Our small radiator came away from the wall and buckled the pipe coming up from the floor. As a result of this all the water in the system then started shooting out from the small hole. Can this be "capped"? We have used Evo-stik plumbers mait putty to stem the flow as well as switching off the system. Can the pipe be fixed or are we clutching at straws? Thanks

What material is the pipe? Copper?
