What valve is the flow Hi all
I removed a radiator off the wall and forgot to note what valve was the flow as I'll be replacing with a new radiator with a trv. Without putting back and re connecting how can I tell what pipe is the flow and what pipe is the return because I assume the trv goes on the flow. Btw both plastic caps are missing off the valves. Cheers in advance.
