A freezeless wall faucet comprising: an elongated faucet housing having an elongated bore extending therethrough, said bore having an inner end adapted to be connected to a pressurized source of fluid and an outer end, said housing having an outlet nozzle in communication with said bore adjacent said outer end of said bore for permitting fluid to exit from said bore; a valve cartridge removably inserted within said bore and comprising sealing means, valve means, an elongated tube assembly having a tube bore extending therethrough and having an outer cylindrical surface, said tube assembly having a first end connected to said sealing means and a second end connected to said valve means, a handle connected to said sealing means, an elongated operating rod extending through said tube bore and being longitudinally movable therein, said rod having a first rod end engaging said handle and a second rod end engaging said valve means; said cartridge being removable from an inserted position within said bore wherein said sealing means sealingly engages the wall of said bore adjacent said outer end thereof and said valve means is positioned within said bore adjacent said inner end thereof to a removed position wherein said entire cartridge is removed from said bore through said outer end thereof; locking means on said housing and movable from a locked position wherein said locking means engages said cartridge to prevent removal of said cartridge from said inserted to said removed positions to an unlocked position wherein said locking means permits removal of said cartridge from said inserted to said removed positions; said nozzle being between said valve means and said sealing means when said cartridge is in said inserted position; said valve means comprising valve sealing means sealingly engaging said wall of said bore when said cartridge is in said inserted position; said valve means being movable from a closed position preventing fluid flow from said inner end of said bore to said nozzle to an open position permitting fluid flow from said inner end of said bore through said bore to said nozzle and outwardly through said nozzle; said handle being movable from an off position to an on position for causing longitudinal movement of said rod within said tube assembly so as to cause movement of said valve means from said closed position to said open position; backflow preventor means movably mounted on said outer cylindrical surface of said tube assembly adjacent said valve means for longitudinal sliding movement to said tube assembly between a forward flow position wherein fluid is free to pass from said valve means to said nozzle to a backflow position wherein said backflow preventor means blocks the reverse flow of fluid from said nozzle through said valve means to said inner end of said bore, spring means yieldably holding said backflow preventor means in said backflow position and being yieldable to permit movement of said backflow preventor means to said forward flow position in response to fluid flow from said inner end of said bore through said valve means toward said nozzle; said backflow preventor means being carried by said cartridge when said cartridge is moved from said inserted to said removed position.
