I have a compressor and I would like to get the large plug unscrewed. It won't budge. Is using heat a no no? MY intuition says no no.

 

Is that a drain plug? A impact mite loosen it with on low air sitting use a good tight socket so it don't round it off.
Orich

 

So that is a large air tank for a compressor? You want to get that large reducer out of it? Some heat would work fine. Just don't melt it!

 

Yeah the little hole is where the drain petcock screws in. I want to take out that large plug in the pic. I just want to clean out any crud in the bottom of the tank. Or should I just leave it alone?

 

Probably just rusted in place from the condensation. As long as the tank is empty, looks like you already have the drain out, go ahead and warm it up with a torch.

 

and be sure to have tank "open" when using heat !!

 

Ah, ya, so it's the bottom of the tank(I was having trouble figuring that picture out). That makes sense and I agree, likely kinda rusty and will be tough to get out without heat. I thought it was a end hole(horz tank) and more likely to not be rusty.

 

Is something broken? Are you trying to fix something that is not?
If not, leave it be.

 

Nothing broken. Just thought getting any crap out would be good. I think I'll take your advice CJ unless it starts clogging the pet ****. The old one leaked a tiny bit so I bought a new one ( petcock ). Thanks guys, Todd.
