So I mentioned in another post that I am not impressed with whoever installed my sprinkler system. I just found another issue that I’m not sure I’m going to be able to do much with without physically adding or moving sprinkler heads. One of my side yards is about 15 feet wide with a slight slope away from the house. Unfortunately the only sprinkler heads for this zone are spray nozzles at the bottom of the slope.
I did my catch cup test today and at the bottom of the slope near the spray heads I got about 1.2 inches per hour. I’m the middle of the slope I was seeing .76 inches per hour and at the top of the slope some areas got almost nothing and others got some water, but were under .5 inches per hour.
If I try to water the zone based on the needs of the grass at the top I’m going to seriously overwater the bottom. Not to mention that the slope will make it worse as water runs down.
Do I have any options here other than adding more heads at the top of the slope or moving the existing heads to the top?
