How long to drain a MLT cooler
 
I converted a 5 gallon cooler to a MLT using flyguy's instructions and when I used it yesterday it took forever to drain. Couldn't find anything searching through the forums so I was wondering if anyone else has this problem or atleast how long does it usually take them to drain their MLT?

I'm using a SS braided hose with a plastic hose inside (just like in Flyguy's instructions). I mixed in 4.55 quarts of water with 3.25lbs. of grain and barely got 3 cups of wort out of it before it just started to drip out.

So how many holes did you put in the inner hose?

You did test it with water first, right?

When I did mine, I used a fairly large bit and made it look like the barrel of a machine gun...also stretch and compress the braid a bit to open up the SS mesh some, it may be too tight as well....

Mine drains fairly rapidly will the ball valve wide open.

I tried two different braids. They both worked great for their first uses, but did not work as well on subsequent brew days. It was taking 30 min to drain the MLT. I ended up changing to a copper manifold and it drains much faster. I need to vorlaugh a little longer with the manifold, but sparging is much faster overall.

What about the grain bed getting too compacted? Sometimes if you open the valve too fast, or don't have any rice hull with a fine crush the grain bed turns into cement pretty quickly.

The holes were probably spaced out 3/4" to 1" apart from each other, both top and bottom(so every 1/2" there is a hole somewhere). The total length of the hose is about 10". I didn't stretch the braid out though.

I did a water test before using it and ran great.

I was thinking that might have been the issue. I added the water first then added the grain to that. And I did just open the valve up. Didn't have any rice hull in the grain bed. It poured great when I first opened the valve then quickly turned to a trickle.

what was the grain bill? You may have just had a stuck sparge. I never have had a problem with my MLT draining I also have the SS braid but with no hose inside. maybe the braid is wrapped to tight on the hose ?

I'm totally confused here. Why are you adding holes to the inner hose? You should remove the inner hose.

It prevents the braid from collapsing with large grain bills....It's mentioned in Flyguy's thread.

Some people use vinyl, some even use holed copper...I just took out the original hose...put a bunch of holes in it, boiled it to clear the drill scraps, and put it back in...

yeah - just pull the inner hose out. It is not needed. It will work like a charm.
