From Grianger web site, it says the total before s&h come to 38.73. eh?

But yeah, that's about right. Blichmann AutoSparge sells for an extra $11, but it is a much better design for a MLT than the one from Grainger (great site by the way... finally found 3 way SS ball valves!) The AutoSparge comes with a washer and nut for mounting to your HLT, and a hose with flotation device is already included. The autosparge has also been tested at Purdue University's mass spectrometer for lead content, and is well below limits required for water supply. The float ball looks a ton shinier than grainger's. I like my sparge balls very shinny.

I really like using the autosparge because the little floaty thing keeps the hose in nice spot, and does not move but a few kernels in the light whirlpool of water above the grain bed. I'm pretty sure its more adjustable as well. The ball can be placed +-7 degrees i believe. The teeth on one side of the rod holder are rotated one half tooth to give more adjustment. The risk of hot side aeration is significantly reduced because the wort flows directly back to the top of the wort in the MLT right at wort level.

Here's the boss talking about it. (can you believe we ruined a 20gal pot just for display purposes?)

You guys should have some lexan placed over the opening and have water recirculating though it.

In the name of bling! Make it so!

I realize this thread is about a year old.

I recently got an AutoSparge and had trouble adjusting it. On looking at it more closely, mine does NOT seem to have the teeth rotated by half a tooth.

Has anyone else seen this on theirs?

I took a pic and drew a line in as close to perpendicular as I could and the teeth appear straight across from each other to me. More importantly than the visual is that when I hold the 2 pieces together and then flip it over and hold them together they are still in the same position (which means the teeth aren't rotated).

Float arm teeth



Valve lever teeth. Manual says float arm has the rotated teeth, but I took a picture of the valve piece as well.


Thanks.

I emailed John Blichmann and he said I have an older model (even though I bought it recently, go figure).

I was going to put a washer between the 2 pieces, but I didn't have a washer of suitable size on hand so I fabricated one using a dip-tube o-ring inside a post o-ring. Works great and I know it's food safe.

I'm not limited by the teeth now for positioning!
