A test fitting for installation in a plumbing system comprises an annular sleeve having opposed first and second open ends and an inner surface that defines an open interior space and a hole. A cord has a first portion removably positioned in the sleeve's interior space and a second portion extending through the hole for removing the cord from the interior space through the hole. The first portion of the cord forms a watertight spiral disc that extends across the interior space to define a first area completely separated from a second area, and an outer edge of the spiral disc may be supported by a ledge extending from the inner surface into the interior space. Means are included for selectively sealing the hole after the cord is withdrawn through the hole, such as a plug complementary to the hole.

What is claimed is as follows: 1. A test fitting for installation in a plumbing system, said test fitting comprising: an annular sleeve having opposed first and second open ends and an inner surface, said inner surface defining an open interior space and a hole; a cord having a first portion removably positioned in said sleeve interior space and a second portion extending through said hole for removing said cord through said hole, said cord first portion forming a watertight spiral disc extending across said interior space to define a first area completely separated from a second area; and a plug complementary to said hole for selectively sealing said hole after said cord is withdrawn through said hole; wherein said sleeve includes a ledge extending from said inner surface into said interior space for selectively supporting an outer edge of said spiral disc; wherein said hole extends through said ledge; wherein the plumbing system comprises a plurality of pipes; wherein one of the pipes abuts a first side of said ledge; wherein another of the pipes abuts a second side of said ledge; wherein said test fitting further comprises means for attaching said sleeve first end to the one of the pipes and means for attaching said sleeve second end to the another of the pipes. 2. A test fitting for installation in a plumbing system, said test fitting comprising: an annular sleeve having opposed first and second open ends and an inner surface, said inner surface defining an open interior space and a hole; a cord having a first portion removably positioned in said sleeve interior space and a second portion extending through said hole for removing said cord through said hole, said cord first portion forming a watertight spiral disc extending across said interior space to define a first area completely separated from a second area; a plug complementary to said hole for selectively sealing said hole after said cord is withdrawn through said hole; and a sheathing encompassing said inner surface and defining a sheathing hole adjacent said inner surface hole; wherein the plumbing system comprises a plurality of pipes; wherein said sheathing includes unattached and overlapping first and second ends; wherein said test fitting further comprises: a first hose clamp adjacent said sleeve first end and outwardly adjacent said sheathing for attaching said sleeve first end to one of the pipes; a second hose clamp adjacent said sleeve second end and outwardly adjacent said sheathing for attaching said sleeve second end to another of the pipes. 3. The test fitting as in claim 2, wherein said sheathing first and second ends are distant from said sheathing hole. 4. The test fitting as in claim 2, wherein said first and second hose clamps include color indicia to visibly differentiate said test fitting from the remainder of the plumbing system. 5. The test fitting as in claim 2, wherein: said sleeve first end includes a plurality of consecutive ridges to seal said sleeve first end to said one of the pipes; and said sleeve second end includes a plurality of consecutive ridges to seal said sleeve second end to said another of the pipes. 6. The test fitting as in claim 5, wherein said sleeve is constructed of a durable rubber material. 7. The test fining as in claim 5, wherein: said sleeve is constructed of a durable rubber material; a metal outlet is molded in said sleeve about said hole, said outlet defining female threads; and said plug includes male threads complementary to said outlet female threads for selectively sealing said hole after said cord is withdrawn through said hole. 8. A test fitting for installation in a plumbing system comprising a plurality of pipes, said test fitting comprising: an annular sleeve having opposed first and second ends and an inner surface, said inner surface defining a hole and an open interior space, said sleeve including a ledge extending from said inner surface into said interior space; a cord having a first end removably positioned in said sleeve interior space and a second end extending through said hole for removing said cord through said hole, said cord first end forming a watertight spiral disc extending across said interior space to define a first area completely separated from a second area, an outer edge of said spiral disc being supported by said ledge; means for selectively sealing said hole after said cord is withdrawn through said hole; a sheathing encompassing said inner surface and defining a sheathing hole adjacent said inner surface hole, said sheathing including unattached and overlapping first and second ends distant from said sheathing hole; a first hose clamp adjacent said sleeve first end and outwardly adjacent said sheathing for attaching said sleeve first end to one of the pipes; and a second hose clamp adjacent said sleeve second end and outwardly adjacent said sheathing for attaching said sleeve second end to another of the pipes; wherein said first and second hose clamps include color indicia to visibly differentiate said test fitting from the remainder of the plumbing system. 9. The test fitting as in claim 8, wherein: said sleeve first end includes a plurality of consecutive ridges to seal said sleeve first end to said one of the pipes; said sleeve second end includes a plurality of consecutive ridges to seal said sleeve second end to said another of the pipes; said outer edge of said spiral disc is temporarily adhered to said ledge; said cord second portion meets said cord first portion at a center of said spiral disc; said cord includes a durable rubber material encasing a flexible wire; a tee handle is attached to an outer end of said cord second portion; and said spiral disc includes a spiral valley surrounding said flexible wire to ease said withdrawal of said cord through said hole.
