Water heaters need pans under them to collect water in the event that the tank fails. In garden style homes, the overflow pan must be connected to the recently installed drain lines that run from the third floor to the ground.
In both town homes and garden homes, water heaters should be checked monthly for possible leaks. To do this, run your hand under the tank and around its perimeter to check for moisture. If the area is damp, shut off the tank and immediately call a plumber.
Water heaters are notorious for failing at about the same time as the manufacturer's warrantee expires. Most water heater failures are discovered when home owners find themselves walking though a layer of water on the floor. If your water heater has exceeded its life expectancy or is approaching it, you should consider replacing it now to avoid costly damage and a major inconvenience.
Water tanks must vent through the existing flue/ chimney only. Exterior wall penetrations for water heater venting is prohibited.
