4.3. THE DRAIN
I. Connect a 13 mm hose to the drain of the control
valve (1); secure it by means of a clamp.
II. Run the drain hose to the sewerage system and
connect it to the stand pipe assuring sufficient air
gap. This drain line operates under pressure, so it
may be installed higher than the water softener.
III. Connect a 13 mm hose to the overflow elbow,
located at the back side of the water softener;
secure it by means of a clamp.
IV. Run the drain hose to the sewerage system and
connect it to the stand pipe assuring sufficient
air gap. This drain line does NOT operate under
pressure, so it may NOT be installed higher than
the water softener.
Notes:
• It is recommended the use of a stand pipe with
air trap.
• To prevent backflow from the sewerage system
into the water softener, always make sure to have
an air gap between the end of the drain hose and
the sewerage system itself; as a rule of thumb,
the air gap should be minimum 2x the diameter
of the drain hose.
• Always use separate drain hoses for the control
valve (evacuation of rinse water) and the softener
cabinet’s overflow.
• Lay-out the drain hoses in such a way that
pressure loss is minimized; avoid kinks and
unnecessary elevations.
• Make sure that the sewerage system is suitable
for the rinse water flow rate of the water softener.
