Describe the function of a trap primer

Function of a Trap Primer

A trap primer is a crucial component in plumbing systems, especially in commercial buildings where floor drains are commonly used. The primary function of a trap primer is to add water to the trap to replace water lost through evaporation. This action helps ensure that the water seal in the trap remains intact, preventing foul odors from sewage systems from entering the building.

Preventing Odors and Maintaining Water Seal

When water evaporates from the trap, the seal that prevents sewer gases and odors from coming into the building is compromised. The trap primer addresses this issue by automatically adding water to the trap at regular intervals. By maintaining the water level in the trap, the primer prevents the escape of odors that can cause discomfort and health hazards to occupants of the building.

Connection to Fresh Water Supply System

The trap primer is typically connected to the fresh water supply system of the building. It draws water from this source and releases it into the trap, ensuring that the water seal is continuously replenished. The frequency of water release can be adjusted based on the specific needs of the plumbing system and the rate of evaporation in the trap.

Importance in Plumbing Systems

Overall, the trap primer plays a vital role in maintaining the functionality of plumbing systems by preserving the integrity of traps and preventing odors from sewage systems. Without a trap primer, traps can dry out, leading to unpleasant odors and potential health risks. It is an essential component that contributes to the overall efficiency and safety of building plumbing systems.
