Warranty

We feel that being honest is a much better policy to win your trust rather than trying to lure you with nearly impossible statements such as lifetime warranty. Nothing lasts forever! Our warranty policy is simple; we offer a 3 year warranty on everything we sell and 10 years on our collectors. With this warranty you will get NO hassle next business day replacement (if shipping service and inventory permits). However, as a valued customer you will get technical support through the lifetime ownership of your product. Our Collector do carry longer warranties 10 years from the manufacture. The warranty cover failures that occur during normal operational conditions or manufactures defects. It does not cover failure due to inappropriate operation such as freezing or over heat. Damage caused by vandalism, storms, floods etc. Your houshold insurance should be modified to cover the system from such situations.
