If a backflow preventer is part of the faucet (new houses) do not install any other
backflow preventer to the faucet. If backflow preventers are part of your city code
and you have purchased a unit as part of your drip system, install the device on the
downstream side of the RBC 7000 (Figure 6 and 6a).
It is best to include a filter on a drip system. The filter cleans small particles out of
the water that would otherwise clog the drippers. The filters can also automatically
apply fertilizer through a drip system (Figure 7 and 8).
