kettle tap position

[JR]

I’m going to get a tap and a thermometer put into my 65 litre kettle sometime soon.  Question is, how far up from the bottom of the pot should I put the tap.  I guess I
should do it based on volume below the tap.

 Would a 7 litre (about 10%) dead space below the tap be about right?

Sounds about right - once you've run off enough to see what's going on you can always tilt the pot to get any remaining wort out if you're still above the trub.

Mines about 7L up for a 20L batch. But I also have a pickup tube that's relatively easy to adjust before I fill my kettle. I leave around 3L of trub in the kettle./

On my 56 Litre boiling pot I put the centre of the tap 35mm up from the bottom of the pot. I never have any problem draining trub into the fermenter. I need to tip the pot to get the last drop of wort out. I always use Kopafloc to coagulate the proteins and do a double batch sparge, running off the wort until it runs clear to reduce the amount of crap in the boiler. I've just upgraded to an 80 litre pot with the intention of doing double batches. I've put the tap 45mm up from the bottom which I hope will be enough allowing for the larger pot diameter. Hopefully first double batch Scotish Ale this weekend.
