radiator valve

I have a new house with a mess of a heating system. A couple of the radiators have these valves which have a screw on cap. They do not seem to be adjustable like a lock shield valve (thought one does turn a little with a wrench). So.. I am wondering what exactly they are, what they're for...

Hi All, one of my radiators does not a valve installed. Here is picture of it: Do you have any advice what kind of valve I need and how I can install it without opening thr pipe system? Thank you in advance.

Hi, I’m struggling to find which adapter I need for my hive smart valves. Any ideas? The photo with adapter is the M28 which hive subsequently provided when I discovered the standard adapters also didn’t fit. For context, it’s an old house. We’re also on oil just in case that might help to...

How do I change a TRV on a pressurised system? A couple of weeks ago, I noticed the bathroom floor had 'dried water' underneath the towel rail / radiator. I checked the radiator for leaks, and it was bone dry all around it and the connecting pipes. I left it for a few days, keeping my eye on...

I'd like to fit this vertical radiator closer to the corner, but would need to leave a gap for the valve so there isn't really enough room. Is there a compact double-elbow solution for mounting the radiator valves under the radiator, so I can move it closer to the corner? The 10mm Speedfit...

I am plumbing in some additional radiators and would like to clarify which way around the valves should go. Does the check valve go on the side where the water goes into the radiator or the side where it flows out? I have been trying to clarify, but have read some guides which say to fit it to...

I have a problem with one of my new Hive Heating thermostatic radiator valves that I got last month, it has stopped responding to manual temperature changes via the valve it's self, but the valve still wakes up when you go to manually adjust it as shown in the video. Have I accidentally enabled...

Hi All, I have fired up my central heating system for the first time in a few months to find that all my radiators are working fine, except one in my upstairs bathroom. The valve knobs are turned fully open (picture attached) but radiator stone cold. I tried a few things but to no avail. The...

1) Any idea what “bonding required before first tee” means? this was written on my gas safety certificate (CP-12). I have tried to look it up and I think it is something to do with a plumbing joint (for a radiator?). Does a plumber need to do this? 2) radiator valve leaking. Does this mean I...

Hi, I've just had a bathroom towel heater replaced in my bathroom. The old one had two pipes going into it (as does the new one), one of the had a numbered thermostat on it so I could change the temperature on it. I should mention that the towel radiator runs on the hot water as opposed to...

Hi, I cannot seem to remove the cap on the valve in the picture. Is it definitely just pulling it off that should work? The radiator doesn't warm up at all, so trying to see if it is the thermostatic valve that is closed, as when bleeding it no air came out. I managed to unscrew the end part...

Hi everyone, I've set the on/off cycles for both HW and CH differently. Irrespective of the whats shown on the display (Auto, On, Off etc), both CH & HW seem to be always on ie if I open the tap, the water is hot and if I open the TRV, it turns on the radiator. I'm renting an apartment. I...

Hi, I'm doing some decorating and need to take a radiator off the wall. I've done this a few times before however I've never seen a lockshield value like this one before where the spindle is completely round. Does anyone have any idea how to tackle this? Thanks in advance

Hi all, hoping you can help? I've fitted a Drayton Lockshield Valve to a new radiator pipe prior to installing a new radiator which hasn't arrived yet. However the valve is leaking slightly from the opening, not the nut and olive. How do I turn it completely off? I've tried tightening the cross...

Hi, Can anyone tell me what the following radiator valve fitting is? It's located between the radiator and the lock shield valve - it seems to have a screw in the top but I've no idea what it's for as I've never seen one before. Any ideas? Thanks :)
