Client is experiencing a leak underneath the shower in the master bath when the water is running Search for a leak coming from the master bathroom shower, cut open drywall behind the shower valve and under the shower trap to identify where the leak may be coming from. After careful examination, we finally identified the leak was coming from the shower pan itself and the caulking needed to be redone. I recommend redoing the caulking for the entire shower to prevent leaks. I confirmed the leaks are not plumbing related. A tile and grout company will be coming out to do this. Recommended property medics come out to assess the water damage, while it is not catastrophic. it appears to have been going on for a long time. Water heater is 12 years old. Left estimates for replacement. Water pressure is at 75 psi
