    Tapered/Conical shaped pin in TRV?

    Hi all - my first post! I'm trying to help my dad sort out his very hot radiators and find out why it makes no difference to the radiator heat when the TRV setting is reduced i.e. regardless of what the TRVs are set to (i.e. regardless of whether the TRV is at the frost setting, or settings 1...

    Trv pin stiff any ideas what to do

    One of my radiators was stone cold so we've bled the radiator and it was still cold. I've took the trv off and the pin was down, as per some other posts I wiggled the pin and it came up a bit and the radiator started to heat up. Brilliant, however the pin doesn't move freely, it's either up or...

I'm a casual DIYer so this may be a simple question to most.. looking to replace the old head on the photo for a new TRV head.

    Drayton TRV4 problems

    Hi. Having problems with these rad valves. The chrome type fitted to acova column radiators in a renovation project. Ex-plumber here but been out the game for 15 years.

    Connecting 15mm regular TRV to 10mm pex pipe

    Has anyone got any advise on this please. Can I use a compression reducer to connect a 15mm TRV to a 10mm pex pipe? Not sure if the compression would hold onto the pex pipe. Or do I have to go from TRV > copper > pex. Thanks, Mark

    TRV heads, and linking to wall thermostat?

    I have looked at a range of TRV heads costing between £10 and £60 and it seems until you buy them, you don't really know what you are getting for your money. They all use batteries, they all allow multi temperatures to be set depending on time of day and day of week. Some are direct entry only...

    Rad Valves - can you swap the TRV?

    Hi guys, My first post so be gentle! I want to get this rad and the TRV will be sticking out as per this picture: I'll be replacing this with my own TRV which will mean the whole thing sticks out 12-13cm from the wall (far too much). My question is - can I swap the valve connections around...

    Vibrating/hammer controlled by TRV

    Hi We’ve been having a loud vibrating from our CH pipes upstairs. Very annoying because it seems to be directly underneath the babies room meaning we can’t have the heating on after bed time. It can actually be controlled or induced by turning the little ones TRV down once a certain heat...

    Honeywell TRV leak- type of pipe fitting

    Hi I removed a radiator to decorate and when refitting had to undo the bottom nut of the TRV to turn the head slightly, once everything was back in place I nipped up the nut but it’s weeping. I’m resigned to draining the system but I just want to check if this type used a 10mm olive so can...
