Drip pan over flow pans, hints from a home inspectorDrip pan over flow pans. Drip or catch pans placed under the water heater are recommended by manufacturers and are required by many municipalities, but is rarely enforced. The inspector will not comment on the lack of a catch pan. A catch pan placed under the water heater with a drain line connected and piped to the building exterior would obviously be a good precautionary action against water heater leaks. Contact the inspector for additional information regarding the stand and/or catch pan if you desire. The temperature pressure relief valve (also called tp valve, pt valve, t and p valve, srv, etc.) Is an important component added to the water heater. Should something go wrong that allowed the water heater to continue heating the water past the point of safety (from excessive pressure or temperature) the properly operating and installed tp valve would release built-up pressure and hot water to a safe discharge point. The pressure temperature relief valve output should always be directed outside the building and downwards, about 6 to 12 inches off the surface of the ground or flatwork concrete. If the temperature pressure valve drips, it should be replaced. Improperly installed tp valves should be removed and replaced. Be dependable. Setting the water heater thermostat to a reasonable temperature (approximately 120Ý f) is advised.
