Works well enough
I like it, but maybe I'm just installing it wrong. Since there's nothing on the inside of the kettle for me to grip with a tool, I had to use a lot of teflon tape to ensure the ball valve would not leak. Other than that, I like it.

Could this set up be used as a whirlpool port?
Josh on Aug 22, 2016
BEST ANSWER: Sure it can. Obviously it would require a method of connecting a pump hose to the threaded end.. in my case I use a 1/2 " male Cam lock fitting and connect the hose with female ends from the pump to the fitting. I installed mine at the top to create the whirlpool at the height of my boil. Hope this helps.
Just received the Iso flow bulkhead with dip tube. The dip tube does not fit into the bulkhead. Did I receive the incorrect sized tube?
P S on Nov 25, 2015
BEST ANSWER: I lubed the perimeter of the tube with keg lube and pushed it in to the bulkhead with the pre fitted o rings in place. one end of the tube inserts easier than the other.
What is the size of the outside connection? Will a 1/2" NPT Female fit?
H E on Oct 19, 2015
BEST ANSWER: That is 1/2" NPT threads on this bulkhead. 1/2" female NPT fittings will fit.
Should the ball valve be flush with the fixed nut?
F A on Apr 30, 2016
BEST ANSWER: It's not necessary for it to be flush, just thread it on as far as it will go.
Is the diptube included with the bulkhead or do you need to order it separately?
N S on Feb 8, 2016

Thank you for choosing Northern Brewer! The isoflow single piece bulkhead includes the dip tube. I hope that this helps, have a great day!
What size hole will work for this bulkhead: 13/16", 7/8", or both?
J M on Jan 23, 2016

Thank you for choosing Northern Brewer! You will need a 7/8" hole for the isoflow bulkhead. A 13/16" hole will be too small. I hope that this helps!
What is the vertical length of the dip-tube from the center of the bulkhead to the bottom of the dip-tube / How high ( above the bottom of the pot ) would I need to center punch for the bulkhead hole to have the dip-tube be 1/8" - 3/16" off the bottom of my pot?
Are the vertical measurements identical for the Isoflow Bulkhead and the EZ Clean Bulkhead ?
John A on Jan 10, 2017
BEST ANSWER: It is the same dip tube in those other assemblies. The 7/8" diameter hole we punch has the bottom of the hole at 1 and 3/16" from the bottom and 2 1/8" at the top of that hole. That puts the dip tube at exactly 1/8" off the bottom. If you can replicate that measurement, we use a jig to hold the kettle to the perfect location then punch the hole. My math works out to the pilot hole that you drill being at exactly 1.66 inches off the bottom but I would double check that! Measure twice, drill once!
How long is the Nipple? And is it a straight through or close?
Gilbert H on Feb 17, 2016
BEST ANSWER: The overall length is 2" with a fixed nut in the middle. The portion that goes through the kettle wall is 15/16" long and the threads are 5/8" NPT. The portion that is outside of the kettle is 13/16" long and the threads are 1/2" NPT for attaching a standard ball valve.
It appears that all the reviews listed for the IsoFlow Single Piece Bulkhead are actually reviews for siphon tubing. Where are the bulkhead reviews?
N S on Feb 11, 2016
BEST ANSWER: Thanks for contacting us Lou. I have forwarded this issue to our web team and they are working on a solution.
How is it beneficial to get within 1/8 of the bottom of the pot? Wouldn't it be fully surrounded by trub this close to the bottom of the pot?
Andrew G on Nov 2, 2015

If you do a short 5-10 minute whirlpool at the end of the boil by stirring the wort for a minute or so and letting it rest the trub will form a nice cone in the center of the kettle and you will be able to draw clean wort from around that cone. A bit of trub int he fermentor is normal but you can leave most of it in the kettle and leave minimal liquid behind this way.
