Multifunctional Liquid Siphon transfers liquids between containers, suitable for fuel, gasoline, water, and other liquids. Eliminates the need to start the siphoning process by mouth or lift heavy tanks. Siphon pump features a 1/2 inch valve and PVC hose. The valve and tube are secured with a hose clamp to prevent disconnection. Designed for water and fuel transfer. The hose can be cut to desired length. Includes a one-way valve for efficient transfer. Fast flow rate of up to 3.5 gallons per minute. For proper operation, the liquid level at the suction end must remain higher than the discharge end during use. Not intended for use with drinking water or food-grade liquids. To prime the siphon, shake the valve vertically (up and down) to initiate flow.
