Our shower is 11 years old and has been great. The water will not get hot, we can feel the hot water right up to the mixer unit . Please can you help...we dont want to replace it if possible,. also do you know where we can get parts? the number on the original paperwork is now unatainable
Never seen a shower valve or mixer valve that couldn't be repaired from inside the shower in most all cases if that helps. Running down the necessary parts is another thing. I would call an experienced plumber.
