I have decided I ned a pump. It needs to pump boiling wort and be sturdy. Flowrate, maybe 5L/min or so, maybe less can do it, I don't know...? I would like to be able to whirlpool with it eventually.
Craftbrewer has got a couple but with shipping that will probably get pricey:
Quick fix for that pump is a 20oz hammer straight to the shaft while on, one good blow should get it spinning!! If not try constant swearing at it and a quick kick.
Yeah its been playing up lately I think its all the hops stuck in behind the prop or corrosion? but doubt it. Man I couldn't imagine brewing now with out it recirc is the easiest thing in the world now, along with transferring and whirlpooling!!
