6.6 Installing the Comfort valves
Do not use Teflon tape, pipe joint
compound or pipe dope on the valve
threads.
Tighten the flex hose connections, plus
1/4 turn with a wrench. Overtightening
the flex hose connections can result in
valve damage, causing the valve to
leak and/or localized water damage.
When making pipe connections, be
sure to follow the pipe manufacturer’s
recommendations and all code
requirements for pipe material.
By plumbing convention, the hot water
is on the left side and the cold water on
the right side, when looking at the sink.
Your pipes may be different.
6.6.1 Valve location
For the greatest effect, the comfort valve must be
located at a faucet with the greatest pipe distance
from the hot-water heater. If a household consists
of more that one hot-water piping string, a comfort
valve must be mounted in each string.
6.6.2 Disconnecting the risers
1. Close both the hot- and cold-water angle stop
valves below the sink.
