Wow! Yeah, I’ve got a checklist I run nightly before I close the shop up:
1. Inside air line ball valve: OFF
2. Inside water separator: Drain, relief pressure in lines
3. Outside: Tank drain valve open - drain until empty
4. Outside Compressor: OFF
In the morning, it’s the same thing:
1. Outside: Tank drain valve open - check for moisture overnight
2. Outside: Check tank pressure, turn on compressor
3. Inside: Slowly open air line ball valve and monitor line pressure
4. Inside water separator: Drain, check for moisture.
I call it my “IN and OUT” check. Sort of like the burger place, but not as greasy!

If there’s a rupture in the line or anything, I can catch it right away. Blowing the line and tank out each night gets the main moisture out, then in the AM, gets the remaining moisture out due to cooling condensation. Been very fortunate in the DFW area it’s nowhere near as humid as Houston was, and my tank doesn’t get a whole lot of moisture in it. We’ll see how that goes on the first large paint job I do. That’s the real test. Blasting and using air tools hasn’t really yielded any large moisture issues so far.
So crazy, and scary, to see things like this happen.
Cheers
