Hello,
I’m wondering if you clever people can help me track down some compatible TRV heads. I now have three that don’t work. The valves and pins work fine so I was optimistically hoping to be able to just replace the heads.
They have British Gas or Celsia branding written on the top and I would guess that they are at least 20 years old. There are some pictures attached.
However, having tried three local plumbing shops today, no one was able to find a head that properly fits. It seems the collar on my heads is deeper than the collar on heads that are readily available. As an example, this head from screwfix nearly fits but the collar isn’t quite deep enough. https://www.screwfix.com/p/white-angled-thermostatic-trv-15mm-x/60368
Does anyone know of any compatible heads, or do I need to resort to replacing the full valves?
