I generally sparge until my BK is full. Unless it's a small beer and the gravity falls below 1.007-8 when lautering.

Use the 1/2" Circle Flow Kit from Loc Line. Works awesome as a sparge assembly and is fully adjustable, easy to clean, etc! My rotating sparge arm clogged up doing HERMS through it - with the Loc Line all the goooey pre-wort flows just fine.

^ That's what I use. It's connected to the mash tun lid and is fed from another 5-gallon beverage cooler HLT. Nice and easy with great results.

Thanks for the help.

put a hose clamp on the end to close it, cut holes spread over the last foot, coil that in a circle halfway between the middle and the walls, with the holes facing up.

keeping it off the edge and closing the end are important to avoid channeling.

These are great ! Thanks for the video and link, It appears in the video that the sparge is missing the outer area of the mash, Is this any problem. I normally keep my sparge water about 1-2 iches above the grain bed for less channeling, You system looks great, Will give it a try. I like the way it can be taken apart and cleaned.

If you Continuous Sparge and keep 1-2 inches above the grain bed then it will not matter. The Loc Line will simplly apply that water without digging into the grain bed. YOu can also twist the Loc Line discharges so every other one points outward and you will get almost out to the edge (and more gently apply the water).

Basically, it isn't necessary to match in and out flow as long as your run off time is the same (about an hour) and the water isn't actually mixing in with the mash, but staying above it until gravity drains it through. Now, this does assume you have an insulated MLT so you don't lose heat.
I've been batch sparging but thinking about trying continuous sparging. Your technique sounds interesting, but one thing worries me. What happens if you get a stuck mash? If you only have an inch or two above the grain, you can stir, vorlauf again, and start over, but if this happens with all the sparge water in the tun and you have to stir to clear it, then it seems you're forced into doing a batch, or maybe it could even be considered a no-sparge, with corresponding loss of efficiency, causing you to undershoot your gravity.
