Why do Waterous service parts drawings only show reference numbers instead of part numbers?


For many of the parts indicated with reference numbers, there are multiple parts that may be used. We use the serial number of the product to determine how the product was built and which part number applies to the particular product. Also, this is one of the reasons why we require a product serial number in order to provide part numbers and pricing. Also, this helps ensure you will get the right parts for your product now and in the future.
