I just setup my first w/c rig, testing for leaks at the moment.. most of the air seems to be out of it, but, the tubing after my maze4/before the pump inlet is getting sucked together. If I shut the pump off it goes back its normal round state. is this normal at all? Something I need to do to fix it? its 1/2id Tygon, not sure about the wall thickness.
