The existing one has acl Lifestyle on the top.
The ones that are too big are a Honeywell and a Screwfix one (SKU 60368-001)
Do you know what may replace the ACL valve?
I have bought a TRV valve to use the top section to replace a broken one on an existing valve. The new one has a larger thread size so won't screw on. Does anyone know if both thread sizes are available?
Many thanks if you can help.
