1. A whole-home pressure relief system for relieving pressure from a home's plumbing system, the whole-home pressure relief system comprising:
a main body having an inlet end, an outlet end, and a hollow interior;
inlet threads extending into an interior wall of the inlet end, the inlet end and inlet threads configured to removably engage with male threads on a conventional hose bib;
a flow restrictor channel extending from a bottom end of the inlet end toward a central portion of the main body, wherein the flow restrictor channel has a diameter smaller than a diameter of the inlet end;
a valve chamber within the interior of the main body, the valve chamber in fluid communication with the flow restrictor, wherein the valve chamber is configured to accept a pressure relief valve such that a valve inlet is in fluid communication with the flow restrictor;
a threaded channel extending between the flow restrictor channel and the valve chamber, wherein the threaded channel is configured to removably engage with a threaded end of the pressure relief valve;
outlet threads extending into an interior wall of the outlet end; and a sight cup attached to the outlet end, the sight cup being transparent and configured to provide for visualization of water exiting the outlet end.
