Install Drain Adaptor
Running the drain tubing directly to a floor drain, sump, standpipe, laundry tub is preferred. See "Air
Gap Requirements"
section. This can also help eliminate noise in the faucet. However, if that is not
possible or practical, the drain adaptor (provided) installs in the sink drain pipe, always above or ahead
of the p-trap. The drain adaptor fits 1-1/2" sink drain pipe. Other drain pipe fittings, in addition to the
adaptor, may be needed. Locate so drain tubing from the faucet makes a straight run to the adaptor,
without dips, loops, low spots or kinks.
1.
Use a ferrule and nut to assemble the drain tubing connector to the drain adaptor. See Figure 4.
Turn the connector to about 45 ° from the 12:00 position, as shown (to 10:00 or 2:00 position as
needed). Tighten the nut securely.

2.
Carefully disassemble
the sink drain pipe and clean the tailpiece to assure a leak-tight fit.
3.
Install the drain adaptor onto the sink tailpiece, using a ferrule and nut. Snug the nut, but do not
tighten.
NOTE:
If needed, you can cut to shorten the unthreaded
end of the adaptor. Do not cut too
short or the adaptor will not make a leak-tight
seal with the connecting
fitting. See
Figure 5.
4.
Assemble
the p-trap to the drain adaptor, and other drain pipe fittings as required (check codes)
to complete the drain run.
5.
Tighten all connections,
but do not overtighten
and break plastic fittings.
