Mark Mandell - Gone Round In New Jersey
It's good that you vent your tank to purge the condensate; lot of people forget to do it and wonder why their tanks rust out and fail. I also did that manually for a while until I found the auto-valve. Now the only thing I have to remember is the once-a-year clean and lube. If we leave the house for more than a few hours I always flip the switch on the compressor so it won't run. Friend who hangs out here lost his entire shop when his compressor's unloader valve stuck forcing the machine to run continually which over-drew his electric service that arced and set the building on fire.
Tooling along at 75 when the 18 next to you vents his tank can scare the snot out of you if you don't know what the noise is.
