【High flow rate and time saving】 2 meters long thick transparent PVC pipe. Oil-resistant, high-temperature resistant and corrosion-resistant. The large diameter pipe can pump liquid faster, and the pumping speed is 10L/min. The regulating valve can adjust the size, switch the water flow, and act as a link. You can also connect other pipes of the same size to it if you think the pipe is not long enough. 【Easy to use】 Press the pump 2-3 times to extract the liquid. The built-in check valve can effectively prevent the liquid from flowing back. The enlarged and non-slip rubber ball has a stronger oil absorption capacity. The arrow on the pump body makes it easy to identify and understand the direction of water flow. Package Includes： 1 * 2M Liquid Water Transfer Pump with Check Valve. Flow Control 1 * 16mm Through Valve Notes： 1. The liquid you want to pump must be higher than the incoming bucket. 2. The connection end should not only be on the surface inside the liquid. 3.
