Boss TRV's

[chip]

Hi,

I have a whistling radiator. If I change the TRV is it likely to stop? Also am I right in that they can be changed insitu and all you have to do is turn it off (to 0) and unscrew and to reassemble turn to 5 and reconnect?

Thank you.

Your TRV may be on the return pipe instead of the flow in which case you will have to swop the valves around.
If you believe the TRV is faulty then change it for a dual flow one.
Either way you will have to drain down

Thanks Bahco, I'll take a look and see what's doing.
