Stuck sparge...what do I do!!!!

Do you have any rice hulls on hand? If so, rinse about a half pound with boiling water in a strainer and throw them in. Stir, and try again.

Sorry to revive an old thread, but THIS works. I just encountered a stopped and then SLOOWWW sparge, followed this method, and I'm back in business.

I learned this from the BN, when you stick it use your spoon or something to cut the grain bed parallel to the valve. This has worked for me twice so far.
