Reversing The Motor Direction To Drain A Sample

I’ve attached a video of the nearly finished water sampler’s ability to drain a sample without disconnecting the bag from the system. The current system is not proven to be air-tight and should not be expected to be so, but this will help to reduce error and eliminate the need to disassemble the tubing. Instead, the user can specify which bag to sample and run the pumps in reverse through serial commands through a computer console.
