Pocster Posted January 26, 2023 Share Posted January 26, 2023 Assumed all trv’s and radiator valves were born equal . These trv’s seem to have a thread that’s too large for the radiator . Do I need a different trv or some form of adapter maybe ? Link to comment Share on other sites More sharing options...
Pocster Posted January 26, 2023 Author Share Posted January 26, 2023 Looks like I bought M30 Swetup Trv Thermostatic Radiator Valve, 4 Pieces Thermostatic Valves Head Only, Radiator Thermostat Head M30 x 1.5 Try m28 ?? Link to comment Share on other sites More sharing options...
Pocster Posted January 26, 2023 Author Share Posted January 26, 2023 Difficulty finding m28 trv at reasonable price . Don’t want to drain the system and remove the pin …. Hunting for a simple adaptor Link to comment Share on other sites More sharing options...
Pocster Posted January 26, 2023 Author Share Posted January 26, 2023 Is the adaptor indeed another pin that just screws down in the existing pin ? The adaptor costs more than the trv !! Link to comment Share on other sites More sharing options...
Pocster Posted January 26, 2023 Author Share Posted January 26, 2023 Not at site - but looking at my photo . Is that not already an m28 adaptor in there ? . I just unscrew it and I’m back to m30 ??? Link to comment Share on other sites More sharing options...

Pocster Posted February 3, 2023 Author Share Posted February 3, 2023 Right (expletive deleted) it ! order a trv with an Allen key fitting so it can grip the pin fitting rather than trying to screw over it . Rubbish forum - would like a refund . 1 Link to comment Share on other sites More sharing options...

I don't think there's ever a plumber around when you need one, let alone a heating engineer. And they all run a mile when it comes to those pesky trvs Link to comment Share on other sites More sharing options...
Pocster Posted February 9, 2023 Author Share Posted February 9, 2023 Fitted the trv One thing I did notice opening it from 1 to 5 caused the internal mechanism to move a lot . Reality the pin only needs to move a few mm . So it’s unlikely to work properly I.e it’s either fully on or off . But (expletive deleted) it Link to comment Share on other sites More sharing options...
