1. A system, comprising:
a first conduit operably coupled between a suction manifold and a first fracturing pump, wherein the first conduit includes a first valve;
a second conduit operably coupled between the first fracturing pump and a discharge manifold;
a third conduit operably coupled between the first conduit and a fluid source;
a first configuration in which:
the first valve is or remains in a state that permits communication of hydraulic fracturing fluid from the suction manifold to the first fracturing pump via the first conduit; and
the hydraulic fracturing fluid is communicated from the suction manifold to the first fracturing pump via the first conduit, including the first valve, and from the first fracturing pump to the discharge manifold via the second conduit;
and
a second configuration in which:
the first valve is or remains in a state that prevents communication of the hydraulic fracturing fluid from the suction manifold to the first fracturing pump via the first conduit; and
another fluid is communicated from the fluid source to the third conduit operably coupled between the first conduit and the fluid source, from the third conduit to the first fracturing pump via the first conduit, and from the first fracturing pump to the second conduit.
