*by J***Z on Reviewed in the United States on December 21, 2019*

What they "FAILED" to mention is that there is a long plastic probe on the relief valve and it is NOT as in the picture. I have to return it because I cannot use it.

I’m pretty sure this is the world’s best blow off valve!  Not sure why, I’ve never actually seen one work but I’m sure if it ever did blow it’d blow real good.
