Warranty information

Charles Austen recommends that all air pumps and systems are serviced annually. Although the air pump carries a 2-year manufacturer's warranty, diaphragms, valves and filters are consumable parts that naturally wear over time and should be replaced during routine servicing to maintain warranty compliance and ensure reliable operation.
