I purchased a weldless bulkhead from Bargainfittings. About how high should I install this on my brew kettle? I also got the whirlpool adapter. Using 15 gallon pot, it was getting a little to heavy to lift all of the time.
I put mine about 2" up as well, since it made for a nice formed diptube length. The problem I have is that using the Bargain Fittings sightglass, 5 gallons doesn't even show in the glass. My sightglasses are for 10 gallon batches only. This hasn't ruined any beer, but I was hoping to be able to use the sight glasses, but to get any volume accurately, I need to measuring cup it.
The moral, if you are ever going to share the bulkhead with a sightglass, put it as low in the kettle as humanly possible.
I did like the instructions stated by placing the washer at the bottom weld and marking the hole. This is pleanty of room for a dip tube and if you do the same for your sight glass it will read at about the 3 galon mark.
