Arrived back to the home for water leaking out of the air gap weep hole of the Ro faucet. Client has had this problem in the pass. One tech discovered that the discharge drain going into the tubular was clogged, thus making the water come out of the weep hole. We arrived back today for the same issue. I disconnected the nut for the saddle on the tubular and the drain pipe was completely clogged again. I blew the debris out and the line is no back to normal. If water does keep coming out of the weep hole, either replacement of the saddle to a larger diameter, or replacement of the faucet is recommended. No 59$
