1. Utilize temperature to ensure the trap is "live". Steam must be on to test a trap.
2. If all valves are open, steam is on, the process is calling for steam, and the trap is cold then it has failed in the closed position and should be replaced immediately. Please ensure the trap selected is proper for the application before replacing.
3. If the temperature of the trap is significantly warmer than ambient temperature it is not failed closed and requires additional inspection:
- We recommend utilizing an ultrasonic leak detection tool, let us know if you need to know where to purchase one.
- Inverted bucket and thermodynamic steam traps are easier to test as they have an on/off cycle. Just listen to the trap long enough to ensure it cycles open/closed.
- Float & Thermostatic, balanced pressure, and bi-metallic are more difficult. You will need to listen to the velocity sounds. Please call to discuss until we can put a video together.
