Our Sunnyvale Noritz Installer Process
Reach Code + Rule 9-6 check + Noritz scoping
Every Sunnyvale tankless quote starts with One-Stop Permit Center Reach Code applicability and BAAQMD Rule 9-6 compliance. Noritz NRCP and NRCB are on the 14 ng/J compliant list — we confirm the SKU before quoting.
GPM sizing + Cal Water descaling plan
For a 2-3 bath Cherry Chase home the NRCP111-DV delivers 11.1 GPM at 35°F rise with built-in recirc. Cal Water Los Altos Suburban 12-17 gpg drives an aggressive descaling contract — non-negotiable to preserve the 25-yr HX warranty.
Install to Noritz + Sunnyvale code
Wall-mount NRCP or NRCB, install isolator service valves, route PVC concentric vent per Sunnyvale One-Stop checklist, upsize gas line if needed on Cal Water service, and file the City of Sunnyvale permit.
Commission + register 25-yr warranty
Run combustion analysis, program recirc schedule, register the serial with Noritz within 30 days to activate the 25-year heat exchanger warranty, and schedule Sunnyvale inspection.
What we do on the job
Sunnyvale Noritz installs run a different checklist than San Jose — Reach Code narrows the retained-gas scope, Rule 9-6 narrows the compliant SKU list, and Cal Water 12-17 gpg compresses descaling intervals.
- Confirm Sunnyvale Reach Code applicability with One-Stop Permit Center
- Cross-check NRCP / NRCB SKU against current BAAQMD Rule 9-6 compliant list
- Verify retained gas service and B-vent chase on the specific permit
- Size NRCP111-DV vs NRCB Combi vs EZ98 by fixture and hydronic load
- Verify PVC concentric vent path per Sunnyvale Fire Marshal checklist
- Install isolator service valves — mandatory for 25-yr warranty
- Upsize gas line if meter-to-appliance run exceeds Noritz chart
- Route condensate to indirect waste with neutralizer on NRCP condensing
- Schedule annual descaling reminder for Cal Water 12-17 gpg (hardest in South Bay)
- Register 25-yr heat exchanger warranty within 30 days

Sunnyvale — Frequently Asked Questions
Which Sunnyvale ZIP codes do you serve?
Every Sunnyvale ZIP: 94085 (Downtown/Murphy), 94086 (Heritage District/Cherry Chase), 94087 (South Sunnyvale/Lakewood/Serra Park), 94089 (North Sunnyvale/Moffett Park), and adjacent 94088.
Does Sunnyvale require a permit for water heater work?
Yes. The City of Sunnyvale One-Stop Permit Center requires a plumbing permit for water heater replacement and installation. Sunnyvale inspectors are particular about T&P discharge termination, expansion tanks on closed systems, and seismic strapping to studs (not just drywall anchors).
Do you cover Heritage District and Cherry Chase 1950s homes?
Yes. Heritage District, Cherry Chase, and older Lakewood Village homes commonly have half-inch gas mains and atmospheric-vent tanks in interior closets. Tankless conversions in these homes almost always need gas-line upsizing to three-quarter or one-inch to meet the 199,000 BTU combined load.
Is Sunnyvale water hard on water heaters?
Sunnyvale water is moderately hard, with blend variance across the city. Tank anodes typically need inspection at year 4 and replacement between years 5 and 7 in most Sunnyvale ZIPs; tankless heat exchangers benefit from annual descaling.
