Ideal length of G30 V3 recirculation tubing

[DominicRL]

Hi folks!

Just cleaning my G30 V3 in advance of my first brew day tomorrow and the silicone tube attaching to the recirculation arm seems extremely long (130cm), is this right, does anyone use theirs at this length or does it need trimming? I am struggling to find anything online so consulting the experts!

All the best,
Dominic

I have a previous version and the recirc tube is only about 30cm long. Yours seems really really long.

Did you attach it yourself? The tubing coming out of the CFC is about that length - I wonder if they got put on wrongly?

I would probably cut it down. It just needs to get onto the top of the grain bed.

This is exactly what confused me! So I’m wondering if it’s because there is no longer a top plate on the V3, ie it sort of floats half way in the wart throughout? But then I don’t imagine it will recirculate as efficiently.

I’ve not attached it yet whilst I figure out this conundrum, it’s still 20cm or so longer than the white/translucent pipe coming from the CFC.

Perhaps it will float on top of the grain bed during use?

Maybe do the first brew with it and see how it behaves. Adjust as necessary after that. It won't do any harm for the first brew, but it's annoying if you cut something down and want to un-cut it!

Wise words! Worst case scenario is there’s more tubing to clean so will take your advice tomorrow - wish me luck! Dominic

Hi I just bought the G30v3, may I ask what was the outcome?

Absolutely, so the full length tube is fine, you just want to check a few times throughout the brew that it’s still coming through at a decent pace - you can try pausing and restarting if not. And as a rule, stir the mash a few times to avoid it sticking!

I got the v3 "upgrade" (replacement malt pipe) which included the extra-long tube length. It's that long because some folk (me included) will use it to pump out via the chiller that is sat on something nearby, not the brewing pot itself.

A bit of fiddling about to rig it up initially, but less than I'd done in replacing the chiller hoses (was a daft idea having the chiller sitting on the brew pot anyway).

I replaced the tubing on the inlet side of my CFC for this reason. Now the CFC can sit on the worktop next to grainfather and I can access the wort for whirlpools/hop additions without having to fight the CFC
