Feed Water Supply
Check and comply with local plumbing codes as you plan,
then install a cold feed water supply fitting. For new home installation using
standard plumbing fittings, see first two illustrations below. A typical
installation for existing homes using the saddle valve is shown in third
illustration below.
A. PREFERRED INSTALLATION
Turn off the cold water supply.
Complying with plumbing codes, install a fitting on the cold water pipe to
adapt 3 ⁄ 8
″
OD tubing. A typical connection is shown in illustrations at right
(parts not included). Make sure a water supply valve is used.

B. OPTIONAL HOME INSTALLATION Where codes permit
*For 1/2" OD or larger metal tubing only.
NOTE: Codes in the state of Massachusetts require installation by a licensed
plumber and do not permit the use of the saddle valve. For installation,
use plumbing code 248-CMR of the Commonwealth of Massachusetts.
Turn off the cold water supply and attach saddle valve as shown in
illustration at right.
DANGER: To protect yourself from serious injury or fatal shock, use
a battery-powered hand drill only to make the hole. DO NOT USE AN
ELECTRIC DRILL.
Close the water supply valve by turning the handle clockwise.
Open the main water supply valve and several house faucets to purge
air from the system. Close faucets when water runs smoothly. 3
