Hi all, strange day today, i conditioned my grains set my rollers at 1.0ml no more problem with bits of grain or cloudy wort, hit all my targets, "BUT" throughout the mash i had a substantial amount of foam on top, my grain bill was 3.4k MO, 210gm crystal and 100gm of black malt. any other GF users had this happen.?
I've had extensive foam in my GF when I haven't seated the recirc pipe properly, and it's drawing through air. This generally happens if I haven't held the recirc pipe vertically when screwing it in place.

Hopefully now got it sorted, i was not tightening the recirc pipe tight enough as it was unscrewing the ball valve when disconnecting.

Wow, funny you say that. Next brew after I posted. I had the same foaming problem. I do remember the ball valve and the safety valve coming apart a bit. It was not leaking and hot so I left it like that till the end of the mash. This will be my fist thing to check if it happens again.
