BACKFLOW PREVENTION VALVE AND METHOD OF PREVENTING BACKFLOW DURING WATER SUPPLY
A backflow prevention valve (30) prevents backflow during the supply of water from a mains supply to a separate water system, for example a water tank on a boat. The backflow prevention valve (30) is provided comprising a valve body (32) defining a chamber (34), an inlet (36) opening into the chamber (34) and arranged on an inlet axis (38), an outlet (40) opening from the chamber (34) and arranged on an outlet axis (42), and a funnel arranged in the chamber (34) around the outlet (40). The outlet axis (42) is substantially collinear with the inlet axis (38). The funnel tapers from a first larger perimeter at a first end (48) to a second smaller perimeter at the outlet (40). The chamber (34) has one or more backflow outlet ports (52) arranged outside the first perimeter of the funnel.
