The question

A technician used a solderless piercing access valve on a window air conditioner. What should be done with it when the job is finished?

• ARemove it, because these fittings tend to leak over timeCorrect answer
• BLeave it so the next technician can use it
• CLeave it, as long as its cap is tight
• DRemove only the valve core and leave the clamp body in place

Why “Remove it, because these fittings tend to leak over time” is correct

EPA's test topics say technicians should remove solderless access fittings at the conclusion of service. They are a quick way into a sealed system, but they are not a permanent seal and can leak later.

Why the other answers are wrong

• Leave it so the next technician can use it — Leaving it in place risks a slow leak; EPA's test topics say to remove it.
• Leave it, as long as its cap is tight — A tight cap does not stop the fitting itself from leaking over time.
• Remove only the valve core and leave the clamp body in place — The whole solderless fitting should come off at the end of service.
