    New problem at newer high school turned up this week. Main line leak under concrete and no way to isolate it because isolation valves were left out of looped system. Backflow had to be shut down which kills all irrigation to entire site.

    Picture #1: This is where water came gushing out but the leak is up under the concrete. But how far?

    Picture #2: Demolition starts. Leo and Hogie checking out the rebar in the concrete.

    Picture #3: Leo guiding Hogie into place.

    Picture #4: Different angle of Leo guiding Hogie into place.

    Picture #5: Danny cutting out rebar so I can dig a pot hole and see what the problem is.

    Picture #6: Leak still further back up under the concrete.

    Picture #7: Two 1" lines feeding a 1-1/2" line. Contractor notorious for this crap.

    Picture #8: Connection to 1-1/2" line.

    Picture #9: 2" line blown out.

    Picture #10: Closeup of blowout.

    Concrete will have to be saw cut on Monday so we can demo back further in order to make the repairs.

    I'd say that blew out because of improper glueing.

    in pic #9, was that black pipe a swing joint to a head??

    I swear, id like to hang out with you guys for a week to see some fun repairs. (not that i dont see my share lol)

    Looks like the pipes were installed then someone came back later on and had to move some things,
    that doesnt look good having elbows and crap under the middle of a concrete slab, not in a sleeve

    I'm with Sheshovel. Kinda looks like someone missed the primer, or maybe didn't let things set up long enough.

    Next time Hayesy ol' boy drive a screw down through the fitting and the pipe to hold your joints together!

    Yes... it's a Marlex on an abandoned swing joint. The area where the isolation valve is used to be grass until about 1-1/2 years ago. A new building was constructed and this area became sidewalk.

    It'd be cool but after a week they tend to blend into each other. :laugh:

    No sleeves at all on this site so I'm sure there will be even more problems.

    Definitely glue joint failure. I'll know more when I can get to it and cut it out.

    Not mine... famous local contractor. :dizzy:
