It's called vorlauf, and yes I usually take the first stuff that comes out of my mash tun and pour it carefully back into the top of the cooler, until the runnings are relatively clear of gunk. It doesn't need to be tottaly clear however, the pic above is from the end of a batch sparge, i.e. the very last runnings.

ok, Thanks for using the Vorluaf word too! I've not been able to find a definition brew related but have seen it a lot when referring to sparging.
Vorlauf refers to exactly which process? The recirculating the first running, or the recirculating until it runs clear of floaties?

Vorlauf is the same for any process. It is what emerges from your mash tun when you add the sparge water and eventually becomes wort.

By clear, we're not speaking of it being clear like glass. We're speaking of it being clear of particulate matter.

Uhm, this may seem painfully obvious, but your mash tun never holds your entire boil volume. The difference is made up with the sparge water.

No need to upgrade anything. But you really should just go up to a ten gallon cooler and stop messing around!
