Growmax Water™ filtration systems come with a one-year warranty which protects against manufacturer defects on all components. The warranty does not include obstructed filters due to the lack of regular maintenance or due to excessive sediment or chlorine in your water. The warranty also does not include damage to the unit from use outside of normal grow and garden installation parameters, or due to not winterizing your system. You can return your product unused in its original packaging for up to 30 days from the date of purchase. Customer must pay for return shipping cost.

Because of the size, weight, and shipping cost of Growmax Water filtration systems, there is no need to return any unit that may have a damaged component. All components can be easily replaced. Please contact us with a photo of any damaged component and we will immediately send out your replacement part.

Please contact us to request a return authorization at: [email protected]

Upon receipt of the returned unit, GrowMax Water™ will issue credit for the purchase amount, minus a 20% restocking fee.
