I have just had a brand new Rainbird sprinkler system professional installed. The water is pulled by a pump from a spring fed large pond. There are 9 zones with only 3 sprinkler head per zone. The very next day and the first time I had it on automatic timing I noticed the sprinkle heads in Zone 7 hardly working.i.e., a very low pressure. I switched it off and restarted in that same zone manually and the pressure was fine. The next day the exact same thing happened in Zone 6. I have had the company out but they cannot find anything wrong with it. The service guy said it must be some dirt in the system that keeps another zone on that causes the other zone pressure to be so low. I do check and there are no other zones on. Its as though the pump gets tired and does not pump out as much water. once it has been on for a while? If I turn the pump off and restart it the pressure is then OK. This morning the pressure was so low that I had to pull up the head myself and then the water came through, but still as a low pressure. The pump is obviously working and I did check to see if it is maintaining its prime and it is. But it is unable to maintain the pressure throughout all the zones. ( I have noticed the problem on zone 6,7 and 8). I then have to do it manually. The problem is only when the system is on automatic and the pump as been on a long time, the pressure drops. Any help would be most appreciated.
The pump is a Berkley ( on the land not submerged) 1HP, KW.76 , V115/230, RPM 3450, Hz 60, the only other number on the pump is 10HN
Can pumps get tired?
Thanks so much
