I would try a mash with just the bazooka. No real good reason why, I'm just a braid guy.

I tried using that same false bottom but the mash was too thick above it, almost 2 gallons of dead space. After i took it out i haven't had any problems with the bazooka screen only.

Thanks, I appreciate the response. When I unstuck it I noticed that the grain was also clogging the holes of the FB, maybe the bazooka solo is the way to go then. I'll post an update one way or another after the brew session tomorrow, fingers crossed

I used the false bottom with the dip tube on my last brew. I didn't get a stuck sparge, but I did get some particulate matter in my run off. I used just the bazooka tube when I boiled, and it strained the particles out well (think the whole hops helped clear it too).

I am very interested to find out how your mash turns out with just the bazooka screen. I have considered switching to a copper manifold and ditching the false bottom.. But if you get good efficiency with just the bazooka, I don't see why that wouldn't be the way to go. Are you fly sparging or batch sparging? I've heard that when fly sparging with a bazooka tube that channeling might be an issue, but I think as long as you get good distribution of sparge water over the grain bed it should just work fine.


Cheers!

I went with just the bazooka using nearly 40lb of grain and mashing in kettle with a single batch sparge. It worked fairly well, it stuck with a few gobs of flour on the first vorlauf run but after I cleared that it flowed pretty freely. I had quite a bit of coarse grain at first, perhaps the size of rough ground pepper, but after I did a vorlauf with about 3-4 gallons total (~1 gal each run) it cleared up nicely. I didn't have any tunneling issues but also had a mighty bed of grain to work with and kept my ball valve less than 50% open except to clear that initial clog. I had nearly 2 gallons of trub and hop left over after the boil and the bazooka also kept it rather well filtered. I'll likely continue with this method and scrap the false bottom unless another use surfaces for it

Glad to hear your bazooka screen worked for 40 lb of grain! Wow you must have been making a big batch (or high gravity)!

So I brewed another IPA on Saturday using just the bazooka screen in the mash tun. It worked pretty well! I got ~ 77% efficiency and it didn't get stuck at all. I did, however, notice a BIT of channeling on the grain bed during the fly sparge. There was a "mound" in the middle of the grain bed and it was lower around the perimeter. But I think this may be attributed to the way my sparge manifold distributes the water. Being that I still got good efficiency, I think fly sparging with the bazooka tube works just fine. Eventually I will probably build a copper manifold.. But for now I am gonna stick with the bazooka.


I now use the false bottom during the boil to filter out the hops when transferring to the fermenter.. Worked great for that!

Cheers bro!
