Polyethylene tubing, PEX, PVC, CPVC, or 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 be increased in size (diameter), 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 outward. You may wish to dry-fit the fitting first to make sure
you line up the drain line properly with the drain port on the control valve if you are using
rigid pipe.
Re-insert the DLFC into the control valve and securely lock into place with the retaining clip
when done.
Ensure that the drain line is thoroughly secured along its route to the drain. The drain line
will be under pressure when the backwash cycle is working. If not adequately secured, the
drain line could vibrate during backwash causing excessive noise. If this is experienced, use
additional fixtures to better secure the drain line.
Step 7 – Control Valve Set-up
During cold weather, the installer should warm the control valve to room temperature before
operating. Note: All electrical connections must be done according to local codes.
Plug the control valve into a standard, grounded 120 volt (60 Hz) electrical outlet. Be certain
that the outlet is uninterrupted and not controlled by a switch. An extension cord may be
used to reach a suitable electrical outlet. Ensure that the extension cord is UL/CSA certified
