Two possibilities, one is that dirt got in the valve from your other
repair, not allowing the valve to fully close. Try cycling that station a
couple of times, or better yet, take a head off that station and purge
the line. If that doesn't work, then the spring in the valve is probably
weak. I had the same problem and had to replace the valve. A lot of
digging and hard work. They do sell the internals for valves, but mine is
20 years old, and they didn't sell them any more.
Good luck.
