I had a leak at the main shutoff valve coming into the house. It just seemed to be leaking around the stem, but it was hard to tell. So I called the city and $60 (this blows my mind) later they shut off my water. I went to Home Depot to try and find a replacement stem, which was a futile effort. So I ended up buying some new stem packing. This seems to have solved the problem, as another $60 later I'm leak free. In hind sight, tightening the packing nut might have solved my problem. But the Flax/graphite combo in the packing nut seemed pretty dried out.
I'd like to have one of these on hand for future disasters, not to mention my own T-Wrench (probably illegal). Given the speed with which the city reacted to my original call, I'd hate to have water gushing into my basement. (Finally the question) The valve is actually in an elbow that is threaded on one end and slip on the other. The stem threads into the top of the elbow. It is probably an 1.25" where it screws into the valve and only has about 1/8" of thread. The valve is about 30 years old. What is this type of valve called and who might the manufacturer be?
