It is essential that a "backflow prevention device" be installed on any
sprinkler system, especially one that is equipped for chemical injection.
Failure to do so puts the water supply in your own home at risk and also the
community.

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
