Dug up site #12 had to remove the traffic control sign. We found an old valve when we removed the sign, it was a 8" gate valve that did not work. The county said to replace it, so we replaced a 8"x3" tee, 10' 7" piece of 8" pipe, installed one 8" gate valve with 2 hymax coupling, one 3" gate valve, one 3"x2" cap, and one 2" compression coupling. The top of pipe was 5' 6" deep. We had to dig back an extra 15' because the pipe was too big for the hymax couplings. We then had to dig back to the next joint where the hymax would fit. One of the hymax's were leaking, it wouldn't seal right. So, we had to cut the 8" PVC pipe and put in one 8" sleeve and another romac coupling. Then we back field and compacted the hole. Three men dressed up the sites while we poured the valve pads.
