Abstract
A plumbing part in the form of a water delivery device is comprised of a protective liner through which potable water can flow. The protective liner is in the form of one or more lengths of stainless steel tubing and is encased in a casting of a desired material, such as bronze or brass. Fittings required to attach the water delivery device to sinks, bathtubs or other water sources and to allow for insertion of various aerators and other flow devices are also encased in the casting. The various fittings are pre-assembled to the liner prior to casting to ensure a water-tight seal between the liner and the fittings prior to casting.
Claims34
A water delivery apparatus, comprising:
- an exterior casting formed from molten metal having an inlet at a proximal end and an outlet at a distal end;
- an interior liner extending from proximate said proximal end to proximate said distal end;
- and
- a sleeve attached to said proximal end of said casting and placed at least partially over said interior liner proximate said proximal end, said sleeve allowing contraction of said casting relative to said liner during the casting process.
A water delivery apparatus, comprising:
- an exterior casting formed from molten metal having an inlet at a proximal end and an outlet at a distal end;
- at least one segment of stainless steel tubing forming a waterway within said casting;
- and
- an expansion sleeve attached to said proximal end of said casting and placed at least partially over said at least one segment proximate said inlet, said expansion sleeve allowing contraction of said casting relative to said tubing during the casting process.
A water delivery apparatus, comprising:
- an exterior casting having an inlet at a proximal end and an outlet at a distal end;
- an interior liner extending from proximate said proximal end to proximate said distal end, said liner and said casting forming an annular space therein between along at least a portion of said liner;
- and
- a sleeve attached to said proximal end of said casting and placed at least partially over said interior liner proximate said proximal end, said sleeve allowing contraction of said casting relative to said liner during the casting process.
