10 Irrigation leak

     10 fairway developed a wet spot couple of months ago.  We thought it was a valve since all the water was coming out of the valve box.  After digging it up we found out the valve was good.  Water was following the irrigation line.  We found the leak on a 8'' mainline tee.  This line comes directly from the pump station.  We had to order parts to fix the tee.  Our local distributor does not carry parts for anything larger than 6''.  The entire tee was covered with concrete about 12'' - 14'' thick.  That was the most concrete I have ever seen on any irrigation project.  To isolate the leak we had to turn off  3 valves.  This made it difficult to water turf on the back nine. Water had to come all the way from # 4 fairway past Clubhouse down 18 fairway back to 17.  The further you got away from 4 the weaker the pressure was.  Back down in 12 and 13 fairways we could not get fairways heads to run properly.  We could only run greens 1 station at a time.  We had the water off to the leak for 3 days.  2 days to install the new tee and 1 day for our concrete thrust block to cure. This was the biggest leak I have ever fixed.  I am glad this job is finished.
