The majority of our equipment is covered by a limited one (1) year warranty. Internal components (electronics, pumps, manifolds, etc) are covered by this limited warranty for one (1) year. External components (hoses, adapters, wheels, couplers, etc.) are covered by a ninety (90) day limited warranty. Abuse, of course, is not included. The Advantage Flush System is the exception with a two (2) year limited warranty on internal components.
