Klarstein Mundschenk

I turn off the pump before closing the throttle to ensure no liquid is left in the neck of the pipe (otherwise it dribbles out and down the tube!).

I'm not sure it matters which way it's turned on... though I might try making sure it's open next time, just so that it gets a clear run-up to help shift any debris.

(edited as I had the top line back to front!)

I put a hose nozzle into the top of the pipe and turn on full.

Had a breakthrough on my recent Mundschenk brew. At the end of mash I used a tube to direct the wort directly down the overflow pipe for a few seconds in an attempt to shake up any grains that had made it through the grain basket and recirc them back up to the top of the grain bed. It worked! When I dipped a sieve in the pre-boil it was clear of grain and usually it takes 4-5 dips of the sieve to fish the grains out!

The tube was actually quite long and I pushed it all the way down until it touched the element. The tube has a fitting to attach it to the pump pipe outlet camlock.

Grain in kettle, either suckback when the pump turns off and siphons down, or overflow down the overflow pipe or through the side holes for the lifting bar.
Try a scrunched up tea strainer mesh on the top of the overflow to stop it getting down that way and watch your levels for the side holes.

Better still get rid of the overflow pipe altogether, it is far better for all the wort to go through the grain bed, not down the pipe. Block the hole with a plug and nut. I do full-volume mash and never had anything get into the pump.

Agreed I want my recirculated mash liquor to go through the grain bed rather than any other way.
I've blocked off the overflow pipe a while ago as well.
