If a hose gets clogged it is not a hose failure. It is do to an obstruction being allowed to pass from the larger hose to the whip. It could be paint breaking from the sprayer hose, a rock by-passing the filter, coagulated paint, or one of many other reasons.
It is not a hose failure just because it is clogged. It may not be usable anymore but again it is not failure of the product. It is from allowing, be it an uncontrollable or non control act, an obstruction to enter the whip. The ExitFlex whip is a very small diameter whip designed for thin products.
We do not warranty hoses that are clogged as it is always related to improper use, controllable or uncontrollable. You need to clean your pumps daily. Do not let set overnight. Always strain your paints. In winter a hose that freezes will be clogged forever. Not understanding what materials can flow through a small ID of a whip will end in clogs.
