Lately I've been in an improve the brewery mode.... If it ain't broke, make it better.
So I was soaking a BB in oxyclean last night and was thinking, "man that is a lot of wasted water. I remember seeing the BYO article on how to make one out of copper and it looked okay, just a bit wide at the bottom and with all of those fittings I'd be afraid I would scratch something.
Here is the build list.
$6.77 - 1/2" type M copper pipe @ 5'
$0.48 - 1/2" pipe cap
$1.57 - #8 hose clamp pack of 2
$2.35 - 1/2" Female NPT adapter
$7.63 - 1/2" Sweat Ball Valve
$4.55 - 5' of 1/2" ID braided vinyl tubing
~$2.00 - 1/2" MPT to 1/2" Hose Barb (Had one on hand)
$3.87 - Portable Dishwasher sink adapter
$7.73 - Mister Landscaper Large Circle Spinner (MLM-15) Pack of 10
$36.95 - Total. You could do better if you buy the pipe by the foot and find smaller packages of the mister landscaper. You could also forgo the ball valve and use the sink valve.
Cut 1 24" piece of pipe and one 6" piece.
Drill a 5/32 hole in the middle of the pipe cap.
Sweat the 1/2" FPT adapter to one end of the 6" pipe and the valve to the other end.
Sweat the other end of the valve to the 24" pipe and sweat the cap to the end of the 24"
I took a sending drum to the lip of the cap so it was nice and smooth. Didn't want to scratch up the neck of the BB.
Take one of the mister landscaper bits and screw it in to the hole in the cap. It wont screw right in and will require a fair bit of force while turning, but it will go. Maybe seating it with some JB weld or other epoxy would be a good idea.
Thread in the 1/2" hose barb at the other end and attach the hose with a hose clamp.
Push the portable dish washer faucet adapter on the other end of the hose and secure it with a clamp.
Screw it in to the sink turn the hot water on. Shove it in a better bottle and let her rip.
I don't have a dirty carboy to test it on so I don't know how effective it is. This is the first time I have looked forward to cleaning one...
