Our commitment does not end when you buy a Lungfish CCR product. We provide prompt and professional after-sales service to keep you and your gear in the water.

The Lungfish Dive Systems Ltd (“Lungfish” / “We” / “Us” / “Our”) one-year limited warranty is a voluntary manufacturer’s warranty (“Warranty”) provided to the first buyer (“Original Owner” / “You” / “Your”) of the rebreather unit (“Product”) and/or any associated parts (“Parts”) and accessories (“Accessories”). The Warranty applies to the Original Owner only and is not transferable. It provides rights additional to those provided by consumer law, including but not limited to, rights relating to non-conforming goods. As such, the Warranty is in addition to, and not instead of, any statutory rights provided by consumer law.

The Warranty is valid from the date of Product, Parts or Accessories purchase. Please retain Your original dated sales receipt for Your records. For warranty service of Your Product, Parts and Accessories, You will need to provide Us with a copy of Your dated sales receipt obtained from one of Our authorized dealers to confirm warranty status.

Product registration is an important step toward enjoying Your new Product, Parts and Accessories. Registering helps Us facilitate and provide warranty service support and advice and allows Us to contact You should Your Product, Parts or Accessories require an update or other service.  

Completed (signed and dated) liability waivers must be recorded on Our file for the Warranty to be valid.

All Products, Parts and Accessories are sold only on the understanding that English and Welsh Law exclusively applies to any Warranty claims including, but not limited to, product liability, regardless of where the Product, Parts or Accessories are purchased or where they is used. Accordingly, the courts of England and Wales shall have exclusive jurisdiction to settle such claims.

Procedures for Warranty and Service Work

All warranty work must be authorised by Lungfish before returning the Product or any of its Parts or Accessories for any reason. Contact Us by email or telephone for assistance and advice if sending any Products, Parts or Accessories.

If it is decided (in Our sole discretion) that a factory repair is necessary We will email a service/repair schedule.  This should be sent back to Us with the Product, Parts and/or Accessories and these should be returned directly to Our factory, with all relevant postage and insurance paid by You, together with a copy of the purchase receipt.

We are unable to determine if the Product, Parts and/or Accessories are covered by the Warranty until they have been inspected by a competent and approved person.

The recommended service and maintenance intervals are at 1 year, 3 years and 5 years. The servicing of the Product, Parts and Accessories can only be performed by a competent and authorised service technician. If such services are not performed at regular intervals, this may result in Your Warranty being null and void.

The individual service and maintenance intervals are based on normal Product use (192 hours per annum). In the event of more intense Product, Parts and/or Accessories use, these intervals must be reduced accordingly. It is therefore necessary to replace defective and/or worn out Products, Parts and/or Accessories immediately, irrespective of the maintenance intervals.

If modified Products, Parts and/or Accessories are returned for repairs or service and maintenance, then the Products, Parts and/or Accessories will be restored to their original format in the factory. Any additional Parts, Accessories and/or any remedial work required will be charged for.

In the event of repairs, only original replacement Parts and/or Accessories will be used. If other Products, Parts and/or Accessories are used by, replaced by, repaired by, or tampered with by any third party, including but not limited to modifying the gas flow direction, using Lungfish parts in combination with components from other rebreathers, use of different first stage regulators, use of underwater quick-disconnects on the solenoid feed, then the Warranty is null and void and We shall have no liability to You whatsoever for any injury, damages or losses arising out of or in connection with those repairs and/or replacements by a third party. There is a risk that such a malfunction could result in injury or even death.

Replacement Parts, Accessories, repairs and service and maintenance may only be carried out and will only be supplied if the Original Owner is able to provide verification that they hold and maintain the requisite Product-specific training.
