But they do have it.If they could somehow change up the ValvoMax to also allow you to drain straight from the valve I think it’d be more versatile. I do like that there’s an extra cap over the valve, but Fumoto die hards would probably say that’s never been a problem they’re probably just not confident in their valve design.
That's how I ordered mine.
