Thanks! Would I need to change the other side to a lockshield that came with the TRV, or could I keep the current one (manual wheel style)? Also, the valve said it was bi-directional, so I'm assuming it's not an issue which end of it goes into the different valves, I.e. so I can put it...

That's really helpful, thanks - I'll give it a go. So regarding valve tail, if I remove this, the smaller one will just screw in, despite being smaller? Or would I need to use something like this? https://www.screwfix.com/p/bush-x/98427

Thanks for this - in terms of the valve tail from the rad, would it be a straight swap, as the outside diameter seems thicker, or would I need to covert it somehow? Regarding the olive and nut from the copper pipe, how would I go about removing this?

Hi All I just tried to switch my vertical radiator from a traditional valve to a TRV. I bought a 15mm TRV. However, upon going to switch the valve, I have come across a few issues: 1). The pipe leading to the wall is 15mm, however, the nut behind it is too big to lock onto the new valve. 2)...

Actually, I had realised that on the towel radiator, the other valve (non-TRV) was tightened too much, which was stopping any hot water entering it, as the pin was completely depressed. However, now I've opened it up more, the radiator is permanently on, despite the TRV stating that it should...

It does indeed (hot water). I've checked both sides and realised that the TRV side is a bit rusty and stiff. When I manually held the pin down, it heated the radiator. However, once I put the TRV back on and tried to heat it up, it isn't heating...! Perhaps the pin is too stiff for the TRV to...

Brilliant, that worked - thanks very much! My only next issue is that my towel radiator isn't working... it stopped recently. I've changed it over to the Tado TRV and it still isn't working. I've tried pressing the pin in at both sides to make sure it isn't stuck and that hasn't worked. I've...

Apologies, see attached. The water doesn't appear to be calling, no! I've pushed the test button and I didn't hear the fortic tank heat up etc.

I took the old thermostat off the wall and put wago's on (picture attached). It seems that the hot water is not on either!

I've installed it as you said (picture attached) and have installed and connected all of my Smart TRV's (including via the app). However, none of the radiators are turning on when requested via the app... I don't suppose anyone has any ideas why?! With the old controller when I turned on the...

Grand, thanks very much!

Hi All I was looking to change my Potterton EP2 over to the Tado Smart Wireless V3 controller. I was hoping someone might be able to help me witn the wiring? Wasn't sure whether this was better suited to this area, or Plumbing & CH... From the Tado diagram (attached), it seems I need to add...

Hi All I was looking to change my Potterton EP2 over to the Tado Smart Wireless V3 controller. I was hoping someone might be able to help me witn the wiring? From the Tado diagram (attached), it seems I need to add connectors between Live & CH COM & HW COM. I have attached a picture of my...

Grand, thanks! I had further comments from the plumber, who said he didn't think I'd need one, as I have a manual bypass and three port valve which never stop flow. I'm presuming this (including the three port valve) was in line with what you were saying?

Great, thanks for the advice! Would you say that both valves need to be changed (TRV & lockshield), or just swapping over to the TRV?

Thanks for all the replies everyone. Just FYI, before coming on here put out some feelers with local trades people. In line with your view BlueLoo, one came back and said I shouldn't need an ABV as I have a three port valve and a manual bypass. In terms of changing over the manual valve on the...

Thanks for this - I had seen some videos in which people had left the gate valve open a half turn to satisfy the boiler and was hoping that this might be the case here. Looking at the manuals left by this area, it appears I have a Honeywell V4073A Motorised Mid-Position Valve. By the boiler in...

Thanks for the reply. I believe that the HW/CH are controlled independently. Do you know how I would tell / where I would need to look to see if I do have an automatic bypass valve in the piping network? I had assumed it would be in the area I took the picture of (which is next to the fortic...

Hi All I've just bought some Tado smart radiator thermostats (awaiting delivery). I've checked all the radiators and they're all TRV's (including towel radiator), expect one, which has two manual valves. I am assuming this is perhaps a bypass radiator, however, my impression was generally...
