The valve kits I see on-line go straight in to the kettle without any pick-up tube. Can you add a pick up tube to draw from the very bottom of the kettle?
I don’t see one at NB. Or Williams. More Beer has one, but says it’s for a keggle conversion.
I made my pickup tube out of copper tubing and used the weldless bulkhead that NB sells. You’ll need a 1/2" MPT to compression fitting connector to connect the pipe.
How thick is the wall of your kettle? I would love to add a valve to my kettle but am a bit nervous about drilling the hole because the wall seems so thin. It appears to be 1mm or less thick and I’m not sure I could get a seal.
It’s probably just my paranoia about drilling a hole in a $100+ piece of equipment.
You can get everything you need from them. Bulk head kit, and add a SS ball-valve for $11 (only $5 more than their brass valve) Then the pickup tube will just screw into the coupling on the inside of the kettle.
The sidewalls aren’t very thick on my pot. It shouldn’t matter, really. The weldless fitting seals on the inside and you can crank the nut as tight as you need to regardless of how thick the walls are.
Yeah I know what you mean. I had a tiny leak in mine when I first drilled it. I just put on more teflon tape and rubber gaskets on both sides of the kettle and it stopped it.
To mention BargainFittings again (I’m not getting paid! just recently bought a bunch of stuff from them).
They have another bulkhead kit that is designed a little differently and is meant to seal up slightly over-sized drill holes. It has a washer soldered onto the nipple and uses a flat gasket on the outside. The standard bulkhead kit uses round gaskets with a locknut.
I recently ordered 4 of these for my system, and none of them have leaked.
It’s $5 more than the standard kind, but that’s worth it for peace of mind.
You could get this bulk head + SS Ball valve + copper pickup tube for $41…I’m not sure what you’re looking to spend, but that’s not a bad deal. No more sanitizing the siphon…just hook up a hose to the valve and open it.
Used the weldless KettleValve™ Ball Valve (1/2"). It’s about 3" up from the bottom because of fears that any lower the heat would melt the red rubber o-ring on the outside. Initially got bi-metallic corrosion on the inside so added a gasket to eliminate contact.
Drilling is easy. Just be methodical. And you probably could go lower than 3".
