Here in Fl indexing valves (KRain, Fimco, etc.) are commonly used in conjunction with lawn pumps for home systems. With the shortage of rain, well levels are getting lower resulting in a drop of pump output pressure so the indexers are not as reliable as they were when originally installed. I need to convert an existing Fimco indexer to electric valves (and install a pump relay and controller). To simplify the piping, I'm considering leaving the Fimco manifold in place (after removing the internal rotary indexer) and just installing the valves below ground level in the distribution lines. Anybody ever taken this approach? Can I expect a pressure loss by running the pump output through the empty Fimco valve body? Comments?
