A:Answer Hi there,
Thanks for your question. This pressure washer is designed to be connected to a standard garden hose and pressurized water supply. It is not intended for gravity-feed operation from a bucket or tank.
The unit is designed to self-prime once it is properly connected to a water source and the system has been purged according to the operating instructions.
If you have questions about a specific water source setup, please contact Greenworks Support at 1-888-909-6757 or through live chat, and our team will be happy to assist.
