Brewfat will likely have his own answer of course, but after futzing about with some other solutions I just ended up getting one of these and threading it on the inside of my ball valve coupler. Drains my kettle virtually dry.
Just out of curiosity did you make your own diptube or did you purchase one. I haven't found one in any of my catalogs... I think it would need to be pretty short correct?
WOW! That is a simple as it gets answer to a dip tube! I'll be using one of these as a dip tube.
How high from the bottom of your kettle is your valve mounted? About 1.5" to center of valve mount hole to bottom of the brewpot?
Thanks again for that simple solution!!!
