Old DE filter- how to vacuume to waste?

[Amir]

I said easy! I will give it a try. I don't know if it can be disconnected easily.

Don't know much about DE filters but how about just removing the grids or whatever they are and putting the valve in Backwash mode? You'll be running the water thru the filter but with no guts, it's effectively bypassed.
