Hey y'all we have drained our 20k in ground concrete pool to do some repairs and there are several places where I see this cap. I'm assuming it's a Hydrostatic Valve and if so, I would like to remove the valve so the pool doesn't float while we do patching and cleaning. Can someone confirm and if so is there a tool that I can get to remove it? Or is it simply turning clockwise? Thanks in Advance!
Hydrostatic Valve?

That doesn’t look like it’s removable. Can you clean it out a bit and look closer? Removing it by turning would be “counter-clockwise” (if it’s removable).
Do you have a main drain? Check that for the valve.

It is a drain plug and is used when a pool is drained to open up a path to relieve any pressure from water underground so it does not pop the pool out of the ground.

There does not appear to be a removal tool for it.
To remove a hydrostatic plug, chisel the plaster out from inside of the plug, so that you can get a pair of straight pliers onto the center ridge. Twist counterclockwise and the hydrostat plug will thread out.
