Ted,
Thanks for the advice, I'll put a relief valve on the line tomorrow and see how low I can get the pressure and still get sufficent bubbling to keep the ice open.
The compressor dosen't have any labels on it, that I recall, and is pretty small in size. It just fits into the well house along with my small well pump.

I really appreciate all the feed back from you folks. This is a great site and has helped me many times with my questions.
