Some pics of a repair we did yesterday. Turned the backflow off several days ago to allow area to dry up but when we started digging up by the valve (where the water was surfacing) there was no leak evidence. Had to turn the backflow on to follow the leak and found it 8' upstream at the tee. All but 1/4" of the pipe had pushed out of the tee. Investigated downstream by the valve and found that the pipe in the bell joint and at the valve tee also had not been pushed in all the way during the original install so we replaced everything past it. The soil is highly alkali here and turns to mush when water mixes with it. Backfilled with sand and we'll haul the other stuff away today.
