The cold water tap failed to close completely after 11 years of service. It was tricky finding the right insert to fix it. It has a different configuration than any common ceramic insert sold at the local hardware store.
The make is Scandvik. When I called customer service, they were very helpful and sent me the correct parts. The faucet/tap information is following:
Compact ceramic cold water tap with a tall swiveling and folding spout. Vertical or horizontal installation. Spout folds and swivels for minimum obtrusion when tucked away.
Water Connection: 3/8" BSP threaded shaft with 1/2" NPS-M Nylon adaptor included.
Material: Chrome plated brass
Mounting Hole: 5/8"
Shipping Weight: 3 lbs.
The valve insert is described as "VALVE ON/OFF COLD RIGHT FLDNG CERAMIC FAMILY"
The part number is 10427. 2016 pricing was $26.00.
