This innovative blow out plug allows you to winterize by simply hooking up your home air compressor with a common female quick connect on your air hose.
Set 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. It is a one-person operation!
This plug does not work with Schrader style air chucks like on a bicycle pump. See VTS-671 if you want to use that style.
