Are you running the tap water slow? The wort coming out slow? Or both
 
That's pretty much how I ran it, re circ until wort was around 50 deg. Wort into fermenter was still 28-30deg. Used a heap of water tho. Might make a ice slurry in a esky and run the water feed thru that first
 
anyone else had issues with leaks on the pump output? Had to remove those and stick a tie on a bit tighter.

are they using zip ties instead of clamps ?

is it so no one tightens up a clamp and busts a pump nipple ?
 
Last few brews we've had some issues with a leak in our chiller around the hexagonal nut adjacent to the part where the red hose is attached. (and the leaks only happen once the chiller has a tap water running through it).

Yesterday we took apart the chiller and found the (white) o-ring for that thread/connect was in very bad shape (it was warped, with hardened bits, and also with fraying bits coming off it).

Without a replacement o-ring we had no option but to put it back together and hope we hadn't made the problem even worse. Once we started using the chiller, the leak was just the same as it had been in the past. We used a towel to stop the leaking water making its way over the edge of the lid and risk it getting back into the wort.

(We've contacted iMake about this, so I'm hoping they'll send a replacement o-ring and that'll fix that problem).


Also, yesterday we had another, separate issue. We started pumping the wort, via the chiller, into a fermenter. About 8L into the transfer the blue hose popped off the chiller and water went everywhere (thankfully mostly over the brewers and the floor. We convinced ourselved that none went back into the wort, but in reality it surely must have). We re-attached the blue hose, made sure the clamp was nice and tight, and continued the transfer with hopefully no serious harm done to the beer.

So check your hose clamps!

I have put a hose clamp on now, however you can't put the pump cover back on with a clamp or even a bigger cable tie as it needs a bit of clearance to get up under the black plastic to close.

better than leaking wort of all over the place tho! This was just testing it out on saturday, i have not made a beer yet.
 
Would a small spring clamp like what you find on radiator overflow hoses work?
 
My recirc pipe bracket tacks have let go :(. Warranty issues all the way over here in Perth might be problematic.

Yep, assembled mine today and ran a cleaning cycle, noticed a steady drip out of the bottom of the pump cover. Took it apart to see it was coming from exactly where you're highlighting.

I put another cable tie above the pump cover, near the top of the pump nipple, this stopped it. Have reported to GF to see what they'll say.

Couple of questions after putting mine together and running a cleaning cycle (and reading 11 pages of this thread!):

1. The pump filter that pushes into the pump inlet seems a bit loose...I've fiddled around with it but I reckon it'll get knocked out really easily during the boil. Anyone having the same issue?
2. Once I'm through the supplied cleaning liquid, I'll start using home-made PBW (70% perc/30% met). Just curious how much PBW people are using in the 7.5 litres of cleaning water? Tablespoon or so?
3. Is anyone putting the mash pipe back into the boiler during the cleaning cycle, or just cleaning it separately?

I've had no probs with this

I just use Aldi napisan and make sure I rinse well

I leave the pipe on and direct it to the walls (of the gf not the kitchen) and clean them

Thanks, but I meant the inner basket rather than the recirc pipe.
 
Cheers. Also, the bottom plate for the inner basket doesn't have any kind of seal around it. And it's a bit concave...any issues with grain leaking underneath it and into the pump during the mash recirculation?
 
I haven't had any that have bothered me. Perhaps if there is any they drop out after whirlpool or ferment
 
Can fellow GF owners tell me how flat their bottom filter plate is? As I mentioned, mine's a bit curved and I'm not sure if that's meant to be, or if it should be flat?
