The valve box for zones 1 & 2 is flooding with water every time the master valve is turned on.
I've only got it partially dug out, but it looks like when we installed it, there was a manifold made of two 4 inch tees, or maybe a tee and an elbow.
Anyway, it looks like the tee has a crack in it, so any time we're watering, the master valve is turned on and water is pouring out of that crack. It's probably not quite as bad as having another sprinkler head on, so I'm going to continue to water.
Is there anybody in the club who has experience with fixing this kind of thing?
I've dug down to the bottom of the valve box, but the lines to the sprinklers go through holes drilled in the box, so I'll have to cut a slot down to the bottom to lift the box off. The serial power/control lines go through holes in the end of the box, and I'll have to cut slots there, too.
All that I can see to do is reproduce that manifold, cut all the input and exit pipes, and put flanged fittings or unions on all the pipes that were cut. Once we cut that main line, though, we can't water again until it is fixed.
I'm really hoping someone with more experience will have some good suggestions.
It looks like there will be an awful lot of careful hand digging, so volunteers to help with that would be appreciated, too.
