The solution was a 2"coupler. It was a little difficult to install because the two pipes weren't perfectly aligned. I eventually was able to get the threads started on both ends. With an 18" pipe wrench and a pair of channel locks tightened both ends as tight as I could get them.
I turned on the water main and it didn't leak. I turned on the outside water spigots, then worked my way inside, getting the air out of the lines. I went back out to check the pipe and the hole was still dry. I did another check 2 hours later, and the coupler was leaking. Close inspection showed that I was able to tightened one side 1/4 inch more than the other. I needed a bigger wrench!
I turned off the water, went to Home Depot and purchased a 24" pipe wrench. With better tools, I was able to tightened both ends to the point where the threads were not visible. Turned on the water again, no leak!
Saturday it was still fine, so I scooped all the water out of the hole. Later I filled it in with dirt, packing the dirt as I filled it up. Then I drove over it many times with the Yukon. Sunday it rained, but the dirt remained firm. I will eventually seal it with black top.
The next challenge is to destroy the roots that are coming across the road, because it will happen again in another location. There are spots where the asphalt is being pushed up. Pouring Roundup or Remuda have been recommended.
