Good to know

This pump is designed for clean water only—avoid using it with saltwater, chemicals, or debris-laden water. It features a standard 3/4" G-thread connection, compatible with most garden hoses and fittings. As a bare tool, it requires a Ryobi ONE+ 18V battery and charger, which are sold separately. The pump is not submersible; place it on a dry surface near the water source. For best performance, keep the suction hose as short as possible and ensure all connections are airtight.
