You can use a fernco coupling and a piece of pipe as a wrench.It looks like you can get a pipe wrench on it.

Thanks, that may work. The strap wrench keeps slipping.

What’s on the other side of the valve body?

You just unscrew that chrome nut. Don’t apply too much pressure a strap wrench would be best.
