I replaced mine with a 1/4" "T" fitting, close nippled to the tank, with a ball-valve on 1 side,+ a pull-cable drain off a Big Truck on the other side...
With the other end of the cable at the top of the unit,... No need to bend over anymore,...
If it Really needs drainin',... 1/4 turn of the valve,+ it's free flowin'...
Ayuh,... I finally got a picture of 1 of my airtank's drain,....
The end of the cable can be hung from anywhere it'll reach....
A little tug in any direction, Blows the tank dry...

Thats a pressure relief valve ,with a cable to pull,nothing electrical....I'm not sure about the portable compressors,but theres about three on a big compressor in various locations,I like this application,I'd have never thought of it...and if the compressor doesnt shut down for any reason the valve will blow at a predetermined pressure...a very good idea...

Ah, Nope,... Nothing electrical,+ Nope, not a pressure relief valve...

Read the text quoted above the picture...
It's a Remote Tank Drain for a Truck with Air Brakes....
The cable end is attached wherever it's convient to reach,...
(The cable on that particular tank is Twice as long as needed, so it's doubled back to the drain fitting)
Then a couple of tugs on the Cable drains the moisture from the tank....
The fitting closest to the camera is a simple twist valve for manual draining...

That's cool.

Besides the ease of draining the water, I like the idea that the pipe nipple and T fitting also acts something like a sump that'll keep small-ish amounts of water out of the tank between flushes.

my hf compressor had a 1/4" petcock removed that and added the ball valve as pictured but went one step furthur. at home depot right next to where you will find the brass fittings you will also find a 1/4" male x ptc adapter (push to connect) now get a piece of 1/4" tubing and when you want to drain the tank push the tubing in ,put the end in a bucket and open the valve. a day of the comp running down here in south florida easily produces a few ounces of nasty water .much neater going into a bucket than draining on the floor . when you are done push the tubing into the fitting to release it and roll the tubing up to store it
