A distribution station includes an adjustable feed network that connects first and second pumps with first and second manifolds. The network is switchable between first and second configurations. In the first configuration a first pump is fluidly connected with the first manifold and fluidly disconnected from the second manifold. Concurrently, the second pump is fluidly connected to the second manifold and is fluidly disconnected from the first manifold. In the second configuration the first pump is fluidly connected with the second manifold and fluidly disconnected from the first manifold, and the second pump is fluidly disconnected from the first and second manifolds.
