A fitment for providing leak protection at a frost-free hydrant has a protective sheath having a bore of a first diameter. An escutcheon plate is formed at an outer end of the sheath to define an aperture for receiving a frost-free hydrant into the sheath. The sheath is made longer than any of a range of frost-free hydrants to be received therein and has an end cap sealingly connected to an inner end of the sheath. The end cap has a reducing section and an end section having a bore of a second diameter smaller than the first diameter, and dimensioned to receive a link pipe in a sealing connection, the link pipe being of a length to bridge the distance between an inner end of the hydrant and building water supply equipment. In use, the hydrant with link pipe attached is inserted into the protective sheath and the combination of the hydrant and sheath is fully into the wall through a hole in the wall. The link pipe is then sealingly connected at the second diameter bore and to the building water supply equipment. |
