Warranty Information

GROCO will repair or replace, at its discretion, any part of any of its products which is determined to be defective by the factory (or by an authorized GROCO service center) within one year* of the O.E.M. installation date or the distributor's original date of sale provided that:

  1. The product has been properly installed and used in accordance with the instructions packed with the product.
  2. No repairs or replacements have been made without written factory authorization.
  3. Proof of purchase can be supplied (receipt or invoice)
  4. The product is under original ownership.
  5. The product is properly packed to prevent shipping damage and shipped freight paid directly to the factory (or delivered to an authorized GROCO service center).
  6. The product has not been misused, abused, or altered in any way. 

GROCO products are designed and manufactured with the most durable materials available for resistance to the corrosive and electrolytic effects of salt water application. This does not mean, however, that the product will last indefinitely without proper care and maintenance.  GROCO recommends regular weekly inspection of all parts of its products for signs of wear and/or deterioration of any kind, and replacement of worn parts with genuine GROCO parts. Failure to inspect regularly and/or replace worn parts when necessary constitutes neglect on the part of the owner, and could cause failure of or damage to the product, or to the vessel, of which the product is a part. Neglect voids product warranty.

The following conditions are not covered by this warranty:

  1. Repairs or repair labor performed by other than factory personnel, or authorized GROCO service center personnel.
  2. Damage to the product due to use to perform duties other than those for which the product was intended.
  3. Damage to the product due to the introduction of chemicals not intended for use with the product.
  4. Damage to the product due to winter freeze-up or improper winterization.
  5. Damage to the product due to use under extreme temperature or pressure conditions.
  6. Damage to the product due to jamming or clogging with foreign matter which the product is not intended to handle.
  7. Products found to be operating properly by factory personnel or authorized GROCO service center personnel.
  8. Physically damaged or altered products.
  9. Frayed motor leads.
  10. Products with missing or modified labels.
