Common questions about manuals, registration, and support for this brand.
AMTROL products involve pressurized systems that can cause serious injury or property damage if mishandled. A licensed professional ensures the product is sized, installed, and sealed correctly according to safety codes.
If you notice signs of corrosion or leakage, contact a qualified professional immediately. Corroded tanks can burst or explode under pressure, so they must be replaced rather than repaired.
It is recommended that a professional plumber inspect the complete system, including the expansion tank, at least once a year to check the pre-charge and structural integrity.
Warranty terms vary by model (e.g., 1 year for some SX models, 7 years for others). You can verify your warranty eligibility and register your product on the AMTROL website under the Warranty section.
