Tundish

According to Approved Document G (Sanitation, hot water safety and water efficiency), 2015 edition, a tundish is:

'…a device, installed in the discharge pipe from a valve, that provides an air break allowing discharge to be conducted safely to a place of termination. The tundish also provides a visible indication of a discharge and functions as a backflow prevention device.'
