ABSTRACT:
A method of making a replacement valve assembly, and the replacement valve assembly are provided in which an existing valve assembly is removed from the valve and used as a guide to make the replacement valve assembly. A threaded rod is cut to a length in accordance with the removed existing valve assembly and stock sleeve material having an internally threaded bore therethrough matching the external threads on the threaded rod is cut in accordance with the existing valve assembly to form a stem on the replacement valve. The valve assembly operating threads are cut from a piece of stock material having an internally threaded bore and a matching valve element is selected to match the one on the existing valve assembly. The externally threaded rod is coated with flux and a liquid solder or is cleaned and coated with a polymer adhesive and the cut and selected items assembled thereon to form the replacement valve assembly. The assembled unit is heated with a torch if solder is used or is cured in the case of a polymer adhesive. In most cases, the handle attaching stem portion having an internal threaded bore is attached to one end of the cut threaded rod and an internally threaded washer may be attached where a stop is required for the valve assembly. Washers and O-rings and miscellaneous items are also required.
