Final answer:
The cap membrane end laps around a circular accessory should meet at the least exposed point to minimize water ingress and ensure a durable seal.
Step-by-step explanation:
When installing the cap membrane around a circular accessory, the end laps should ideally meet at the point of the accessory that is least exposed to water flow or weather conditions. This location minimizes the potential for water ingress and provides the best chance for a durable seal. It is important for the installation to be meticulously done, ensuring that the end laps are properly sealed to prevent any leaks.
