This week's question:
A replacement water heater in a residence was installed inside a utility room, located approximately 12 to 15 feet from the building exterior. The building construction is a conventional raised floor with a crawl space. The water heater is installed in a pan. The temperature and pressure relief valve terminates into the pan which is drained into the crawl space. The Code states that the pan shall drain to an approved location. Can the pan drain into the crawl space, as opposed to being piped to the building exterior?
