Here you go

And maybe
http://www.pumpandvalve.com/

It's not cheap stuff. They both sell 'schedule 80 cpvc' which is ridiculous american spec with thick walls for no reason. The first link also sell abs pipe in normal plumbing sizes, which is probably what your chilly bin is moulded out of. Not the same temp resistance as cpvc, but should hold its shape up to 80, perhaps get an off cut of pipe first and try squashing it at 80c? They'll tell you abs is rated to around 60c, but that's only for pressure systems.

Thanks for that GS. Being a PVC I assumed it would be cost effective. Maybe I'll just go with copper instead?

its not expensive in the states, i think that's why its used as mash tun manifolds there. Copper's probably cheaper here.

I used to work for the above, and could probably still get a trade deal, but i used a s/s braided hose!! Works well, although I'd like to reduce wastage in the bottom of the tun. have my eyes on a keg, a domed bottom and a false bottom I think will see me right!

That sounds the goods. Stainless pot/keg would be ideal. I might go the braided hose or bazooka screen route with a copper dip tube to get to the bottom so wastage is kept to a minimum. Do you get good efficiency from the braid hose? Stuck mash at all?

I got a bazooka of Karl at allgrain.co.nz ... it works perfectly, no efficiency problems (i'm consistently at 80%). Hit him up and see what he can do (if you don't feel like making your own) - I think they're around the 20-30 dollar mark?

I used to use a copper manifold, but after it fell apart in the mash - I got the bazooka. Suffice to say, reassembling a manifold in a mash tun at 68 degrees is somewhat painful - but then - I should have soldered it together ... but that would have made cleaning it 'interesting'

I have a 6" bazooka for my kettle but am contemplating not running it on that and just using it for the mash tun. I'll have a play this weekend. Thanks for the input guys.

Robert have you got a photo of your bazooka screen set up? Would be keen to see how it goes together

Ill take a photo later tonight. Its hooked up in a chilly bin at the moment, essentially it just screws into a.socket attached to a stainless nipple that runs through where the drain plug used to be on the chilly bin. It probably sits 2cm off the bottom of the tun - not such a bid deal but there is some dead space at the bottom.

I reused the silicon washer that was in the chilly bin to ensure it was water tight and a nut on a silicon washer on the outside. Ball valve connects to the protruding part of the nipple.

Will attach photos once the monsters are asleep.

Thanks mate. I get the idea. sounds similar to my set up. Maybe i'll run as is with the bazooka screen and have a little wastage at the bottom then make a tube to get the dregs at a later date.

Only used it 3 times so far, efficiency in low 60 s which I'm not over the moon about, previous biab was easy 80. No stuck mashes, touch wood. I think the main lack of efficiency has been due to too much liquid being left behind. I pretty much wrung the biab bag out dry previously...
