What is “auto check technology”? 

JDI’s Auto-Check Technology is exclusive to our self-evacuating oil drains. It utilizes a check ball in the bottom of the downtube to automatically seat up when shop air is hooked up to the drain. No one else’s drains work this way.

Auto-Check Technology eliminates the need for a large ball valve in the downtube. It also makes emptying the drain much easier for the shop technician. There’s no need to remember to close the ball valve when hooking up shop air. This avoids oil geysers that most shops have experienced at one time or another when using other self-evacuating oil drains.
