  The decays omega -> 2pi^+ 2pi^- pi^0 and omega -> pi^+ pi^- 3pi^0 are
reconsidered in the hidden local symmetry approach (HLS) added with the
anomalous terms. The decay amplitudes are analyzed in detail, paying the
special attention to the Adler condition of vanishing the whole amplitude at
vanishing momentum of any final pion. Combining the Okubo-Zweig-Iizuka (OZI)
rule applied to the five pion final state, with the Adler condition, we
calculate also the phi -> 2pi^+ 2pi^-pi^0 and phi -> pi^+ pi^- 3pi^0 decay
amplitudes. The partial widths of the above decays are evaluated, and the
excitation curves in e^+e^- annihilation are obtained, assuming reasonable
particular relations among the parameters characterizing the anomalous terms of
the HLS Lagrangian. The evaluated branching ratios B(phi -> pi^+ pi^-
3pi^0)~2x10^{-7} and B(phi -> 2pi^+ 2pi^- pi^0)~7x10^{-7} are such that with
the luminosity L=500 pb^{-1} attained at DAFNE phi factory, one may already
possess about 1685 events of the decays phi -> 5pi.
