New radiator valve on 1/2 inch iron inlet pipe

Anonymous user 23/02/2024 - 3.12 PM

I am on a communal heating system in a block of flats. I want to replace valves on old 1930's radiators. I bought new valves that have 1/2 inch thread to radiator but 15mm inlet pipe. However, as my existing inlet pipe is 1/2 inch iron, I was advised by a plumber that it is not possible to install my new valves. The only valves he could find that were suitable for 1/2 inch inlet connection are the Drayton TRV4 valves. Question (A): I am not sure if my plumber was being lazy when he said he could not connect the valves with 15mm inlet to a 1/2" iron inlet pipe. I would like to know if a plumber with more expertise and problem solving skill should be able to do this? Question (B): Where can I source better looking valves than the Drayton TRV4s that would be suitable for connection to a 1/2 inch iron inlet pipe?
