So... There were no instructions in the box but if you look at the pump there is a red arrow above the "northern brewer".. I assumed that was the in side and it was.
The tubing slips over the flare and then you screw the black caps on.
It comes filled with some form of liquid... No idea what... Feels like very thin glycerin..
It says 1 gpm but I didn't time it.
Not too loud, better than I expected but it is a very small pump.
All plastic construction but it seems sturdy.
For the in tube I used an old non spring bottle filler and busted the black bottom off.
Has a switch in line which is nice.
The rubber feet have holes for mounting.
So far? I love it... It will save a lot of time and lifting using an auto siphon and hoisting up carboys filled with pbw or star san.
No idea how long it will last but I thought I saw claims of 30000 hours? I may be just remembering something else.
$50...so far I think it's worth every penny..
