Hey folks, I'm currently ironing out the kinks of my RIMS, and my latest hitch is bubbles in the system. I've found that if I lay the tube horizontal, but prop up the "in" end (element) slightly, it eliminates bubbles until I start mashing out -- then, when the element kicks on in high gear, I start getting lots of bubbles in the "out" hose. If I futz around and change how high one end is propped up, the bubbles will go away for a few minutes, and then return; then, raising or lower (no rhyme or reason to which, it seems) will temporarily hold them off.
My concern about bubbles is the first time I had them -- when I brewed with the kit the first time -- I scorched the wort something fierce, and had to scrub all the black crud off my element. I'd like to avoid that again! Clearly the bubbles are being created as the element aggressively heats the wort, but is there any solution that comes to mind? Or, is it ACTUALLY an issue at all?
System Notes: Chugger pump, Bobby's "old" RIMS tube (Threaded), 6000w 240v LWD (not uwld) Camco element running at 120v/1500w.
