That's just the pressure relief valve doing its job.

By chance was this valve on the indoor coil of a heat pump having a recip compressor?

Never seen that before. I would think there has to be an abnormal amount of virbration to shake these parts apart. I don't believe the complete weld would break popping off the power assembly.
Just a thought take a good look of the system. There may be somthing going on !

Having been a TEV product mangler in my past life, yes I've seen this before. It is not common, however. Originally Posted by jayguy

Normally this is not a problem for the valve.
But if a recip compressor is being used, and if the recip compressor is delivering an inordinate amount of discharge pulsations... these pulsations work on the TEV powerhead. The powerheat casing flexes ever so slightly with these pulsations as if it were a drum. The weld succumbs...
I don't ever recall this happening when a scroll compressor is used.The greater danger for most of us lies not in setting our aim too high and falling short; but in setting our aim too low, and achieving our mark. – Michelangelo
