Replaced an old champion globe valve today from a commercial property. The system is around 20 years old. Someone updated the wiring on it more recently, but these valves are pretty ancient. Two 1.5" globe valves, the one on the bottom was the problem one. Bad Valve removed, I spun it out of the mainline tee so I wouldn't have to redo it. The old valve was threaded into the mainline using a galvanized nipple (into PVC!) I'm surprised this has lasted so long. I spun a new SCH 80 nipple into the tee. New rainbird valve plumbed in. I usually use a SCH 80 nipple instead of the male adapter, but I didn't have a TOE one on my truck in the right length. Also, the picture makes things not look square, but they are square, its just that my camera was tilted. Thats dirt on the two 90's too, not spilled primer. I rotated the valve because it would be rubbing the other one if they were set opposing like the old one and this configuration let me avoid using a repair fitting. All cleaned up. Total time was just a hair over an hour.
