Nightmare Resolved

[PurpHaze]

Take and pour concrete over a sprinkler (I remember it was a Toro 640), let it sit for a few years until it finally starts leaking and what do you have? In this case the water finally reached an electrical makeup box (Pic #1), found its way down conduit to a room 150' away (Pic #2; back left with door open) and came up inside the building through the electrical panel conduit (Pic #3). :dizzy:

They poured concrete over a head?

:laugh:

Were you lucky enough to be able to just cut and cap a lateral spur, or did the jackhammer have to come out?

If the jackhammer had come out I'd of taken additional pictures. We put the trencher down along the sidewalk and found the 1-1/2" lateral where it went under the sidewalk and capped it off. Site principal was quite impressed with our resources on this one. :)
