i put a 1/2 copper cap filled to the rim with silver bearing solder in the end of my stainless braid with a stainless hose clamp to prevent the floating action; and hopefully resolve my stuck mashes i have been falling victim to.

That is a long braided section. I used to have the issue with the braid comming up into the grains. I cut it off and it is only about 8 inches. I have gotten the same efficiency with both the long braid and the short. 75-80%. Luck!

Another thought...are you sure the braid is not being crushed under the weight of the grain bed? Have you added any kind of structural integrity to the inside of the braid? I (and a lot of others) have used a section of copper wire. You wrap it around a pencil to form it and then insert inside the braid. This adds some rigidity.

The 3:00 minute mark of thsi video shows what I am talking about:


I had a hard time finding any copper wire at the local home improvement stores so I just bought a length of 10-2 electrical wire, split the casing and ripped out the ground wire. This has proven to work exceptionally well for me.

maybe reundant, but put a short hose or line from the spout down to the bottom and then attach the braid so you siphon off the bottom, reducing dead space

I have a short hose (pun intended) and nothing inside of it to keep its shape (double entendre intendred). No problems with floating or efficiency. Think about it. All of that hose doesn't increase the diameter of the outlets at all. I suspect that beyond 6-8 inches you're likely to have rapidly diminshing marginal utility, and an increasing likelihood, certainly, of the hose floating.

I'm Irish so 6 - 8 inches is a world away! :S

I can attest to this as well. My braid is probably 8-10 inches, with a square plug in the end. I've had no issues with the braid floating and have been getting crazy efficiency (87% according to BS). Only issue I've seen approaching is the braid slightly collapsing and/or stretching. Oh well, i guess thats a sign for an upgrade in the future!

I do exactly the same thing...square brass plug in the end like this one:

Unscrew that tee and put a 45 degree elbow, then a hose barb. Hopefully that combo will put the end of the barb very close to the bottom of the cooler. Then slide on a 10" piece of braid and clamp it. Then clamp on a 1/4" NPT pipe plug to the open end.

I was getting high 80's to low 90's % efficiency in a cooler with a braid. You have too much deadspace.

I doubt the braid is the issue. Whether it floats or not doesn't really matter. The wort doesn't travel through the length of the braid like it would with a manifold system. The braid isn't solid at any. The reality is that the wort enters the braid at the point where it connects with your brass "T" fitting. You could actually achieve the same results if you just put a piece of fine mesh screen over the openings of the fitting. If you are having issues, it's likely due to the height of the drain in the cooler itself, or the height of the "T" fitting. Bobby M actually probably has the best suggestion. Replace the "T" with an elbow to lower the drain height. Or at least attach a barb straight to the nipple and attach your braid to that.
