Place the bypass in the “bypass” position as pictured above.
Step 6. – Drain Line Installation
NOTE: NEVER CONNECT THE DRAIN LINE DIRECTLY INTO A DRAIN. ALLOW AN AIR-GAP
OF A MINIMUM OF 1 INCH (CHECK LOCAL CODES) BETWEEN THE DRAIN LINE AND
WASTE LINE TO PREVENT THE POSSIBILITY OF BACK-SIPHONING. ALWAYS FOLLOW
LOCAL CODES. THE DRAIN LINE SHOULD NOT BE EXPOSED TO FREEZING
TEMPERATURES.
During the regeneration cycle, your SoftPlus™ system will send water and contaminants out
the drain port. This port needs to be connected to a suitable household drain, ideally within
20 feet of your media tank. A nearby floor drain, sump pump, or a standpipe for a washing
machine is an excellent option. We recommend that the drain line be connected to a
minimum 1½" drain standpipe or floor drain located ideally below the top of the head of your
water filter.
Locate the drain port on the back of your control valve. The drain line flow control assembly
(DLFC) is pre-attached to the control valve - it has black plastic housing with 3/4 inch female
NPT threads.
You will need to purchase suitable pipe or tubing for the drain line. The minimum drain line
diameter is 1/2 inch although 3/4” is preferred. Polyethylene tubing, PEX, PVC, CPVC, and
copper pipe are all acceptable material choices for the drain line. If you are using flexible
tubing, be sure that there are no “kinks” or “crimps” in the tubing after installation that may
cause a flow restriction. If used, overhead drain lines are not to exceed a height of 5 feet
above the control valve and should be not more than 50 feet in length. Should an overhead
drain line be utilized, it is recommended that the drain line diameter be not less than 3/4”,
and that it not be fastened flush to the bottom of a floor joist to minimize noise transfer to the
upstairs of the building during regeneration.
Using an appropriate fitting, connect the drain line flow control to your drain line
tubing/pipe. The DLFC can be removed from the control valve to facilitate easier
plumbing if desired. To remove the drain line flow control, pull on the retaining clip to
remove it and then grasp the drain line flow control and pull upward. You may wish to dry-fit
