OK, so as soon as I would have seen bubbles in the blowoff, I should see the pressure gauge move. Makes sense. Do you have the Brewhemoth pressurizer?

Well, I've fermented two different batches now in my Brewhemoth (a pale ale in August and a hefeweizen three weeks ago), and I've gotten horrible off flavors both times. In between those batches, I brewed a pilsner and an Oktoberfest in glass carboys that were flawless. My Brewhemoth cleaning/sanitizing regiment is as follows:

1.) Use a CIP (1.3 HP pump circulating 5 gallons of PBW water for 1/2 hour) through a SS spray ball
2.) Use a carboy brush to scrub the remaining krausen ring
3.) Rinse with 5 gallons water through the spray ball
4.) Add 10 gallons water, swish around, and dump
5.) Add 5 gallons Star San, swish around, and dump.

The pale ale infection was a strong solventy, paint thinner taste while the hefeweizen is a slightly sour taste. Does anyone have any suggestions?

"Strong Solventy" suggests higher alcohol, perhaps from higher temps or over-oxygenation while sour definitely suggests an infection of some sort. If you're convinced both are due to an infection then I'd probably fill the conical with PBW/Oxiclean overnight, then soak all the parts in that same solution overnight to make sure things are clean. Then maybe a boiling water rinse/soak or even a boiling water recirc for a bit. Then sanitize as normal and then fill with wort. Just my $.02.

Yeah, I initially thought the pale ale's problem was fermentation temperature or an under pitch until I took it to my brew club meeting and the consensus was unanimous that it was a sanitation issue.

I'll do the PBW soak next time I brew, for sure. what kind of pump are you using that you're able to recirculate boiling water? My dirty water pump specs only goes up to 90 degrees.

I don't have a conical but if I did I'd use my LG or my Chugger to recirc the boiling water. Just put it in the loop and let it run, it can't hurt right?

Have a heatstick or bucket heater? Throw that in the conical as well, it'll keep the temp up for a longer period of time.

Another idea is to fill it to the brim with a heavy bleach mix and let it soak. That should kill any nastiness. Do the same for all fittings and valves, especially butterfly valves in the open possition. Then a really good rinse and back to normal procedures. Also, make sure to thourghly clean any other hardware and rubbing used with it that was not used with your car boys.

Just an opinion.

I guess I'll do a PBW soack, a bleach soak, and rinse thoroughly. I hope this won't become the routine for cleaning this thing.

Pick up some Five Star Sani Clean while you are at it, that product is low foam and you should use it CIP.
