With this brass blow out plug, you can winterize your trailer by attaching an air compressor with a Schrader-style chuck on the air hose, like at a gas station. Unless your chuck has a clamping feature, it requires a person to hold the chuck onto the plug while in operation. Keep your air pressure at 45 to 60 psi and open faucets. You'll still need some nontoxic antifreeze to complete the job, but this will make it a lot easier and faster.
