1. We opened an access at shower to determine where the leak was and why. We determined that the shower arm is loose and spraying water forwards which is running down wall in side tub. We recommend removing the shower head and re-installing with tight seal to stop leak. There appears to be damage at the base of shower where the water has leaked down wall. We recommend remediation or drywaller to remove and repair drywall. 2. The toilet is loose. We recommend pulling toilet and resetting. It might need a new toilet flange or just need to be reset with a new wax ring and hardware . 3. The venting on the water heater is older and is recommended to have it replaced from the top of the water heater to the roof. The water heater vent is not shared with any other fixture.
