I would like to know what the white valve is on the end of cooling pump for the a/c sea water cooling pump. It's a hunter 42ac 2006 model

I would image its to bleed air out but I have never had to do that on mine. Same exact boat.

Strange. Only thing I can think of is the PO installed it to bleed coolant water for winter layup.
Thinking more about it I don't like it. Seems like a potential open to sea path. Were me, I would remove the stopcock and replace with a seal.

Thinking more about it, aren't there two A/C systems? I have a T on my pump and it feeds each A/C system from the same raw water pump. Perhaps they added a second pump and left the T and the ball valve in case they needed to put the second A/C back on the original pump.
