I'm selling my home and I've got an open house tomorrow. I've discovered a sprinkler pipe leak, apparently under a small brick patio. There's a diagram of the area posted under "Sprinkler Pipe Leak" in alt.binaries.pictures.misc . Can anyone tell me if there's a fast way to fix this without digging up the patio?
(The X in the diagram indicates a place where water bubbles up.)
Thanks.
