Abstract

The invention relates to a method of modifying a hydrant (10) of a type having a deviated throughbore extending between an inlet (20) of the hydrant and an outlet (38) of the hydrant to form a hydrant (10') having a substantially straight throughbore. In the disclosed embodiment, the method comprises the steps of inserting a seal element (46) into the hydrant through the outlet; actuating a valve (24) of the hydrant to open the inlet; directing the seal element into the inlet and closing the inlet using the seal element; removing a bonnet assembly (22) of the hydrant which carries the valve and which defines the hy drant outlet from a body (18) of the hydrant which defines the hydrant inlet; and mounting a replacement bonnet assembly (48) on the hydrant body, the replacement bomnet assembly defining an outlet (50) of the hydrant which is arranged relative to the hydrant inlet so as to define a substantially straight throughbore extending between the inlet and the outlet. The invention also relates to a hydrant bonnet assembly suitable for use in a method of modifying such a hydrant, a kit for use in modifying such a hydrant, and to a modified hydrant incorporating such a hydrant bomlet assembly.
