what diameter tubing did you use to fit the drain hole without it leaking? TIA

If you need a valve to go with flow control, you can always do something like this.

I like the simplicity of your system. Papazian would be proud!

Sorry but I don't recall. Basicly the tubing needs to be oversized by 1/16" - 1/8" larger than the cooler bulkkhead so it is a tight fit...slicing the tubing lengthwise at an angle for 3-4 inches and compressing the end will help to squeeze it and pull it through the bulkhead, then trim square.

Nice! This is almost exactly what I do, so I have no dedicated mash tun -- it's simply the family cooler (actually, 4 different ones over time... they all seem to have the same size outlet hole). If your LHBS has those cheap little $3 inline valves, they're worth every penny.

thinking about stealing this idea for the mash tun cooler Santa will be bringing me

it occurred to me that instead of having to buy additional vinyl tubing for draining, would it be possible to just use the tubing that was originally INSIDE the braid?

and do you recall what diameter supply hose you used? I'm figuring a ¾" hose would fit through the spigot hole, however, would ¾" be too wide for the braided part?

Id be worried about the grain crushing the tubing. Check out silibraid silicon

this braided hose is 24", which is the width of the cooler. the vinyl hose separated from the braid would only be used to go through and out the spigot, so only minimal amount would actually be covered in grain.

much less than the 3rd picture in the OP

While I like the idea of reusing the hose from within the braided water heater line, I don't think it will work. The tubing pulled through the bulkhead needs to be slightly larger, say 1/16 to 1/8 larger OD than the bulkhead or spigot dimension in order to seal. That tube will also be a bit short IMHO. A decent hardware store should have what you need at lime 30 cents a foot.

Never had grain crush a braid or a hose FWIW.

through the spigot, hole is ½". is the Coleman 70-quart Extreme at Wally World, and I just measured that today at the store

hole is ¾" with spigot removed

you know? I'll try it, it doesn't work, I can always buy some tubing. it really only needs to last for 1, maybe 2 batches before I swap it out for ball valve.

thanks for the info, guys

(& Hail! To the REDSKINS!)

I am assessing options for converting a rectangular cooler and noticed that people always make a copper or PCPV manifold, or use braided hose. Why does nobody use plastic hose (like that used for syphoning or serving lines) and just make small slits or holes in it?? it seems to me that it would be cheap, easy, and with a long hose you could cover a large area. I'm guessing there is a reason though.. Thanks for any input
