Unfortunately, we do not offer rebuild kits for sale. This decision has been thoroughly discussed with my father, and we have reached the conclusion that it is not in our best interest to sell them. The primary reason for this is that we have advanced equipment at our facility, enabling us to perform proper testing on the pump(s) after a rebuild to ensure they are functioning optimally. In the past, we have encountered numerous situations where customers attempted to reinstall the kit themselves, only to face pump failure later on. By handling the rebuild process ourselves, we can guarantee the quality and reliability of the refurbished pumps we provide.
