    I was impressed by the cable-TV nail-it clamps that worked with masonry - just the size for spaghetti tubing

    Those were exactly what I was picturing in my head originally the cable mounts

    You can drill through the footing and push a 3/4 in galv. pipe through the footing with a backhoe or mini-ex.

    The pipe can be located and the slab core drilled over the pipe.

    The pipe can be cleared of soil and drip pvshed out from the slab. The metal pipe can then be removed and you are in business.

    If more than 20 ft or shorter lengths are used due to space constraints, I use gas pipe thread protectors rather than couplings because they are smaller and smooth.

    Google BURKE water plug or anti hydro products.

    What ive done when ive needed to get 1/4" tubing up into the pot from below is take a piece of swingpipe and coil it tightly and tape it. Run the 1/4" line through the inside of the funny pipe and up into the pot. I guess then you still have the issue of getting to the pot from the wall.

    1/4 inch line is a PITA I hate that kind of work but I'm seeing more of it :(.. I hate it cause my boss usually piggy backs it off a rotor zone..

    Is it possible to release water from up above out of eye sight?

    You'd think modern technology could create a self-propelled garden gnome with a watering can to deal with stray pots.

    Kinda like the robot vacuum? Call it ROBO-GNOME :)

    Funny how we can put men on the moon and yet fail to provide a path for irrigation in construction.

    Last year I did a job where they wanted pots on the four corners of the pool. We ran 1/2" poly under the slab before it was pored. We had one end come up in the expansion joint at the pool coping and the other ran out into the lawn to where we could access it. We then ran the 1/4" inside the 1/2" poly. It worked great.

    I would expect no less from you GM, but most builders are either too cheap or lack the insight to think beyond their next paycheck.

    There is a builder in our area that requires 4 - 1.5 sleeves buried 18 in deep under driveways and 1 sleeve for every 20 feet of sidewalk.

    This guy lives to build and it shows in all aspects of his work. :)

    There's always a way to get access under the cement, it just takes money. If it needs to be clean, the pots are pretty "permanent" and they budget allows, you should core-drill it and run a horizontal bore (directional drill) to get your pipe in to the cores. It's going to be difficult and expensive but it will be "right."

    Otherwise, I'd probably tell them to have the maid water the plants, anything you run on the surface is going to look like an afterthought, no matter how neatly done, and be a trip hazard.
