    Decorative TRV Caps?

    Does anyone know a good source for decorative chrome TRV replacement caps? I'm slowly working my way through a property, putting all the rads on to a manifold system with local thermostats, manifold flow meters, adjustment for balancing and electrical actuators for each room. So the TRV heads...

    Movement between TRV and radiator.

    Hi, Can anyone tell me if there is supposed to be any movement between a TRV and the radiator, as have replaced a radiator and tightened the connections as much as possible, but the TRV can still be moved backward and forward. Many thanks, Von 🤔 🤔 🤔

    Remote sensor trv working or not.

    Not used or come across these before. Went to look at a radiator today. Not working. It has one of the sensor trvs on it. I can't get my hand into the boxing to take head off. Do these have a pin in the valve like a usual trv. They are arranging a builder to dismantle the radiator housing. The...

    what should i expect to pay per radiator to have a trv fitted? I'm in Somerset.

    Hi, my first post. What should I expect to pay to have 6 new TRV's fitted (per rad)? Is it a job I could do myself with reasonable DIY skills? Thanks for any help. David

    Replacing TRV on radiator, 15mm pipe to 22mm radiator

    I’m trying to replace my TRV on my radiator but have found that my pipes are 15mm copper but the radiator has a 22mm radiator tail. There isn’t enough space between the valve and the radiator/pipes to fit a compressor (which is what I think I need...) the old broken valve looks like it goes...

    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...

    Advice needed on radiator valve

    Hi all, this is my first post so hoping I've got it in the right section. 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. Do I simply need to undo the nut at the top & slot a new head on or does the old fixing need to...

    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. Basically, they ‘work’ when heating starts from cold but then trv shuts off and never cuts back in. So for example - heating...

    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

    Hi Guys, got called out to look at a noisy rad and this is what i found, see attached vid clip, or not... sound is pulsed rapid tapping all single panel rads are making the noise to some degree and at first I thought it was due to no anti vibration clips fitted.

    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...

    Single Pipe Valve / TRV Help

    I have a single pipe system (Yes I know most people will say upgrade to 2 pipe). I have installed Honeywell TRV and have some issues (Rads not getting hot) which I believe are due to the TRV (reduced flow), have tried bleeding rads, balancing etc. If I take the TRV head off they heat, put it on...

    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...
