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 backwash cycle, your TITAN-Ox™ will send captured 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 1 1/2"
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. For backwash flow rates of 7 GPM or less, the
DLFC will be a black plastic elbow housing with 3/4 inch male NPT threads. This housing
contains a flow control washer that limits the backwash flow rate. For backwash flow rates
exceeding 7 GPM, the DLFC will be a black plastic straight housing with 1 inch male NPT
threads.
You will need to purchase suitable pipe or tubing for the drain line, either in 3/4 or 1 inch
diameter, to match the connection points on the drain line flow control assembly (DLFC). To
determine your MINIMUM drain line diameter, look up your model and incoming water
temperature using the chart below.
If in doubt, match the size of your drain line to the
thread size of the DLFC on your control valve.
