8) Troubleshooting
Water leaks from threaded connection:
Tighten fittings or hex nut until leak stops. If leaks persist, shut off water at the cold water
valve, remove threaded fittings, reapply PTFE tape around the fitting to the left (counter-
clockwise), and screw back into head assembly or saddle valve.
Water leaks at quick connect fittings:
Push tubing in as far as it will go. If leaking continues, shut off water at the cold water valve
and remove water line by pushing in on the connector collet while pulling the tubing away.
Inspect tubing for cracks. If tubing is cracked, simply cut that portion away and re-insert
tubing into quick connect fitting (see Figure 1, Page 8).
Water does not flow from the drinking water system faucet:
