Step 5: Flush faucet
Pull the hose assembly out of the spout and
remove the spray head by unscrewing it from
the hose in a counterclockwise direction. Be
sure to hold the end of the hose down into
the sink and turn the faucet on to the warm
position where it mixes hot and cold water.
Flush the water lines for one minute. This
Fushesaway any debris that could cause
damage to internal parts. Check for leaks.
Re-tighten any connections if necessary, but
do not overtighten. Reinstall the spray head
by hand tightening it back onto the spray
hose.
After installation is completed, turn on the
hot and cold water supplies. Check for leaks.
