A backflow valve/valve extractor combination. A valve body is provided with a flow channel in which is positioned a valve seat. An access opening provides access from above to the valve seat. A valve receptacle is positioned on the valve body along a peripheral edge of the access opening. A valve is provided having a main body and a pivotally mounted gate. The main body has a profile which is adapted to be received in the valve receptacle. An extension handle is secured to the main body of the valve. This permits a person exerting a force upon the extension handle to disengage the profile from the receptacle and pull the valve through the access opening and to surface through an access pipe.
