Reply To: How many lbs of pressure is there when a double line pressure tank is in use?

What a cool tank pressure gauge! You patent it yet?

Jeff, they can build up pressure from the sun here also. I’ve seen lots of relief valves fail to hold sufficient pressure, but never seen one fail to blow off excess pressure. Not that I’m aware of anyway. Boom ????? Good reason to junk rusted tanks.
