1. A fluid flushing system comprising:
a sampling port comprising a sampling conduit configured to dispense a sample of a fluid in the fluid flushing assembly;
a valve configurable in an open valve configuration, wherein the fluid is permitted to flow through the fluid flushing system, and a closed valve configuration, wherein the fluid is prohibited from flowing through the fluid flushing system;
a backflow preventer disposed between the sampling port and the valve, the backflow preventer configured to allow the fluid to flow in a first direction through the fluid flushing system towards the valve and to prevent the fluid from flowing in an opposite second direction through the fluid flushing system towards the sampling port;
a housing comprising a base and defining an interior cavity, wherein the sampling port, the valve, and the backflow preventer are oriented within the housing; and
an inlet pathway configured to route the fluid from a fluid system into the fluid flushing system and an outlet pathway configured to route the fluid out of the fluid flushing system;
wherein:
the sampling port is disposed between the inlet pathway and the backflow preventer;
the valve is disposed between the backflow preventer and the outlet pathway;
the inlet pathway comprises an inlet conduit extending into the interior cavity through an inlet opening in the base; and
the outlet pathway comprises an outlet conduit extending into the interior cavity through an outlet opening in the base.
