Upon arrival, the customer showed us the issue with the master toilet, explaining that the valve had come off and the toilet was continuously running. After assessing the situation, we suggested replacing both emergency stop valves in both bathrooms for the toilets and performing a minor rebuild in the master toilet to resolve the running issue. We proceeded with the work as discussed, replacing both valves and completing the rebuild in the master toilet. After completing the repairs, we checked for leaks and confirmed that there were none.
