Tip - Air Compressor Drain Valve

The other week I went to drain my air compressor for the first time in a few months. Now the manual says I should be doing this every time I use the air compressor so my maintenance habbits are clearly pretty shit. But with so much crap in the way and the drain vlave located all the way in the bottom of the tank, I just couldn't be bothered (how lazy IS this guy?).

To make draining the air compressor a bit easier, I decided to make an extension for the drain valve which would locate it to a more convenient location so that it could be accessed without any fuss.

I threw out all my SAE tools so the 15mm socket didn't work, which is why I keep an adjustable wrench for just such occasions

Out comes the old valve

A quick trip to Princess Auto produced some 3/8" air compressor fittings and a ball valve

Mix in some teflon tape...

...and we're done

Perfect ground clearance!


Now I can drain the compressor by simply opening the ball valve just under the front of the compressor. No more lifting :)


This setup is pretty easy to use and any moisture that does build up inside the compressor will drip into the elbow fitting instead of sitting in the bottom of the compressor. When the day comes where I can't be bothere do bend over to turn a valve (just a matter of time), I'll think about relocating the valve or building some kind of remote switch.

  1. You definitely know your way around things! How did you end up with that idea? Does that drain valve have the same feature as a draincock? Also, smart choice going for the brass drain valve. That brass valve will definitely last long because it’s pretty resistant to moisture. Gayle Manning

  4. Your blog is very informative. Eating mindfully has been very hard for people these days. It's all because of their busy schedules, work or lack of focus on themselves. As a student I must admit that I have not been eating mindfully but because of this I will start now. It could help me enjoy my food and time alone. Eating mindfully may help me be aware of healthy food and appreciating food.ถังลม
