The Most Positive Method to Test a Trap
What is the most positive method to test a trap to ensure it is working?
a) Touch the body of the trap
b) Observe the discharge by means of a test valve
c) Check the temperature of the inlet and the outlet
d) Remove the trap for bench testing
e) Replace the trap with a new one
Answer:
The most reliable method to test if a trap is working is to observe the discharge through a test valve, offering direct visual evidence of its functionality.
The most positive method to test a trap to ensure it is functioning properly is to observe the discharge by means of a test valve. This method provides direct, visual confirmation of whether or not the trap is operational. Options such as touching the body of the trap or checking the temperature of the inlet and outlet can give indications of performance but are not as definitive as observing the trap in action.
Removing the trap for bench testing and replacing the trap with a new one are more time-consuming and may not be necessary if a simple visual check via a test valve can suffice.
