SECTION3 STEP BY STE P G UIDES TO INSTALL
D. CONNECT VALVE AND SALT TANK DRAINS
_1_ CONNECT THE VALVE DRAIN HOSE
Cut an appropriate length of 3/8" drain tubing
(20 ft. roll included) and attach one end to the
drain fitting (FIG. 12). Put the other end of the
hose over a floor drain, into a laundry tub,
standpipe, or other suitable drain. Check your
local codes.
Leave an air gap of about 1-1 / 2" between the end
of the hose and the drain. This gap is needed so you
don't get a back-flow of sewer water into the soften-
er. Do not put the end of the hose into the drain or
connect without the air gap.
Place and support the hose so it does not kink or
have sharp bends. So water pressure does not cause
the hose to "whip", tie or wire it in place. Do not
pinch the hose shut. The softener will not work if
this drain hose is pinched, plugged, closed or re-
stricted in any way.
Keep the hose lower than the drain fitting. (In
some homes, to get to a drain you must raise the
hose and run it over-head. If you need an overhead
drain, do not raise the hose more than 8' above the
floor. A copper drain tube is best to use.)
COPPER DRAIN TUBE: The plumbing codes
where you live may say that you must use a copper
valve drain tube. A copper tube is also best to use for
an over-head drain. Use a copper drain tube if the
softener is installed outside, or in the sunlight. Heat
from the sun makes many kinds of rubber or plastic
hose to soften, flatten and close up.
To adapt a copper drain tube to the softener, buy a
compression fitting (1/4 NPT x 1/2 in. minimum
tube) and tubing from your local hardware store.
