Greetings,
I am having trouble with my eight-year old Rainbird system. I have no idea when the problem began because the system runs in the early morning hours. The last time I checked it was before the holiday season (Thanksgiving time) and it properly functioned at that time.
Facts:
1. Four (4) zone Rainbird system.
2. Zones 1, 2 and 3 are the problem. When selecting any one of those three zones, only a small amount of water trickles through a few of the heads. I checked for broken heads ('gushers') and did not find any.
3. The pump strains (not a cavitation sound) when zones 1-3 are selected.
4. Zone 4 works normal with full pressure. All sprinkler heads in zone 4 pump as expected.
5. Normal sounding pump on zone 4.
Looking at a previous post, I am suspicious of the valves. One previous post had a Rainbird video but the video referenced a reverse flow valve system. I have no idea what that is.
Any suggestions are greatly appreciated.
