Mash tun deadspace in a cooler with dome fasle bottom
 
So I have been using the stainless steel braided hose in my mash tun, which is a 10gallon Rubbermaid cooler, with great success. My deadspace was less then .25gallons and it filtered the mash just fine.

Now I got a great deal on a domed false bottom from Kegworks, $6.04 which included shipping!
It's only a .5" high and doing some math it would seem that the deadspace should only be .27gallons, yet I just filled it up and let it drained and it left .5gallon in the cooler.

Does this seem right to other that have used the domed false bottom in a cooler?

Would soldering a small length of copper pipe to the hole on the bottom so it reaches down to the bottom of the cooler sound like a good idea so it will suck up as much wort as possible?

You bet. Just make sure to leave enough space so you don't restrict the flow.

Did you just open the ball valve on your tun and let it drain, or did you hook up a few feet of tubing to the ball valve for the siphon effect?

Cheers!

I have a right angle fitting on my FB which goes through the hole in the middle - it's 3/8 barb on the top side and 1/2 MIP on the bottom. I removed the nut on the bottom side and replaced it with a sawed off piece of 1/2 SS coupling. I sawed the coupling in two pieces, about 60%/40%, but can't remember which piece I used. The coupling comes down to within about 1/8 inch of the bottom of the cooler. I used teflon tape on the right angle MIP threads for a good seal. And like day_trippr said, you need a piece of tubing on the output to keep the siphon going - I also like to keep the output end of that tubing submerged when I get down close to the end just to make sure no air gets in from the outside to break the siphon.

Classic fixing something that aint broke example. :mug::mug:

Please report back on the performance of the FB versus the braid as this will be a true comparison rather than the usual hearsay..."mine is better" commentary....thanks and cheers!

Thanks for the help guys.
I had a brain fart and totally forgot about the tubing to keep the siphon going.
Even with that though I feel as if the deadspace would still be more then my liking, so I'm definitely going to try soldering on a piece of copper pipe to the bottom as a little dip tube to get those last few liters of wort out.
So I guess I'll still be using my stainless steel braid for tomorrow's brew session though, and yes it ain't broke, but how could I pass up a pricing screw up on Amazon for a false bottom. They accidentally listed it for 2cents and $6.02 for shipping, so the whole thing only cost me $6.04!

I'll report back once I get the false bottom up and running and I compare my results against the SS braid.

Oh yea, I understand how that works, also as the price goes down I buy in greater quantity irregardless of need! So how many hundred did you buy?

I put in for 10 and they would only ship me 1 hahaha
They changed the price in a matter of a few minutes, but honored 1 order for all who ordered at the low price.
Check out the twitter account @homebrewfinds, they are always finding great deals like this. (Also has a website, www.homebrewfinds.com)

I agree with this. Just plan on an extra quart of equipment losses and you're all set! If you are hell bent on getting that quart back and do the solder thing...make sure you use a lead free solder and flux!

LOL...I read it totally differently, I thought he was saying that an extra quart of losses isn't really a problem rather then braid to FB upgrade is fixing what's not broke. At any rate, I still feel the same as my above post. I wouldn't do anything other then adjust my recipe. A quart of beer isn't a big loss.
