Ok... Here is what I have for my system.
I have a cooler with a manifold for my mash tun. With a float switch and a pump, I am able to fly sparge.
I have an aluminum frying pot for my hot water needs, although this is on its last leg. It has a ball valve and the seal leaks... a lot. Probably easiest to replace it. It has its own propane burner.
The Boil Kettle is a converted keg. I have a pickup tube with a stainless steel braid. It has its own propane burner.
I have a pump attached to a small square metal table with a CFC chiller mounted below it.
The Mash Tun and the BK both sit on the cinder blocks.
What went wrong this last time? Well... the aforementioned seal on the HLT went for shit, so during the mash, I had to go to True Value to try to replace the seal (along with the threaded nipple). Problem is, the seal they gave me started burning. It worked for this last brew, but needs to be replaced. Hell, the whole pot should probably be replaced as it barely meets my needs on the sparge water. I don't remember coming up short back in California, but it just seems like my amounts are off.
I had some problems engaging the pump coming out of the BK. Fecked around for about 7 minutes trying to get it going, only to realize "user error" at one point I had flipped the ball valve coming out back closed. I blame that one squarely on me. But it did seem like it was hard to get it going.
Finally, there was a lot left in the BK well above the pickup tube. Maybe I just need to go in and tighten it up a bit. It's maybe just losing suction. But based on my measuring stick, I had around 5.5 gallons (heated) heated in the BK, but only filled the fermenter to 4.5. I carefully poured the contents of the BK into another stainless pot, got the burner going and brought it to a boil for a few minutes, and then used an IC to cool it down and poured it in the fermenter. It brought me to a nice 5.5 gallons in the fermenter.
It was just a bad day I guess. And it was hot and humid out. Nothing catastrophic, but a bunch of tiny shit that made me not like the hobby for a minute.
I guess I need to replace the HLT with something maybe a bit bigger and have a valve installed that will work with my hoses going to the pump (yes... I use it to fill the Mash Tun, Sparge and clean the CFC). I also need to tighten up the pickup tube on the BK, likely replacing the teflon tape in the process.
So... it's not all bad I suppose. But I still wouldn't mind having the fully automated Picobrew. Based on my setup, I can't brew in winter without making significant changes to the system.
If ya'll have any thoughts, I'm open to hearing them.
