Hi
Just installed a vertical rad from plumbworld with a bi directional TRV which was installed on the return. The Trv seems to not do much so I queried it with plumbworld. They stated the Trv must be on the inlet side regardless of it being bidirectional. Is this correct? What was the point of them selling me a bidirectional Trv.
