Bison Pumps are manufactured in the U.S.A. with the highest quality materials. They are designed for a lifetime of use, and therefore come with a lifetime warranty. Bison Pumps are the finest hand pumps on the market with Stainless Steel components, competitive pricing, and expert advice.
If you suspect a defect in your Bison Hand Pump, please contact us at 1-800-339-2601. We will need as much information as possible in order to determine the cause of the problem. Please be ready to provide photos or any other information that will be useful in determining whether the pump has a defective part.
If the problem is determined to be due to a defective part, Bison Pumps will issue the customer an RMA (Returned Materials Authorization) Form which must be included in the packaging when returning the defective part. Bison Pumps will provide the customer with a shipping label and will determine the mode and type of shipment.* Once the returned materials have been received and the part is confirmed defective (and not abused), Bison Pumps will issue a credit or replacement.
*Customers outside the U.S. will be responsible for shipping costs when returning a product.
Not Covered by Warranty
Regular Wear Parts are not included in the Bison Pumps Lifetime Warranty. Bison defines a Wear Part as one whose expected lifetime varies depending upon the amount of use.
Physically, every hand well pump has a limited depth from which it is feasible to draw water. Bison Pumps does not recommend trying to hand pump water from a static water level of 350 feet or more. This depth is not practical when considering the amount of pressure required to lift the water in relation to the amount of water that will be produced.
Bison Pumps provides extensive technical support and education on our hand well pumps. An Owner’s Manual is included with the purchase of a pump system. Also, the Education section of the Bison Pumps website is continually updated with new articles and has a library of technical documents. You are always welcome to call us with any questions at 1-800-339-2601.
Please be aware that the Lifetime Warranty is contingent upon proper installation, use and maintenance of the Bison Pump.
