FAR UFH mixing valves replacement!

[Hendog]

So I have a customer with a leaking mixing valve on his UFH manifold, my boss sent me there today with a full new manifold as the supplier has said they are discontinued but the customer said he doesn’t want it all replaced since it works well.

Iv looked at the FAR website and emailed them but they don’t answer the phone so I’m hoping to find a valve that could replace the termo far mixing valve without changing the manifold.

It’s a huge house in London with 5/6 floors and 3 manifolds, im not very experienced with UFH but I’m convinced someone must have encountered a similar issue.

Any advice would be much appreciated

Does anyone even know what size the connections maybe so I can at least source a similar replacement?
Would you say inch?

Thanks

this pump connection looks standard to me in terms of thread/nut size but the adapter is unusual

Thanks rodders
Amazingly that supplier is who I’m already dealing with and in my area so Iv actually popped in and had a chat.
The sticking point is that the existing valve is old and different dimensions, being very inexperienced in UFH I didn’t get the dimensions from pipe centre to edge and to replace the existing valve without changing the manifold and pump may not be possible without the exact adapters.

I’m unable to even find the model or data sheet and as it’s in Chelsea about 3 hours and a ULEZ charge away I need to ensure I have what I need with me.
