An externally engaging test barrier for use in testing hydrostatic pressure in a plumbing system having two abutting plumbing components. The test barrier includes a barrier body having a first face, a second face, and at least one peripheral engagement for engaging an external surface of at least one of the two abutting plumbing components to hold the barrier body in position across an end of at least one of the two abutting plumbing components. The peripheral engagement extends perpendicularly from the first face or the second face. A removable portion of the barrier body is defined by a frangible connection. The peripheral engagement of the barrier body is incapable of sealing the plumbing system during a hydrostatic pressure test, unless used in combination with a pipe coupling that forms an overlying sealing sleeve.

1. In combination: an externally engaging test barrier for use in testing hydrostatic pressure in a plumbing system, the plumbing system comprising two abutting plumbing components, the externally engaging test barrier comprising: a barrier body having a first face, a second face, at least one peripheral lip extending perpendicularly from at least one of the first face and the second face, and a removable portion of the barrier body defined by a frangible connection;the diameter of the peripheral lip being sized to engage an external surface of one of the two abutting plumbing components; anda coupling comprising: a resilient sleeve sized to overlie the peripheral lip of the barrier body and engage each of the two abutting plumbing components, the resilient coupling sleeve securing and sealing the peripheral lip against the one of the two abutting plumbing components under a predetermined hydrostatic pressure of a hydrostatic pressure test. 2. The combination of claim 1, wherein the coupling is rubber and the externally engaging test barrier is a non-elastic material. 3. The combination of claim 1, wherein the resilient sleeve comprises an integral spacer element for inserting between the two abutting plumbing components. 4. The combination of claim 1, further comprising an annular sealing surface disposed between the peripheral lip and the removable barrier, the annular sealing surface engaging the one of the two abutting plumbing components or an integral spacer element of the resilient sleeve. 5. The combination of claim 4, wherein the peripheral lip extends perpendicularly opposite from the opposite side as the annular sealing surface. 6. The combination of claim 1, wherein the peripheral lip engages the plumbing component under pressure. 7. The combination of claim 1, wherein the peripheral lip engages the plumbing component opposite the plumbing component under pressure. 8. The combination of claim 1, wherein the peripheral lip comprises a broken engagement surface. 9. An externally engaging test barrier for use in testing hydrostatic pressure in a plumbing system, the plumbing system comprising two abutting plumbing components, the externally engaging test barrier comprising: a barrier body having a first face, a second face, at least one peripheral engagement for engaging an external surface of at least one of the two abutting plumbing components to hold the barrier body in position across an end of at least one of the two abutting plumbing components, the peripheral engagement extending perpendicularly from the first face or the second face, a removable portion of the barrier body being defined by a frangible connection;the peripheral engagement of the barrier body being incapable of sealing the plumbing system during a hydrostatic pressure test unless used in combination with a pipe coupling that forms an overlying sealing sleeve. 10. A two component test barrier assembly for testing hydrostatic pressure, comprising: a cap for covering an end of a pipe, the cap having a body with a peripheral sidewall and an end wall, the end wall having a removable portion connected to a remainder of the body by a frangible connection, with a pull tab secured to the removable portion to facilitate removal by pulling on the pull tab to sever the frangible connection; anda pipe coupling that is sized to overlie the pipe, wherein the pipe coupling has a circumferential spacer element that forms a portion of a labyrinth seal with the cap.
