Abstract

A method for replacing an existing service pipe carrying fluid to an outlet within a property with a replacement service pipe, the method comprising disconnecting within the property the outlet from the existing service pipe in such a way that both during and after disconnection fluid is prevented from escaping into the property, feeding into the existing service pipe a desired length of a replacement pipe 18 in such a way that during and after the feeding step fluid is prevented from escaping into the property, connecting the outlet to the outlet end of the replacement pipe in such a way that during the connection fluid is prevented from escaping into the property, after connection allowing fluid to pass to the outlet solely by way of the replacement pipe and after the replacement pipe has been fed into the existing pipe, injecting a sealant e.g. through nozzle (78) between the replacement and existing pipes up to a point adjacent to the leading end of the replacement pipe.
