LOL... sweet! It ain't pretty but it works! The ones I keep using don't really fit my pot at all which is the biggest reason I want to replace it but that looks perfect for a rectangular cooler!

A lot of folks just use silicone tubing.....it floats and as long as you have ~1/2" fluid on the surface of the mash, you should be good to go....

A rainbird sprinkler works well.

Just use a cheap showerhead and fitting to suspend it above the grainbed. With a little adjustment you can reach all corners of your MLT and maintain a nice uniform flow.

It's not worth the effort. See post #13. That's how the Sabco Brew Magic does it. You are flysparging so you need an inch or two above the grainbed, why would a manifold help in that case?

I think you misunderstood me, I meant just use a showerhead to distribute the water INSTEAD of a manifold or other huge honking contraption with lots of tiny sparge hole or slits. The showerhead will easily spray to all corners of the MLT.

I think you misunderstood SawDustGuy

The current line of thinking is that if you have an inch of water covering the grain, there is no need to distribute the sparge water across the MLT...just add the sparge water to the surface and it will distribute it's self. So a hose is all you need, no sparge head, sprinkler, or whirly thingamabob (I have most of those, but just use a hose now)

I see. Well I've been just using a 1 gal pitcher with an upside down plate to eliminate channeling. Now that I know it's that easy I may as well buy a march pump and upgrade my MLT to a RIMS system. Here I have been stressing about how best to distribute the RIMS liquid when I can just let it flow right back on top with enough water-level above the grainbed.

If you are dumping it in from a pitcher, the plate is probably a good idea to avoid disturbing the grain. But other wise, just "gently" add the water to the top.

The hose also eliminates problems of clogging up a sparge device with small grain particles when you recirculate.
