I have built some of the components and will post pictures as I get a chance.
I will be using a high pressure low volume dosing pump to inject concentrated chemicals into the main sprinkler line when the system is running. The concentrated chemical tank will be in the basement and I have run my dosing line and valve box outside where the dosing tip will sit. I am using a relay that is fired off of the irrigation controller to power my dosing pump. I will run the injector system for a short cycle with first insecticide concentration to get rid of the grubs or main food source, then I will continue with a gopher repellant which is a mixture of castor oil, and some essential oils that should dirve them out of the yard and keep them away. Finally I can inject liquid fertlizer so I can maintain the area.
