Of the 27 lbs of grains, only 1 lb of it was flaked barley. The bag of rice hulls was also one pound, I believe. The volume was actually greater, for the same weight. I added them to the initial mash, but they obviously got all stirred in with the grains.

Whelp... I've struggling with stuck sparges recently. My previous grain bill called for some flaked barley, and it got stuck pretty bad. As I had a couple of mashes without the flaked barley that didn't get stuck, I assume that is the culprit. So with my mash this weekend, I used rice hulls...

Similar... I've pumped uphill 4-6 feet on occasions without issue.

I'd definitely recommend the second unit...

OK, cool... thanks. I haven't seen them at my brew supply store, but haven't specifically looked either... I'll have to ask them.

No... guess that's the next step...

Well, I seem to be having a bit of a stuck sparge with my ice cube mash tun. I've done 3 batches with it, and I've had issues twice... and I believe both times it was with a recipe that had some flaked wheat in it... has anybody else found this to be a problematic ingredient? The other...

I Starsan at the beginning and end of each brew.

Stereo pumps, AND cookies.. cool!

So you keep saying. And the hum is a factor for you. And you don't like boxes because losing the prime and or springing a leak is "scary". Quite frankly a DC motor of this (im)precision isn't really gonna notice the difference. All motors are going to have a stall point at the low end that's...

Not a fan of eBay for the most part, so I bought here: https://www.amazon.com/gp/product/B00DWORE6E/ref=oh_aui_search_detailpage?ie=UTF8&psc=1 -sc

Probably. The pump I have is rated to pull ~800mA @ 24VDC, so that 1A should be sufficient... although it never hurts to have a bit more headroom on the supply side... especially with the cheaper supplies that may be rated "optimistically".

I found a 24V 2.3A power supply (similar to a laptop supply) in a junk cabinet at work. I also used a barrel connector in the pump enclosure.

Ooh.. that rubber baseboard gasket is perfect. I may steal that. Nicely done! -sc

Cool! It looks good and I like those disconnects!

I'd actually recommend a PWM motor controller rather than a simple potentiometer... there's some detail on that earlier in this thread...

Ah.. good to know. Fortunately that made integration relatively easy... Thanks.

Well, it's an awfully big thread... and we are ostensibly drinking beer. Thanks! :mug:

Actually earlier in this thread ;) I was asked about it and gave a few replies: Starting around HERE at post #1240

Aren't they? My FPT quick disconnects screwed right on:
