With these installed it makes loop maintanence so much more bearable, since fully draining a loop can be near impossible. Being able to pop these apart and then pulling each component out piece by piece just makes things a breeze. Review: Disconnects with almost imperceptible leakage - Easy to connect and disconnect.
