and cleaning. Condensate trap check (condensing models). Flow sensor check. Gas pressure verification. Venting inspection. Ignition electrode check. Error code history pull and review. We document everything and report any concerns in writing before we leave.
You receive a written service report with every visit — for your warranty file and resale records.

Why Annual Service Matters in Tustin Specifically
15–19 GPG
Tustin water hardness
Manufacturer guidelines are written for 7–8 GPG US average. At 15–19 GPG, scale accumulates at twice the rate. Their recommended interval is wrong for Tustin.
Year 2–3
When error codes appear
Without annual descaling, Tustin tankless units reliably show Navien E003 or Rinnai Code 12 by year 2–3. Annual service prevents these entirely.
15–20 Yrs
Unit life with service
Annually serviced tankless units in OC regularly reach 15–20 years of efficient operation. Unserviced units frequently need replacement by year 5–8.
Maintenance Plan FAQs
How often should my tankless water heater be serviced in Tustin CA?
Every 12 months. Manufacturer guidelines recommend 12–24 months nationally, but those are calibrated for 7–8 GPG water. In Tustin’s 15–19 GPG MWDOC supply, scale accumulates twice as fast, making 12 months the correct service interval.
Does annual maintenance keep my warranty valid?
Yes. Major brands like Navien, Rinnai, Noritz, and Rheem require hard water maintenance in their warranty terms. We provide a written service report with every visit to protect your warranty claims.
How do you set and manage the annual reminder?
We log your service date and send a text/email reminder 11 months later. There are no automatic charges or contracts — you confirm each visit before we schedule.
