One of those "oh, yeah" moments...

[Bulin's Milker Bucket Brews]

After several attempts at spunding with the all rounder and not being able to hold more that 5 psi....

Finally realized the preasure relief valve wasn't quite screwed in tight...and I was like "oh, yeah" that explains it.

Ouch
I may have the opposite if I am not careful.
I got my spunding valve (with digital gauge) screwed tight so I can use it as a pressure gauge...

Mine won't regulate for crap under 5psi. Just leaks out.
