Some time ago while I'll was still brewing outdoors, I had an event that I still don't quite understand how it happened and spooks me every time I brew, even more so that I've moved indoors. My setup is as follows:
I was recirculating near the end of the boil, roughly 45min into a 60min boil. Pump was primed and open, bottom port valve of Robobrew was open, and wort was moving. I might've made a minor adjustment to the outflow control on the pump and suddenly the hose between the Robobrew and pump started to swell up like a balloon. I closed the Robobrew bottom port valve, scaled the flow valve to zero on the pump, and disconnected (thank goodness for QDs!) the hose before it burst.
Since then (15-20 brews later) I've not had any issues but I still don't fully understand what happened, other than somehow the liquid must have super heated within that first hose but I still don't understand how. Can someone help understand my process and what I might have done wrong? I'd like to not attempt it again and be more mindful, especially with hot wort and now brewing indoors!!
- Robobrew
- Bottom port to Blichman pump
- Pump outlet to inlet of Chiller Plate
- Chiller Plate Outlet to Homebrew Hardware Recirc arm back into Robobrew
- All hoses are brew-rated silicone
