We need the make and type of your valve. One handle or two knobs? Temp controlled or Posi-Temp valve? How old? L<et me know, Tom

One handle, brand new, and how do I tell if it is temp controlled or posi-temp valve? It says temptrol on it but looks almost like brand name maybe? Also to add we have have hot water in sink in kitchen and its consistent.

No we are renting and was installed before move in. Looking at diagram looks like the correct one though? Is this something I can take apart and control temperature of?

If you are renting you must check with the owner or manager regarding any plumbing repair. First off they probably don't want you messing with their unit and secondly they are responsible for the repairs. Call the owner or manager.
