It seems that Empty pipes will block the flow of new material. Specifically, I'm having this problem with cleaned water from the Desalinator at the moment but have had issues with it with the water sieve. included two pictures. I've tried deconstructing and rebuilding to no avail. sometimes if I empty a pipe after the point of the issue it will clear but not always.
Steps to Reproduce
build pipes. Seems to be after some form of refinement?
