Plumbing live connection. We can't shut the water off to this aged care facility without individually notifying 100 residents 24 hours before. Needless to say when we need to service a tap we find other ways around it. In this video I cut the pipe, slide on a valve with a crimp fitting attached. The fitting is crimped witht the viega press tool and then the valve shut off. From there we can work on the tap at our leisure. Happy days!
