Convenient Compressor Drain
Most compressor manufacturers recommend draining the tank after every use, and most compressor owners ignore that advice without serious consequences. Still, draining the tank is important, and the more often you do it, the better. As a compressor runs, water condenses inside the tank. That means rust. In extreme cases, you can even lose tank capacity. We’ve heard stories of tanks that held only half as much air because they were half full of water.
The twist-open drains on most compressors are pretty lousy. They’re hard to turn and easily plug up with rusty gunk until they can’t open or close properly. You can install a drain that’s fast, easy and reliable. Go to the compressor aisle at a home center and look for a ball-valve drain kit. If you don’t find one, go to the plumbing aisle to pick up a 1/4-inch ball valve, plus any 1/4-inch nipples and elbows you’ll need.
