I Need Help Please
I need help please. I have a 4 zone Rainbird system with 1 1/2 hp submersible pump in the river. The system is 10 years old but the pump is new. When pump was installed several weeks ago, everything worked well for a time. Now zone 1, furthest from the river, is not working. Zone 1 also has a new valve, just installed. When zone 1 starts, water gets to the rotors initially, and they start spraying, but then the spray fizzles out, and they continue with either a very weak spray or just bubbling. When the water is going through the pipe at the zone 1 valve, it makes loud gurgling noises like the flow is not consistent. None of the other valves make that sound. The pressure at the other 3 zones is really good, and it was really good at zone 1 when the new pump was installed. Any idea?
