Strainer’s clean, no air, CHW supply steady – but the coil just starves the second flow drops.
Feels like a valve authority issue or bad circuiting, but curious if anyone’s seen this exact behavior.

Voltage and cap are spot on, but the RPM is clearly low – head pressure starts creeping up way faster than it should when load picks up.
