Use a loop of SS mesh here, flex plumbing hookup with the inner rubber hose removed, connected to a T on the outlet. Stupid (me) crushed (put a kink in) Mk 1 with his mash paddle. Now using MK 2, my mash paddle now is a length of dowell I mix around and inside the loop of SS mesh. Tried a single length crimped at one end and connected to the outlet at the other, if I turned the tap on full at first the mesh tube collapsed and lauter stoped, so went back to loop, no probs since.
