  1. Which appliance installation code specifies that a clothes dryer must be exhausted to the outdoors?

    Answer: IRC Section M1502

    IRC Section M1502 requires dryer exhaust ducts to terminate outside the building and prohibits exhausting into attics, crawlspaces, or walls.

  2. When installing a replacement dishwasher, the drain hose must be looped up to cabinet height or fitted with an air gap. Why?

    Answer: To prevent backflow of drain water into the dishwasher tub

    A high drain loop or air gap creates a physical barrier that prevents contaminated sink drain water from siphoning back into the dishwasher.

  3. A technician is removing a wall oven for recycling. The oven is hardwired. What is the FIRST electrical step?

    Answer: Turn off the dedicated circuit breaker and verify absence of voltage

    The circuit breaker must be turned off and voltage verified absent before opening any junction box or touching wiring to prevent electrocution.

  4. What is the maximum allowable length for a flexible gas connector used on a residential range in most US jurisdictions?

    Answer: 6 feet

    Most US codes limit flexible gas appliance connectors to 6 feet in length to minimize the risk of damage or accidental disconnection.

  5. During a recycling pickup, a customer's refrigerator is found to contain R-134a. Which statement is TRUE about R-134a?

    Answer: R-134a does not deplete ozone but still has a high GWP, and venting it to the atmosphere is prohibited

    R-134a is not ozone-depleting but has a high global warming potential (GWP=1430); EPA rules prohibit venting it and require proper recovery.

  6. When positioning a new refrigerator after installation, why should it be slightly tilted backward (front higher than rear)?

    Answer: To improve compressor oil return and help the doors swing closed by gravity

    A slight backward tilt allows refrigerator doors to swing closed by gravity and improves oil return to the compressor during the off cycle.

  7. What is the correct procedure if a bubbling sound is heard at a gas fitting connection after installation?

    Answer: Apply soapy water to the fitting — if bubbles form, shut off gas and re-seal the connection

    Soapy water applied to a gas fitting will bubble visibly at any leak point; if confirmed, the gas must be shut off and the connection re-sealed before use.
