Default 10 Gallon Megapot - dip tube needed

Hey guys,

I'm almost done buying all my equipment and ready to brew, when I looked at my megapot this morning and realized the bulkhead was about an inch (going from memory here) above the bottom of the kettle. I did some research and found that this is pretty common and that I should probably install some kind of dip tube / pickup tube.

The threaded coupling in my megapot bulkhead is 1/2" so I was looking at ordering either of these 2 from bargainfittings.com.

http://www.bargainfittings.com/index.php?route=product/product&product_id=120

http://www.bargainfittings.com/index.php?route=product/product&product_id=157

I kind of prefer the dip tube kit, since I think I can position it closer/further away from the bottom as needed, and keep it close to the sides away from the center.

What do you guys think? Are there better options?

Julian

Looks like you want to go Stainless. You can pick up the parts at HD for about 8 bucks to make your own if you didn't care about SS.

The thing with that top one is that you might not be able to thread it on if your bulkhead isn't high enough. If SS, go with #2. If you don't care, find an angled stub out at HD. A compression fitting and a hack saw and your done.

Yeah, I was planning on going SS.

I'm not sure what the clearance is, I'm gonna have to measure when I get home.

Some guy has a really nice setup with his Megapot that I found on NB.

I've emailed him and hope he will respond as to parts used, but anyone here possiby know?

Looks like it could be a:
1/2" NPT street 90 elbow http://www.bargainfittings.com/index.php?route=product/product&path=36_39&product_id=120
1/2" NPT X 1/2" tube compression adapter (http://www.bargainfittings.com/index.php?route=product/product&path=36_39&product_id=103)
1/2" outer diameter stainless steel tubing (http://www.bargainfittings.com/index.php?route=product/product&keyword=tubing&category_id=39&product_id=1 64)

Thats what it looks like to me. You could also get a 90* SS elbow and use it to replace the coupler on the inside of you kettle, it should sit off of the bottom enough to flow and will pull more liquid than the coupler. If you do go that route, remember to clean thoroughly, as the threads could build up some nasty Sh!t

Thanks ZWood...you know, I think the best bet is the pre-made SS side pickup tube I linked to earlier. I'm going to order that. It's 1/2", no threads to get gunked up (that would be a pain to clean upside down without removing completely). I think that should do it. Plus, it's about the same price as all the parts above, but already in one package.

I have a 15 gallon megapot and was looking at the same thing. So far I have just been tilting the kettle to get the last gallon or two out.

I was thinking you could just take a street elbow and grind out the threads if you were worried about gunk. That setup looks sweet but there's like $20 worth of hardware there when I think you could do it with only one piece and some teflon.

So I got the pickup tube and am questioning it's usefulness and if I installed it correctly.

I tested with water, and I need to tip the kettle anyway to get the remainder of liquid. Doing it this way I had about 12oz of water left over after the valve stopped draining (see pic below). Is it normal to have to tip the kettle? I thought having the pickup tube should eliminate the need. Perhaps my expectations were wrong...

Also, does the installation look right to you guys? I feel like the pickup afforded me maybe 1/8", 2/8" at the most, of added clearance but again, tipping is still necessary.

Thoughts?

It's only going to continue sucking water out of there as long as there's a siphon. So, when it gets to the top of the dip tube, the siphon will break and it will stop working. If you really want to pick up every last drop in there, you can use a *shorter* dip tube turned 90 degrees and going right down to just above the surface of the pot. However in that position you can easily get clogs from hops and hot/cold break so I'd only do that in an HLT or perhaps if you have a really good setup for filtering out that stuff before it gets to the dip tube.

Why would have having an elbow pointing straight down clog it vs the dip tube positioned just slightly more off to the side? If you whirpool to collect all the break material in the center before draining, wouldn't both ways be just as effective or susceptible to clogging?

The way that he has it set up has a larger gap between the dip tube and the wall of the kettle. Also with it being on the side it is elevated a bit above the trub/hops. If you go straight down to the bottom and only leave 1/8" clearance to maximize the siphon there is a much greater chance of hops clogging that 1/8" gap.
