All returned merchandise must be shipped via UPS or FedEx. Shipping charges paid on the original order are non-refundable unless the merchandise is defective. Customers pay all return shipping charges. Opened, unused merchandise may also be returned within 30 days of delivery if in like-new condition, subject to a 25% restocking fee. Once fuel or oil is added to engine-powered equipment, it is considered used and is not returnable. Returns are not accepted on custom and special order products.

Do I need a California-compliant pressure washer?

Yes. If you are using your pressure washer in California, it must be CARB compliant. California law requires that all pressure washers sold and operated in the state to adhere to strict emission standards set by the California Air Resources Board (CARB). The use of non-compliant equipment is subject to fines and confiscation by authorities. Purchasing a non-compliant pressure washer outside of California is not an option if you intend to use it in the state, as it will also need to be CARB compliant. PCE carries a complete line of CARB and EPA compliant pressure washers ready to go right out of the box and stay on the road. To learn all about California compliance, check your equipment, learn more about CARB and what they require, shop all compliant models, and even learn about financing options available to you, head to our California-Compliant Pressure Washers page.
