Auto tank drain

What part broke on you? Is the valve causing the issue or is It the tubing and connectors?

It was the valve. They seemed to corrode and stop working. The electric one has been in place for many years and for whatever reason has not suffered from the same problem. The compressor is electric so power was not a problem and the laundry tub was right next to the compressor so running the drain into the plumbing drain also worked out well.
 
A couple months ago I replaced a huge and ancient shop compressor (left by the previous owner) with a 60 gallon Husky. I'd seen a thread that mentioned using an Omron timer to kill power if the compressor ran overtime. This did not seem necessary for my installation, but I did look into timers. Decided to cobble up an auto drain. The attached schematic shows how I did it. The ball valve that opens the drain is a "special" one I found on Amazon. It runs off DC and (somehow) stores enough juice to re-close after power is turned off. Here's a link to it:

Admittedly, the ball valve is a potential failure point. If it fails to close, the compressor won't shut off. But so far (6-9 months?), it's worked reliably. The valve body and ball are stainless and the ball seat is teflon.

Thanks. I ordered one of thoses Bendix DV-2 knock offs that Bob mentioned from EBAY

Hi Aaron,
How has the knock-off valve held up?
I have a new compressor coming Monday and want it to last.....safely.
Any feedback is appreciated.

It seems to not have enough storage capacity between runs and I have to manually empty it occasionally especially in humid summer weather. I suggest you look at something else. I'm thinking something on a timer.

The one Larry4406 posted looks like a high class (and dollar) version of the truck drain
 
I just mounted a manual valve on the side of my workbench right next to my vise. Cheap, easy and foolproof....

I have a manual ball valve that is plumbed into may water softener drain. It has become second nature to hit it every few days, but I live in a pretty dry climate. Mike

Except, for me, it's the tank I'm worried about and want to drain.....and my tank is on the floor.

.....and for me "foolproof" would have to be "automatic".
