    Damaged Goods Policy:

    Damage to product(s) is not always easily identifiable, as damage can either be visible or concealed. For visible damage, do the following:

    • #1 Best Option: For the simplest solution for shipping damages, follow this procedure when receiving a delivery. This procedure is the standard operating procedure of the delivery insurance issued by all shipping carriers:
      1. Inspect your merchandise thoroughly for damage immediately upon arrival (delivery)and reject the entire shipment if you find any damage. Ask the driver to wait while you inspect the merchandise. 
      2. If you find any damage, do NOT accept the delivery. Doing so will expedite the process of  Humboldt Water Systems getting another unit out to you immediately. Refusing the shipment will protect you against having to pay the return shipping.  All shipping fees are always the responsibility of the purchaser.
      3. Immediately file a damage claim with the delivery carrier on the same day as the delivery. Try to take a digital photo of the damage if possible. After filing the damage claim, contact Humboldt Water Systems immediately at orders@humboldtwatersystems.com   for assistance and further instructions.
    • Legitimate damage claims will be promptly processed. A replacement from the manufacturer will be shipped to purchaser.   When the manufacturer receives the "damaged goods", a detailed analysis of the damaged product claim will be performed to determine if the product was damaged during transportation. 
    • #2 Option:If driver of carrier has already departed, or has left , contact the delivery company the same day and file a damage claim.  Then, contact Humboldt Water Systems that same day at orders@humboldtwatersystems.com for assistance and further instructions.  The manufacturer or delivery carrier will initiate a paperwork process and instruct you to send the goods back to the manufacturer, sometimes at your expense, until the damage is inspected.   All shipping fees are always the responsibility of the customer.  When the manufacturer receives the "damaged goods", a detailed analysis of the damaged product claim will be performed.
    • If you have a digital camera, take a snapshot of the damage as proof/evidence before it departs and E-mail the photograph to us as soon as possible.
    • E-mail correspondence and photos to orders@humboldtwatersystems.com

    Concealed Damage

    Sometimes damage during shipping cannot be detected until product(s) is removed from the packaging and installed. If concealed damage is detected, it is very important to act immediately. Purchaser needs to contact the carrier, file a concealed damage claim, and contact Humboldt Water Systems at orders@humboldtwatersystems.com The product(s) needs to be shipped back to the manufacturer at purchaser’s expense, so the manufacturer can inspect product(s) to determine if damage occurred during shipping, during installation, or after installation. Photos are most helpful and can also be e-mailed to orders@humboldtwatersystems.com
