ABSTRACT:
A siphon is formed of a long transparent main siphon tube having a distal end for insertion in a tank from which fluid is to be siphoned and having a proximal end. A smaller diameter transparent connection tube fits tightly within the main siphon tube at a proximal end but slides freely from the main siphon tube. An evacuating pump has a nipple connected to the inlet end, and the nipple fits tightly within a proximal end of the connection tube. After the distal end of the main siphon tube is placed in a tank, one pulls once or more on the plunger of the pump while gripping the proximal end of the main siphon tube and thus holding the connection of the main siphon tube and the connection tube. When fluid raises to a desired level in the siphon tube, a continued outward pull on the plunger past its normal limits and a simultaneous loosening of the grip on the proximal end of the siphon tube causes withdrawal of the pump and connection tube from connection with the main siphon tube, permitting the fluid to freely flow from the proximal end of the main siphon tube.
