The shutoff valve and visible water supply connectors appeared functional. A temperature & pressure relief valve and discharge line are installed, and routed to the exterior.
Although I wasn’t able to see a date of manufacture, the water heater looked as though it might be past it’s life expectancy of 10 years and will need to be monitored for leaks and serviced regularly. I recommend installing a drain pan & discharge pipe to the exterior, to catch and divert any dripping water to the exterior. I also recommend a home warranty policy in place to cover older appliances.
