If the regulator was purchased from an authorized mares dealer, you are the original purchaser w/ receipt of purchase, regulator has been maintained at the recommended service intervals determined by Mares, record keeping of the service intervals is intact, and lastly, the service is performed by an authorized Mares dealer, the poppet would fall under the parts policy. It is very possible, the tech, and or dealer was not aware or forgot about the policy. We also cannot mandate the dealer follow the policy. Note: this does not cover labor costs of the dealer to service the equipment. Only applies to the parts.
