A hose end backflow preventer should always be connected directly to the spigot or faucet, before the hose, unless you are using a hose end timer. Ehn using a hose end timer, connect the hose end backflow preventer to the base of the hose end timer, before the hose. For faucet installation only. Do not install on main line.
A backflow preventer keeps contaminated water from re-entering your household water system, and should always be used when applying fertilizer.
