Scott our system does not have a ballast tank, the flow well is plumbed directly to the pump and the independent hydraulic valve is plumbed just on the output side of the pump prior to the current manual indexing valve so that the flow well will not free flow to and out of the sprinkler heads while not operating. I'm thinking with the new solenoid valves there will not be a need for the hydraulic valve because the solenoid valves (in my mind) will have a positive shutoff while not in operation?
