    I installed a small system on my own for a friend the other month. This is my documentation to him. Feel free to comment and b!itch, or take a chapter and learn something - apply it and create your own methods. My documentation at my real job is just about as detailed , just much much more streamlined.

    I personally think asbuilts are a waste of time and to most people they are greek. The only think I'm okay with is a vague map of valve box locations.. Anything else more detailed as a map .. What's the point? When a customer brings out there asbuilt and wants to show me a head... ' I swear the head is right here!!!' It's a waste of time to me. It doesn't help me save time at all. I have to stare at lines vs just getting things turned on my self.

    In any case, aside from a smart controller and soil tests.. I feel documenting is very important... which takes about 15 -30 minute to gather data and some time to write it all up. I wrote these up in a format I cant upload so I have to copy and paste. Of course the layout is going to be way different to what I wrote up- No underlines/ font size/ color changes/ bolds ect...

    Thats great documentation. I wish there'd be a lot more contractors to perform that step.

    Personally, I've started taking photos when we trench, lay pipe, dig valve boxes, etc. Especially where pipes cross and a couple of items run in the same trench, like mainline + conduit for wire.

    I'll post up photos of my latest endeavor soon.

    That's great information. I'm wondering if you do meter reads for your GPM for each zone or use published rates?

    Overall an excellent write-up and more useful to a homeowner than an as-built.

    Meter readings.

    a 2 min test will give you a accuraute result- having a remote is very handy. You can even do one min if you charge the line up first.
