How do I vent a 55 Gallon Drum?

[Reddcow]

I am new and don't know the best place to put this.

How can I vent a 55 gallon drum with water in it? It is a closed top drum with two bungs. Thanks.

Remove one of the bungs.

Drill a bunch of holes in the lid.

Need a drain hole ?, I got an idea for that.

OK, Lets be a little more specific. EXACTLY, what kind of vent you thinking about?

 

[Reddcow]

I'm not sure what type of vent, just a vent for the air, so the drum doesn't collapse in on itself. I can't remove one of the bungs because the drum will be on its side. So water would pour through the other bung if I did that.

We better back up, what are trying to do ?

Why would the lower bung be open ?

It's a simple solution. Screw a 3/4 street elbow into the upper hole. Extend with a short length of pipe ( 3 inches)over the drum. If the 2" hole is on top, you'll have to use a reducing bushing/s

Seen alot of bung hole caps with a 3/4 tapped pipe hole.

we use drums of concentrated coolant at work and just put a ball valve into the 3/4 hole, tip up on the stand and just crack the 2 in bung a little so it will suck air when the internal vacuum rises. once the level gets down it's easy to crack it some more. the valve allows easy filling of small pails to dump into the machines.
