I have an old Grohe thermostatic shower valve. After replacing the hot water heater, the water no longer gets above 85 degrees in this shower. Had several plumbers look at it and they all gave up. So, I am attempting DIY adjustment. This is as far as I can get. Any ideas on what to try to increase temp? Cold water is cold. Hot water is Luke warm. Sinks have no issues. Plumber recommendations in the Atlanta area?
