Hi all,
Posted this in home repair before I found this group.

I've been trying to figuare out a way to attach a weed sprayer or create
some sort of attacment to my Sprinkler system.

Here's a rough idea:

----backflow preventer---weedkiller---Sprinkler system
I've taken apart several of the bottle spayers and it seems all I need is a
very small tube.
The bottle needs to be placed inline so that the water pressure would pull
solution through the tube and into the sprinkler system. I think I'll have
to have a pin size hole just so I'll only use a small amount of solution
during each watering.

Anyone done anything like this?
What did you use?
Can you provide a material list?

Thanks in advance
Steve J
