    Here's an example of what can occur when a proper thrust block is not poured. This was a job by an outside contractor at a school site where we're switching from well pump (pump has been shot for years) to city water and installing a Watertronics booster pump for the irrigation.

    How long did it run before someone shut it off?

    It's a 4" line. By using the last picture... it run's from off-camera left across the lawn area from the domestic POC/new irrigation backflow to the point of connecting with the the new Watertronics unit. It then goes from the unit into the old main line... bypassing the old pump/tank that's located behind the stucco wall.

    I believe it ran for about four hours. The "on-call district plumber" received a phone call from the fire department at 3:30 AM and firemen were able to turn off the backflow for us after being advised which of the two in the enclosure it was.

    Hole was full of water when I was there the next day. I'm going out that way to a Ewing BBQ tomorrow so I'll drop by and see if it's been repaired yet and maybe take some pics then.

    oooo a 4" main freeflowing for 4 hours....that ends up working out to a boat load of water.

    Forgot to follow up with pics on this sitch but by the time I got out there the contractors had repaired their work and poured thrust blocks. Since their new line let loose near the PVC/galvanized transition they also decised it might be prudent to pour one at the transition after the backflow. Here's a couple of pics of that.
