One of our showers the hot water suddenly quit working. Works fine in other showers.

Hi Cgoebel and welcome, you need to post what type of shower valve you have for the best answers. Good luck

Yup! A brand name and an approximate age of the valve will help tremendously!

Symmons shower valve is famous for this, but it is a quick/easy job to resolve it!

Post back with more info...
