    I'm trying to put a list together of things that we've seen on sprinkler systems, that other companies have done to cut corners, and thus made the system sub par. I'm not looking for technical formulas for designing that people didn't follow.

    So more on the lines of:

    Zones stretched above available GPM or pressure available
    No slack in wire at valve box
    Non-greases wire connectors
    Retail or big box store parts
    Class instead of Schedule PVC for mainlines
    Cut off risers instead of swing pipe or swing joints - I know for some areas this is SOP though
    Screw type clamps
    No valve box - just bury the valves
    Cramming too many valves in one box to save a buck - ahem... no names thrown out
    Spacing heads too far apart
    Wrong style BFV because it is cheaper - I see lots of PVBs that should be RPs
    PVC coming out of BFV instead of copper

    I know there will be some things that are preferences - I know Mike likes 6" heads and stainless steel stems.

    That is SOP here. Rarely mainlines. Manifolds near the BFV.

    But I understand.

    Twisted wire used for poly pipe clamps. Non-stainless crimp cramps.

    Homemade relay addition to a 3-zone timer to allow it to operate 4 zones.

    3/4-inch insert coupling hammered into the end of a one-inch insert coupling, to make a reducer coupling.

    Seen it. I've also seen 1" poly fitting with the barbs sanded down to fit inside the off-sized Rain Jet pipe.

    AVB instead of PVB - but most of these are 20-40 years old
    System hooked to hose spigot for supply
    VAN spray nozzles used on the entire job when fixed nozzles could have been used
    Bonnet and/or poppet glued or caulked to get it to stop leaking - usually a homeowner though
    Electric, duct, or scotch tape instead of wire connectors
    Buckets or "tupperware"used for valve boxes

    PVC fittings plumbed directly onto intake and discharge of a pump.
    Lack of teflon.
    Pipe barely buried. I mean it does take work to bury it.
    Trenches not tamped.

    White PVC risers painted green.
    Five foot tall risers to clear shrubs.
    45's used as electrical sweeps.
    Both wire splices at valve shoved into one grease cap.
    PVC pipe glued into poly pipe.
    Pipe higher than top of head.
    Pipe so shallow you trip over it when walking through a yard.
    Pop-up stem stuck due to glue or primer in head.
    Damaged diaphragm and seat due to glue or primer in valve.
    Wiring run through trees rather than buried.
    White PVC pipe used as controller wire conduit.
    Top of valve higher than top of valve box.
    Using refurbished controllers. :p
