- STEP 1: INSTALL COLD WATER SUPPLY FITTING -
Check and comply with local plumbing codes as you plan, then install a cold feed (supply) water fitting. The
fitting must provide a leak- tight connection to the RO 1/4" tubing (see Figure 8, page 8). A typical connection
using the included water supply fitting is shown in Figure 3A below. An optional connection, using standard
plumbing fittings (not included), is shown in Figure 3B.
Note: Codes in the state of Massachusetts require installation by a licensed plumbe_, and do not permit the use of a saddle
valve. For installation, use plumbing code 248-CMR of the Commonwealth of Massachusetts.
A. WATER SUPPLY FITTING
1. Close the house main water shutoff valve and open
faucets to drain water from the sink cold water pipe.
2. Remove nut that connects the cold water faucet to
cold water plumbing.
3. Use pipe joint compound or Teflon tape on cold water
faucet stud threads and on the mate threads of the water
supply fitting that connect to the cold water pipe.
B. OPTIONAL PIPE FITTINGS (compression type
shown)
Note: Be sure to turn off the water supply and open
a low faucet to drain the pipe.
Complying with plumbing codes, install a fitting on
the kitchen cold water pipe to adapt 1/4" ©D tubing.
A typical connection is shown in Figure 3B. If
threaded fittings are used, be sure to use pipe joint
compound or Teflon tape on outside threads.
4. Thread water supply fitting onto pipe and reconnect
nut to bottom of fitting.
