CONNECT AND RUN THE VALVE
DRAIN HOSE
(CONT.)
• Elevating the drain hose may cause back
pressure that could reduce the brine draw during
recharge. If raising the drain line overhead is
required to get to the drain point, measure the
inlet water pressure to the softener first. For inlet
pressures between 20 and 50 psi, do not raise
higher than 8
′ above the floor. For inlet pressure
above 50 psi, the drain line may be raised to a
maximum height of 14
′.
CONNECTING A RIGID VALVE DRAIN TUBE
To adapt a copper drain tube to the softener, use
a hacksaw to cut the barbed end from the drain
fitting as shown. Rotate the drain fitting so the
cutting blade clears the valve housing to prevent
damage to valve
. Buy a compression fitting (1/4
″
female pipe thread x 1/2
″ O.D. tube) and needed
tubing from your local hardware store.

INSTALL THE BRINE TANK
OVERFLOW FITTINGS AND HOSE
• Insert the rubber grommet into the 3/4
″ diameter
hole in the brine tank sidewall as shown.
• Push the end of the hose adapter elbow into the
grommet as shown.
• Attach a length of hose (use remaining hose from
Step 4) to the hose adapter elbow. Use a hose
clamp to hold it in place.
• Locate the other end of the hose at the drain
point. DO NOT ELEVATE this hose higher than the
elbow on the brine tank.
IMPORTANT: DO NOT TEE OVERFLOW HOSE TO
VALVE DRAIN HOSE.
NOTE: This drain is for safety only. If the cabinet
(brine tank) should over-fill with water, the excess is
carried to the drain.
