James,
Let me clarify myself. On my water supply system, our automated lawn watering system is split off at the meter. My hose bibs are indeed part of the house feed line.
If you are drawing water for the EarthTainers from your outdoor sprinkler system, then my observation stands as above. If however, you are going to run a "Y" connector off your hose bib, it *may* be down-line of your home filtering system.
