When shipping product to a Service Center:

Product needing repair that is not under warranty may be shipped to a KZValve Service Center. Contact the Service Center in advance of shipping for instructions. If the product has been used, the Service Center may need a MSDS (Material Safety Data Sheet) document completed. All returns that have come in contact with chemicals require a Decontamination Statement Form for each product returned.
