What is required when reassembling a trap after cleaning?

When reassembling a trap after cleaning, using new gaskets is essential for several reasons. Gaskets are designed to create a seal between components, preventing leaks of steam, water, or other fluids that the trap is managing. When old gaskets are reused, they may not provide an effective seal due to wear, deformation, or degradation from heat and pressure exposure. This can lead to leaks, which can compromise the efficiency of the system and potentially cause safety hazards.

Using new gaskets ensures that the trap will function correctly, maintaining the intended pressure and flow rates while reducing the risk of leaks. Additionally, new gaskets are typically made from materials that can better withstand the operating conditions, thereby improving the longevity and reliability of the steam trap.

While other practices, such as applying sealants or conducting high-pressure tests, may be relevant in specific contexts, they do not substitute the need for new gaskets, as the primary purpose of a gasket is to provide a tight seal between surfaces.
