I'm having an issue with the hot water in the shower. We've been in the house a few months now and the hot water in the shower isn't hot like it was when we first moved in and it becomes colder much much faster. All of the faucets in the house still get very hot and have no trouble staying hot so I think it would just be something to do with the shower. Any suggestions?? Thanks!
See if you can find instruction sheets for installation of the brand you have. Once the handle and finish piece around the valve (2 screws?) are removed, there are adjustments on the inner valve to balance hot and cold levels. And limit devices to restrict hot water temp.
Suspect young children were previously in the house.
