If pissing on the fire were enough I'd be a staunch proponent. Alas, it is not. That said, the simpler the better. The pump on the pumper will always be more reliable than the one in place unless the owner happens to have his own pump mechanic checking it constantly. An experienced pump operator will always be better than an unmanned machine that just puts out and needs to be regulated by high maintenance PRVs. I see no need for auto in low rise if the pressure is adequate for the sprinks. KISS.
