Yah but it might be rusted at the joint or not easily accessible and trying to open it might not be a good idea in a rented place. The kitchen sink in my apartment has copper fitting so I didn't dare to touch that. The sink in the toilet was flexible and yet I had tough time to open the threaded fitting (probably I am the one who opened the thread since it was fitted, maybe a decade ago )
