Patent ID: 8646314

Claim:
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; and a 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.
