CA 2565555

A backflow prevention device includes a main body holding a removable cartridge. The removable cartridge houses two independently acting check valves and, optionally, a relief valve. A first portion of the cartridge may be retracted into a second portion of the cartridge, thereby reducing the overall length of the cartridge and facilitating the removal of the cartridge from the main body without the need to remove the backflow prevention device from a water supply system. The relief valve is contained in a removable cartridge. Each check valve may have a self cleaning plunger bore comprising at least one spiral groove.
