The shower mixer valve won't shut of the water so it needs to be either replaced or repaired but I don't know what type it is. Does anyone recognize it from the picture I have attached. It is circa 2004 for a Persimmon built home.
Replacement with a different newer type would not be a good option because I would have to re-tile the whole bathroom because of the cutout shape/size. The oval plate in the picture seems to be bigger than any possible replacements I have found
Thanks In Advance
