Finally finished the new garage and put in a permanent air compressor. I'm thinking of taking out the cheapo drain valve it came with and running 3/8" pipe out the wall of the garage, with a ball valve inside that I can use to blow it out easily. Anyone have any better ideas?

The next step up is an auto drain so you don't even have to think about it. Check with a reputable compressor/air tool dealer /forums/images/graemlins/smile.gif

Mark Harbor Freight sells an auto drain for about 10 bucks. When I purchased a new compressor from Home Depot I installed one on the tank. When the compressor cycles off the drain automatically puges the water, it's a nice feature. It's also easy to install and does not require electricity itself to operate.

Sounds good to me, Mark. I don't have an experience with the auto drain systems; undoubtedly a good idea, but I know nothing of their reliability and durability. The ball valve is good, and another of our members plumbed his with one of the blow guns on it, so he can just use his toe to open the valve and drain the condensate.

I like that auto drain idea. I've never seen anything like that.
thanks

Yes, my setup has been on the compressor for about four years or so(that oil-less is still holding up, but LOUD). It continues to work fine(did I mention it is LOUD?).

To recap, I took that silly little valve from the bottom of the tank(60g upright). You know, the one that is under the frame, that is too small to get at for people older than 5? The one that sits right square in the middle of ideal black widow territory?

So while I was setting it up, I tilted the whole unit back. I took the liitle valve out, and put a pipe nipple in there. I put an elbow on that, and the a 6" piece of pipe poking out from under the compressor. At the end of the pipe, I put a regular old air nozzle/blower thingy madoogle. It is back far enough to be protected by the compressor, but just in reach of your toes.

When I finish for the day, unplug hoses, cleanup ect, I just lightly press on the air nozzle lever, and blow the water right out of there.

My old compressor rusted out(2hp 22gal horizontal) mostly because the silly drain was just to hard to get at...

Took two beers and $3 in parts.

Robert,

Great solution you have there! Do you per chance have any pics or a sketch of how you did this? I think I have the </font><font color="blue" class="small">( 2 beers )</font> part of it down OK, just need some of the tech detail.

Thanks for your input...

I would like to see the auto drain in a picture. I use a ball valve and it is a PIA........ junk.... /forums/images/graemlins/frown.gif

Junk I have attached a picture of the auto drain valve installed in the bottom of my compressor air tank. Note that I installed a T and then reused the manual drain that was in the tank when I purchased it. Note that I have never had to manually open the old drain since I installed the new auto drain valve.

The arrow points to the port where the water is bled from the system. The small flexible tube on the right is routed up to the pressure switch. The type of valve opens each and every time the the compressor cycles off, and it will keep your tank dry without thinking about it yourself.

Mike...... you know that I was going to ask this next question..... where is the picture of the plastic tube where it goes into the switch??? I need to know how this whole thing goes together. You are stunting my educational process by not providing the entire picture. Have you ever slept with a horse head?????????????? /forums/images/graemlins/grin.gif /forums/images/graemlins/grin.gif /forums/images/graemlins/grin.gif /forums/images/graemlins/grin.gif /forums/images/graemlins/grin.gif /forums/images/graemlins/grin.gif /forums/images/graemlins/grin.gif /forums/images/graemlins/grin.gif /forums/images/graemlins/grin.gif /forums/images/graemlins/grin.gif da junksta from Providence RI /forums/images/graemlins/blush.gif /forums/images/graemlins/blush.gif /forums/images/graemlins/blush.gif.....
