How do I remove this?

[Lumatic]

I need to remove the flange in the photo so I can remove the plywood cover and remove the black water tank. How do I do this? I see 2 opposite notches in the black flange. Is the flange threaded? Do I back it out? Pry it out? Do I need a special tool to engage the notches? If I bust it are replacements available?
Thanks

Flange is threaded . I used two large flat blade screwdrivers and formed an "x" and spun it out. Others have made a tool, a flat bar with two properly spaced pins . Good luck.

Put a little food grade silicone on edges when replacing.. helps seal, too.

Is there something about the purity of precious bodily fluids I don't know?

If you are talking about sealant, won't that make it impossible to remove later?
Could you mean silicone grease?

Jacob D, food grade silicone is the consistency of petroleum jelly.
I used it all the time when I repaired water softeners. It lubricates
the rubber parts and keeps them soft, and protects them from liquids
that might start to decompose them.

Half a century ago, I was a systems engineer in a coal fired power plant that used pneumatic control systems. Silicone grease, similar to that which you describe as "food grade", was used to lubricate tiny ball bearings. We also used silicone sealant which set to a pliable gasket to seal some instrument enclosures against harsh environments. These were "state of the art" substances at that time. The term "food grade" applied to both types of silicone if it did not contain chemicals that could harm a person if ingested. Forgive me if time and progress has changed the technology in a way I am no longer familiar with.
