•
Before starting installation work close the under sink hot and cold water riser shut-off valves
and open the hot and cold water faucets/taps to relieve the water pressure. Close the water
faucets/taps.
NOTICE:
In some older homes, the riser shut-off valves may be difficult to shut off completely, or maybe
it is necessary to turn the valves into a different orientation. If this is the case shut the water off at
the main water inlet valve to the house.
