Update: My coolant pump issue turned into a three day nightmare

I mean, it started with a simple low pressure alarm on a Haas VF2. I checked the filter and sump, all clear. Spent a whole day thinking it was the pump itself, even ordered a new one. The real problem was a tiny piece of swarf stuck in the solenoid valve on the pressure line, which I only found after taking the whole manifold apart. Has anyone else had a coolant flow problem that wasn't the pump or filter?

Ugh, I've spent way too much time chasing coolant ghosts myself.

Found a chip in the bypass valve once.
