Old DE filter- how to vacuume to waste?

[Rangeball]

I'd disconnect my pump supply line from the filter and just shoot the water straight out of the pump.

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.
