发帖数: 232 | 1 我家的系统是Toro 570 Fixed Srpay有5个valve group, 其中一组是埋在草地边沿的,
正常工作的时候都是pop-up然后喷水, 近来我发现无论是设成自动还是手动打开阀门,
这一组所有的喷头都不再pop-up,但有水从旁边流出. 可能是有一段时间不用了(加州雨
季), 有些喷头还被埋在了土里, 我把它们扒拉出来, 清理掉泥土和草根,还是没用,那
些个喷头杆子倒是可以拉出来然后自己再缩回去.
我上网查了一下,可能的原因:
1. Not enough water pressure to run the zone, Split the zone in two
2. Master or zone valves not completely open. Open counterclockwise
3. Flow control on zone valve not fully open. Open flow control
4. Debris between sprinkler riser and riser seal
1和2基本可以排除,因为它跟其它几个group是用的同 | g*****9
发帖数: 4125 | 2 There is a little tool to take the head out and put a new one in. Every year
a few will always go bad in my set up, So I just buy a case and replace the
bad one in spring, I blieve it only cost a few dollars per head.

发帖数: 180 | 3 Seems to be not enough water pressure. The reason could be 1, 2, 3. Check
the valve to see if it is truly opened when the system is turned on.
