I'm planning on taking the step from extract brewing to all grain with BIAB. My plan is to buy a induction hob, 15 gal kettle and a March pump.
Will i need some kind of spacer to keep the bag out of the spigot when i turn on the pump?
Two ideas for you, with the caveat that I have no direct experience with pumps + BIAB, I'm just spitballing here.
A false bottom will keep your bag off the kettle floor and away from the outlet. I couldn't easily see if MoreBeer makes a false bottom to fit that particular kettle, but there's probably a generic product that will fit reasonably well.
A screen on the kettle outlet will prevent the bag from being sucked directly in. I use a tube screen on my kettle to keep loose hops out when I drain the wort, the same should work just as well for maintaining even liquid flow through the bag to the outlet.
