Registration
Register within 90 days at reliancewaterheaters.com or by phone. Without registration, warranty starts at manufacture date — losing up to 6-12 months of coverage. Have your serial number ready (first two characters encode manufacture year and week).
What voids the Reliance warranty
- No anode rod replacement — once consumed, the steel tank corrodes; this is the #1 warranty denial
- Non-licensed installer in jurisdictions requiring permits
- Improper venting on Power Vent or atmospheric units (back-drafting, undersized vent)
- Wrong fuel connected without LP conversion kit
- Commercial use on residential-rated units (kicks down to 3-year)
- No water filtration on hard or aggressive water — anode consumed in 1-2 years
Reliance vs State warranty
Identical tier-for-tier. Reliance 6-NORT = State ProLine = 6 years. Reliance 9-NORT = State ProLine Master = 9 years. Reliance 12-50-NORT = State ProLine XE = 12 years. Reliance Hybrid HPHE = State Premier Hybrid = 10 years.
Bottom line
Register inside 90 days. Same warranty as State, AO Smith Signature, and Whirlpool equivalents. The Hybrid 10-year is the longest standard tank coverage in the lineup. 12-50-NORT Premium 12-year is competitive with Rheem Performance Platinum and Richmond Premium.
