A.The first thing to connect after your (garden faucet - hose bibb) is a pressure regulator (#PRH). Then either install an inline strainer (#FIL75) or install both a brass Female-to-Female hose adapter and wye strainer (#DFILHC) (if you install the inline strainer you will not need the female-to-female adapter). Then the vacuum breaker (#DVB) and finally the adapter CSAW700 that goes from female hose threads to the pipe. Once you have done the "hard part" (ordered and then installed these parts in this order) the rest of the drip installation usually is very easy.
