Angry,I would remove the white pressure relief valve that is installed right next to the wall. Your water heater should have a pressure relief valve on it so that one in your photo is not really needed. By removing that pressure relief valve, you can install a union coupler in its place. ...snip
In another thread, the poster said that his plumber told him that it's code in his area to install a pressure relief valve after the pressure regulator in addition to the pressure relief valve on top on the water heater. If your area has the same code, then don't remove the pressure relief valve shown in your photo, or do replace it with a new one.
It's not code in my area to have a pressure relief valve after the pressure regulator in addition to the one on top of the water heater.
