    Here's what we replaced from our recent well-drilling thread: Fimco-Meister's nemesis and nickname inspirer:

    Why didn't you just replace the cap? Was there more damage than just that crack?

    Barb B (bblawncare) this link awhile back: http://www.fimcomfg.com/

    Have no idea if there was more damage, we lit up system and water sprayed everywhere out of crack. IMHO, K-Rain better product than Fimco, there is a better margin for replacing the entire indexer than just the part, plus I have no idea where to find Fimco parts.

    What isn't logical, use of indexer or way it operates?

    Think of it like a six-shooter, pull the trigger (fire the "solenoid") and the barrel turns firing a bullet (a zone). Pull trigger again, barrel turns and the next bullet/zone fires.

    One water inlet, but 6 or so water outlets to the zones.

    Water flows in the inlet pushing the stem and disk down. The disk closes off all zones allowing water to flow into one zone. As the city water valve closes or pump shuts off, the spring loaded stem pushes the disk back up. As it moves up, the cam (under that cracked cap) turns the stem and disk to the next zone.
    You can easily change cams to add a zone and glue another leg into the corresponding outlet.
    The downfalls: a little less precise control of time. There has to be ample time for the stem and disk to push the water out in order to change zones. Most allow 5-15 mins to avoid running the same zone over and over. The other thing is that in order to test a specific zone, you have to run through all the zones before getting to the one you want.
    The indexing valve has ALWAYS cost less to install...especially back when it was created and electric valves were an arm and a leg. Now with the price of copper constantly climbing....contractors have been using them more and more. A lot of wastewater contractors use them in their system b/c the valve doesn't care about effluent/dirty water.
    Very simple to troubleshoot if issues arise.
    Elevation is tricky with an indexer. If water is backing into the index valve, it won't allow the stem and disk to do its thing. Most use CV's to fix this. I've never heard of anyone winterizing a indexing system though.
    I believe the owner of Fimco once worked with or for the Kah's back in the beginning.
