We determine the value of the $\omega -\rho- \pi$ mesons coupling ($g_{\omega\rho\pi} $), in the context of the vector meson dominance model, from radiative decays, the $\omega \rightarrow 3\pi$ decay width and the $e^+e^- \rightarrow 3\pi$ cross section. For the last two observables we consider the presence of a contact term as mimicked by a heavier resonance ($\rho'(1450)$) and find its magnitude to be close to other approaches. A weighted average of the results from the set of observables yields $g_{\omega\rho\pi} =13.8 \pm 0.1$ ($g_{\omega\rho\pi} =11.6 \pm 0.2$) without (with) contact term. Improved measurements of these observables and the $\rho'(1450)$ meson parameters are needed to give a definite answer on the pertinence of the inclusion of this last one in the considered processes.
