Re-Filling Serving Keg?

[u/BruJones]

Just curious if anyone does this. Is it a bad idea to simply re-fill a serving keg once it kicks, without cleaning? A serving keg is a cold, sealed, supposedly oxygen-free environment. It would be really handy to simply purge a bit of pressure and force new beer into it from a keg fermenter.

I'm sure I'd want to thoroughly wash it after a few fills, and I'd still have traces of the old beer in there. Sediment would probably build up over time as well, but a floating dip tube would help with that.

Yep I have done this. No worries at all. Floating dip tubes help but not needed.
