Syringe or extend the enteral feeding system that is used together of pipeline and provided with such as enteral feeding syringe or pipeline. System features are to balance the pipeline of interior pressure. The system includes that pipe has first end, the second end, exterior sidewall, position, first aperture and second aperture of the conduit in the pipe near the first end and the second end. Second aperture is located at the downstream in the first aperture, from the point of the end of conduit 1 point below to one along the length of conduit. This helps to mitigate certain undesirable pumping problems, and inhibits bacterial accumulation and growth. Prevent excessive negative pressure in pipe, in hole, pipe may include that contractile component is formed.
