Leak test
When I look at a flare connection, I'm wondering what would be the best
way to test for a leak.?. A vacuum inside the tubing or pressure inside the line-set tubing?
With the shape of outer skirt of the flare, it seems like a vacuum would hold the tube tighter onto the tapered connector.
Whereas 200 PSI of nitrogen inside the line-set would be trying to force
the copper tube off the connector. (kinda like a one-way-valve).
And, nitrogen & 200 PSI gauges are cheap and easy to find.
If it held for a few days, that seems like it would be a pretty good test.
Comments please..
Thanks,
Rich
