Urgent - Can't get valve closed
I posted earlier about some older hydro rain valves. On one of the valves that was not working I mannually turned it on and now it wont shut off, I have no way of shutting of the sprinklers without shutting down water to the entire house.
I have pulled the bleeder rod several times and let water spray up into the air but it wont shut off. Any instant advise would be greatly appreciated.
