Tools needed before undertaking this task:

Bent circuit piping prevents correct flow of water cooling: correct flow must be restored to regain complete
control of extrusion process.
If bend is happening anywhere in the printer BUT NOT at the extruder block:
1)
Remove bend, re-seat piping
2)
Test water flow
3)
Clean cooling circuit
If bend is happening at the extruder block (WE ASSUME THAT MACHINE IS FULLY DRAINED):
1)
Remove extruders
2)
Detach piping (if pipes were fully seated, they will need to be shortened later on)
