Items can be returned within 30 days of the date of receipt. They must be in new, unused condition. For this reason, we encourage customers to give the system a dry run (without water) to understand operation and each of the different components. Shipping charges are non-refundable. In the event of a return or if a package isn't deliverable by a carrier - only the cost of the merchandise is eligible for a refund. Please contact us with any questions about our policy or to initiate a return: orders@solis.nz
