  We perform a global analysis of the low-energy phenomenology of the minimal
left-right symmetric model (mLRSM) with parity symmetry. We match the mLRSM to
the Standard Model Effective Field Theory Lagrangian at the left-right-symmetry
breaking scale and perform a comprehensive fit to low-energy data including
mesonic, neutron, and nuclear $\beta$-decay processes, $\Delta F=1$ and $\Delta
F=2$ CP-even and -odd processes in the bottom and strange sectors, and electric
dipole moments (EDMs) of nucleons, nuclei, and atoms. We fit the
Cabibbo-Kobayashi-Maskawa and mLRSM parameters simultaneously and determine a
lower bound on the mass of the right-handed $W_R$ boson. In models where a
Peccei-Quinn mechanism provides a solution to the strong CP problem, we obtain
$M_{W_R} \gtrsim 5.5$ TeV at $95\%$ C.L. which can be significantly improved
with next-generation EDM experiments. In the $P$-symmetric mLRSM without a
Peccei-Quinn mechanism we obtain a more stringent constraint $M_{W_R} \gtrsim
17$ TeV at $95\%$ C.L., which is difficult to improve with low-energy
measurements alone. In all cases, the additional scalar fields of the mLRSM are
required to be a few times heavier than the right-handed gauge bosons. We
consider a recent discrepancy in tests of first-row unitarity of the CKM
matrix. We find that, while TeV-scale $W_R$ bosons can alleviate some of the
tension found in the $V_{ud,us}$ determinations, a solution to the discrepancy
is disfavored when taking into account other low-energy observables within the
mLRSM.
