DRAIN CONNECTION GENERAL GUIDE
NOTE: Do not remove the pre-installed drain port hose barb fitting from the SoftPro control valve.
This houses a required flow restrictor and must be used.
Refer to the appropriate drain type.
This guide is intended for as a general reference. Your specific installation may vary from this guide.
Proper draining function may require an adequate air gap to prevent the possibility of wastewater being back-siphoned
into the treatment system.
Common drains include pre-installed softener loops drains, floor drains, laundry tub/sinks, washing machine drains and
sanitary sewer lines.
A) REPLACING AN EXISTING WATER SOFTENER:
Reuse the existing drain line.
NOTE:
The end connection to the softener’s control valve drain port hose barb fitting requires a ½ inch I.D.
vinyl tubing. Use a hose clamp to secure the tubing to the drain port.
B) PRE-INSTALLED SOFTENER LOOP DRAINS:
Typically, a pre-installed softener loop will have two pipes connected out from the wall with a third pipe for
the softener drainpipe (This drainpipe maybe capped separately or directly connected to the softener loop.)
